The Best Testosterone Booster in 2026

Testosterone deficiency is a serious condition. It can cause weight gain, depression, loss of bone density, and reduced libido, among other worrying symptoms. But even if testosterone levels are within a normal range, men still lose about 1% of this vital hormone every year once they hit 40.1 That may not qualify as a clinical deficiency, but it can nonetheless present itself in symptoms.

Testosterone boosters seek to remedy the situation by supplying your body with nutrients that can cause you to produce more testosterone. The only downside is that dozens of companies are peddling "miracle" supplements, and they can drown out the safer, more effective options on the market. Our team has researched the top supplements in the field to determine which testosterone booster is likely the best for you.

If you're in a hurry, here's a breakdown of our top recommendations, and you can read on to learn much more about why we make these recommendations:

To break down an extremely packed and complicated landscape, we elected to assign the top several dozen testosterone boosters on the market to specific tiers:

• Recommended products: formulas and prices set to deliver top efficacy, safety, and value
• Top-tier products: options that would probably have been recommended if slightly better options didn’t exist
• Mid-tier products: products that may be too ineffective or too expensive to justify
• Bottom-tier products: those that are likely too expensive, too ineffective, or potentially dangerous; best avoided

Here’s a closer look at where each product we cover in this guide fell in our tiered ranking:

As you can see, the majority of products live in the bottom tier. That’s a sad reality of the testosterone booster market, but there are still nine products to consider between our recommended options and those in the top tier just below them. In the sections that follow, we’ll go into much more detail about how each product earned its place.

At Innerbody Research, we extensively research each health service we review, testing products and services ourselves to the greatest extent that we can. In recent years, we've dedicated thousands of hours toward understanding the best supplemental approaches to improving testosterone levels. All told, our team has read more than 185 research papers covering testosterone and the symptoms and treatment of testosterone deficiency. We also scrutinized research on the most common ingredients found in nutritional supplements aimed at raising testosterone. And we've become customers of all the top testosterone boosters on the market today, comparing their products and services.

Our testing, research, and discussions with experts led us to an undeniable conclusion: Though there were testosterone boosters worthy of recommendation, they all left something to be desired. Some excluded particularly useful ingredients. Others contained ingredients with too little scientific evidence indicating effectiveness. Some had wisely selected ingredients but included them in doses that were too low to be effective, according to scientific research.

We found ourselves wishing for a testosterone booster that we could recommend more full-throatedly — an affordable supplement that contains clinically relevant doses of ingredients that all carry scientific backing for testosterone enhancement. Rather than waiting around for some other company to produce it, we decided to create it ourselves. So, starting in 2024, our top-rated supplement has come from our own company. It’s formulated to be the best testosterone booster for the widest audience.

Despite entering this market, we’ve taken pains to remain objective. Throughout this guide, you'll find that we're quick to point out when a different option would be a better choice than our supplement. We spoke with a certified strength and conditioning specialist and a registered dietician to verify our findings and generate deeper insights into the field. We even had our managing editor (who happens to be writing this guide) try our product for himself for 12 weeks, and we’ll share his incredibly positive results below.

And like all health-related content on this website, this guide was thoroughly vetted by one or more members of our Medical Review Board for accuracy. Over the past two decades, Innerbody Research has helped tens of millions of readers make more informed decisions to live healthier lifestyles.

While they may not work for everyone, testosterone-boosting supplements can potentially improve total or free testosterone levels in men with clinically low testosterone levels or specific nutritional deficiencies. That, in turn, could result in increased energy levels and enhanced libido.

Of course, hormonal imbalances can wreak havoc on the body. Supplemental testosterone boosters like the ones in this guide aren’t likely to raise your levels to dangerous heights, but if you already have elevated testosterone, there could be a risk of increased aggression, acne, and even mania, according to one study.36

The trick is to get the right testosterone booster for your needs. If a vitamin D deficiency is suppressing your testosterone, a supplement with 100 ingredients but no vitamin D would likely prove ineffective (not to mention costly). That’s why, as we consider safety and effectiveness to be such critical factors, we heavily scrutinize ingredients and doses.

Next, we turn to more company-specific considerations, namely cost and customer service. Our cost estimation takes a few factors into account beyond mere price, and for our assessments of customer service, we’ve familiarized ourselves with the support infrastructures and shipping logistics of our top recommended brands by ordering directly from their websites and engaging with representatives as necessary.

Let's take a closer look at each category below to better understand the playing field.

Efficacy

Winner: Testosterone Support by Innerbody Labs

A lot of testosterone boosters on the market share common ingredients, but the quantities and combinations of the ingredients vary from product to product. When we evaluate a given testosterone booster, we look for a few specific markers that can support claims of efficacy:

We also put our product to the test, having our managing editor take it for 12 straight weeks along with baseline and follow-up testosterone measurements. At the end of 12 weeks, he’d more than doubled his free and total testosterone, moving from a near clinical deficiency to the high range of normal.

We’re confident that Innerbody Labs' approach offers you the best path to see a noticeable uptick in your testosterone levels and an improvement in symptoms associated with low T, but a few other testosterone boosters are worth your consideration, as well.

Roman's Testosterone Support supplement does an excellent job of balancing safety and efficacy in a very affordable product. It delivers meaningful doses of ashwagandha, zinc, and maca, but a lack of fenugreek and longjack (tongkat ali) means it may not pack quite the same punch as its competitors. Mars Men provides more ingredients at higher doses than Roman, but it lacks ashwagandha. For some men, especially those who may need to avoid ashwagandha for its potential to influence thyroid hormones, this sacrifice is less detrimental to their journey.16 But others will miss out on one of the most thoroughly researched botanicals for testosterone support on the market.

Here’s a quick look at how ingredient bills compare among the top testosterone boosters on the market. To make the chart a little easier to navigate, we excluded ingredients in some products that lack sufficient clinical support for testosterone improvements and men’s sexual health.

These products each take slightly different approaches to managing low testosterone. Companies like Mars Men prefer to load up on large but clinically untested doses of well-researched ingredients. Others, like Nugenix, include a few of those ingredients at proper doses but alongside others with much less scientific support. Ultimately, Innerbody Labs strikes the best balance, excluding unnecessary and poorly researched ingredients and keeping close to doses used in the most successful human studies to date.

Safety

Winner: Testosterone Support by Innerbody Labs

Some testosterone boosters combine a handful of well-researched ingredients with lesser-known botanicals that have plenty of anecdotal history but little scientific rigor to back them up. But if safety is your primary concern, you may want a testosterone booster that only includes well-researched ingredients, like Testosterone Support by Innerbody Labs. All of its doses are clinically relevant, but none of them are the potentially unsafe megadoses you’ll sometimes see other companies provide.

There’s also an opportunity in testosterone-boosting supplements to add ingredients that can account for the potential adverse effects of others. For example, Roman and Innerbody Labs are the only two to offer T boosters that include copper as an offset to zinc, which has been shown to deplete copper levels.2

The top supplements in this guide may have certain ingredients that pose some risks, such as ashwagandha’s potential influence over thyroid hormone levels,16 but those risks are either extrapolated from related data or currently only exist as case studies. If anything significant were to come out regarding the safety of this or any other ingredient in our top recommendations, we would let you know in this guide and seek a safer and better formula.

Cost

Winner: Roman

When we evaluate the cost of a testosterone booster, we consider its price and any potential avenues for savings, including bulk and subscription discounts. We also look at money-back guarantees and return policies that can affect your investment.

The winning position for this category goes to Roman because it provides you with its testosterone booster on a subscription basis for $35/month billed monthly or $29/month billed quarterly. This price has stayed the same even as Roman recently improved upon a formula we already appreciated.

For the record, a similar subscription model for Innerbody Labs' Testosterone Support can bring your cost per bottle down to $47 if you subscribe to twice-yearly deliveries. We believe this presents the best value on the market, but it’s not the least expensive option.

Customer service

Winner: Roman

Roman is more than just a testosterone-oriented company. It has grown into a telehealth juggernaut over the years whose range of offerings includes hair loss treatments, erectile dysfunction (ED) treatments, and weight loss services. Its expansion coincided with growth and refinement in customer service, with a sleek, intuitive website.

Roman sometimes offers testosterone testing as part of its available services, making it a one-stop shop for men who want to get a diagnosis and treatment for their low testosterone. However, the company periodically suspends this offering as its related clomiphene citrate prescription has faced some availability issues. We wish it would keep the testosterone test on its site regardless of availability.

There are no fees associated with pausing or canceling your subscription, and Roman’s shipping is extraordinarily fast. When we ordered the company’s Testosterone Support, it was on our doorstep in less than 48 hours.

Close to 95% of testosterone is produced by the testicles. "The other 5% is produced by our adrenal glands," explains Dr. Isabel Urdaneta, a urologist and member of our Medical Review Board. But men produce less testosterone as they age, and men over 40 lose testosterone at a greater rate than men under 40 — a phenomenon sometimes called male menopause.3 Men can experience symptoms of reduced testosterone as early as 30 (it's mostly those over 40 who will notice the changes), but lower-than-normal testosterone levels can occur no matter your age. Clinically low testosterone is also known as male hypogonadism, and it causes numerous symptoms.

"In the patient with hypogonadism, changes in mood, personality, [and] thriving are evident," says Dr. Urdaneta.

We also spoke to Reda Elmardi, a registered dietitian and certified strength and conditioning specialist, who told us low sex drive is at the top of the list of symptoms. "Low sex drive can be caused by many things, but the most common cause is low testosterone levels," Elmardi said. "If your body has low testosterone levels, then you may not feel like having sex at all. This could lead to erectile dysfunction."

Here is a fuller list of common warning signs to look for:

• Low libido (sex drive)
• ED
• Depression
• Brain fog and memory issues
• Fatigue
• Moodiness
• Irritability
• Weakness
• Hair loss
• Increased body fat

If you notice any of these symptoms, it doesn't necessarily mean you should jump right into a testosterone booster regimen. Most of the symptoms are quite common across various conditions, such as lupus and iron deficiency.

Dr. Urdaneta also adds, "It is very important to make a differential diagnosis with depression; they have extremely similar symptoms. Many patients who go to urology thinking that they have low testosterone generally have some degree of depression, so it is indicated to consult psychiatry."

You should always talk to your physician before beginning any supplement and, in this case, see if they can order testing for your testosterone levels. At-home testing is a viable option, too, if you don’t have a primary care provider.

At-home testosterone tests

If you know for a fact that you have low T, you can confidently seek out a supplement or replacement therapy to remedy the situation. But for those who aren’t sure whether their testosterone is low, at-home tests make it tremendously easy to measure their levels. You can see our favorite at-home testosterone tests in our comprehensive guide, many of which you can get with a discount as an Innerbody reader.

Some at-home tests check for multiple markers that can give you a clear picture of your hormonal health. Our current top pick comes from Maximus Tribe, which uses a painless blood collection method and offers data on testosterone, as well as other biomarkers critical to monitoring safety and efficacy during testosterone replacement therapy.

In our opinion, the best testosterone booster currently on the market is Testosterone Support by Innerbody Labs. It offers some of the best-researched ingredients for addressing low testosterone levels, and it provides those ingredients in quantities that studies have shown to be effective and safe.

Take a look at the chart below to see how top testosterone boosters compare. “Best price” reflects the lowest amount you’ll pay with a company’s largest bulk order or subscription platform.

Testosterone boosters work on different parts of your endocrine system, depending on their ingredients. In most cases, they’ll stimulate the production of either testosterone directly or something like luteinizing hormone (LH) from the pituitary gland, which will signal the testes to make testosterone.35

There are also testosterone-boosting ingredients that don't increase the amount of testosterone in the body but decrease the volume of sex hormone-binding globulin (SHBG), which binds to testosterone, reducing the amount of free testosterone that your muscles and other critical systems can use. By suppressing SHBG, you can effectively increase your free testosterone from your regular testosterone supply.

Understanding how a given product can help raise your testosterone levels starts with understanding its ingredients. In addition to the components included in our chart above, there are others that are likely helpful. Many have a fair amount of credible research behind them and could combine to make a robust product. But credible research isn't necessarily statistically or clinically significant, and too many studies rely on participant sets that are too small to correlate with the general population.

Here's a breakdown of our top ingredients to look for in a testosterone booster:

Free testosterone vs. total testosterone

One confusing topic in the testosterone sphere is the difference between free and total testosterone. Some research will point toward an ingredient’s ability to boost total testosterone, but this doesn’t necessarily mean it will yield any of the benefits you’d want from a testosterone booster.

The essential difference between free and total testosterone is that total testosterone measures both free testosterone and testosterone that’s bound to proteins like SHBG. Your body can’t use the testosterone in that second camp to help improve exercise performance or burn fat. Only free testosterone truly matters for most low T concerns, and it typically makes up just 2-5% of your total testosterone. A measure of total testosterone includes free testosterone, so a study showing that an ingredient boosts total testosterone without explicitly showing an increase in free testosterone doesn’t necessarily undercut the ingredient’s potential, but it does demand further research.

Ingredients like fenugreek, zinc, and boron have been shown to increase free testosterone.11 8 9

Most testosterone boosters should be completely safe for the majority of users. However, because some ingredients can affect blood flow and influence the activity of the testes and other parts of the endocrine system, we highly recommend speaking to your doctor before starting any new regimen to increase testosterone.

As a registered dietitian, Elmardi doesn't seem too worried.

"The safety of testosterone boosters has been questioned due to the fact that some of them have been linked to side effects like liver damage and heart problems.15 However, these risks are rare and typically only occur if you take too much of the supplement. If you use a safe dosage, you should not experience any negative side effects."

That said, some testosterone-boosting ingredients have been associated with specific adverse effects. For example, studies suggest that ashwagandha can help treat hypothyroidism (low levels of certain thyroid hormones).16 That has led some researchers to fear that it may be dangerous for anyone on thyroid medications or those with even mild hyperthyroidism.

Also, one study looking at the chronic, high-dose treatment with D-aspartic acid in frogs suggests a danger to certain organs (namely the kidneys, heart, brain, liver, and testes) in the form of oxidative stress.17 However, the concentrations used in the study were far higher than those shown to be most effective in elevating testosterone levels, lending credence to Elmardi’s opinion.

You’ll want to watch for some additional side effects, if only to give yourself peace of mind; should you experience one of them, you'll know where the problem originated. Side effects of the most commonly used ingredients in testosterone boosters include:

• Headache
• Irritability
• Stomach discomfort
• Nausea
• Vomiting
• Diarrhea

Such side effects typically resolve on their own as your body acclimates to new supplement ingredients, while others can be ameliorated by taking the supplement with a meal. If any of them linger past a week or two, you should stop taking the product and talk to your doctor.

By comparison, testosterone-replacement therapies (TRTs) introduce significantly more risk than supplements. Injectable testosterone can cause mood problems and other effects from dramatic swings in testosterone concentrations.36 And gels and creams can leave a residue and transfer to women and children. There are reported instances of early-onset puberty and unexpected hair growth in children unknowingly exposed to testosterone-boosting gels.58 But if you exercise caution and use thorough cleansing practices, you and your loved ones should be safe.

Best overall

After spending the better part of a decade researching low testosterone and the different ingredients various companies use to address it, we’ve learned which ones should work and which ones probably won’t. But when we looked across the field of options, we saw deficiencies in every brand — even the products we considered easiest to recommend.

So we decided to create a testosterone support supplement that could fill the gaps and offer more men the highest likelihood of success. We’ve employed only the ingredients that have the most consistent research to support their ability to increase testosterone. In some cases, we also included ingredients designed to maximize the potential of our testosterone-boosting ingredients (like black pepper extract, which doesn’t boost testosterone but does improve the absorption of other ingredients).40

We’re aware that it’s hard to come off as objective when you have a product in the mix, but we’ve placed the ingredients, doses, and prices of our top competitors side-by-side, and we’re confident that our product is the likeliest to help the most men. We’re also sober about the reasons you might choose another company — and there are other very worthy options. For example, ours is not the least expensive among your good options (that would be Roman), and some of our most important ingredients can be found in Roman and Genius Test, both of which cost less.

But Innerbody Labs includes useful ingredients you can’t find in those testosterone boosters; for instance, Roman lacks fenugreek and tongkat ali (longjack), while Genius Test doesn’t contain any zinc or vitamin D.

Additionally, competitors' doses don't always meet the level that scientific research would suggest they should. Case in point, although Genius Test uses a branded form of longjack root extract, the quantity is subpar. Our supplement provides relevant doses of every key ingredient.

There are also some testosterone-boosting ingredients with a bit of research support that we considered adding but ultimately did not — like D-aspartic acid and boron. We chose to exclude those because we’ve seen enough conflicting evidence around the former and too sparse a collection of evidence around the latter that it seemed wiser at this time, for both safety and efficacy reasons, to leave them out. In doing so, we’re able to deliver what we feel to be more effective doses of the more promising ingredients while keeping the final cost lower for you. (For instance, Nugenix’s Total-T Maxx includes more of these debatable ingredients but costs nearly $100 more than our product.)

Here’s a quick look at the ingredients in Innerbody Labs Testosterone Support, along with relevant links to just some of the studies showing why we chose them at their specific doses:

• Ashwagandha: 600mg KSM-6641
• Fenugreek: 600mg11
• Maca: 3,000mg42
• Longjack: 400mg43
• Vitamin A: 750mcg44
• Vitamin D: 1000 IU45
• Vitamin K2: 75mcg46
• Zinc: 25mg citrate2
• Copper: 300mcg47
• Selenium: 20mcg48
• Black pepper extract: 5mg40

Our botanical testosterone-boosting ingredients are dosed as high as — or higher than — nearly any of our competitors, and no other product has doses this high of ashwagandha, fenugreek, maca, and longjack combined. What we offer, we believe, is the best value on the market.

Our editor’s experience using Testosterone Support

Coming out of a particularly stressful time in his life, our managing editor, whose tests had revealed near-clinical testosterone deficiency for years, decided to take our supplement regularly for 12 weeks to see what would happen. The results were impressive, with a 2.53x increase in free testosterone and a 2.15x increase in total testosterone, and other biomarkers maintaining evidence of good health.

We used Maximus Tribe (described below as our top source for online TRT) for testing. Here’s a look at the results:

Granted, these are purely anecdotal results, but they still help illustrate the potential this supplement offers to regular men who aren’t bodybuilders or even very serious athletes.

Pricing and shipping

Innerbody Labs adopts a pricing structure that provides simplicity and transparency. You can make one-time purchases or subscribe, with subscription tiers offering more and more savings as they get larger.

Here’s how it breaks down:

Shipping is fast and free on all orders, although orders outside the U.S. may incur duties, taxes, and fees according to the policies of the destination country. A 30-day money-back guarantee is also in place to protect your purchase. Note that customers in Canada and Australia can’t order more than a 90-day supply due to personal exemption limits for supplement imports.

Best budget pick

Roman has grown into one of the most comprehensive men's health providers online. Its range of high-quality products and services is right up there with competitors like Hims. It has additional products for hair loss, sexual health, weight loss, and more. But unlike some of its competitors, Roman has developed a testosterone program that includes:

• A testosterone booster supplement with well-selected ingredients
• At-home testosterone testing
• Prescription clomiphene

Initially, Roman only offered its nutritional supplement as a means to treat low testosterone. It then added an at-home testosterone test and prescription therapy. (We also have a comprehensive review of the best at-home testosterone tests.)

NOTE: In 2024, Roman temporarily suspended its testing and prescription services for testosterone. They have yet to return, and the company’s support team remains vague about when — or if — they will. We'll continue to monitor the situation and update this page should Roman bring its testing and prescription support back online.

When it comes to prescription clomiphene, you should know that it isn't a TRT. A proper TRT contains the hormone itself, which you get into your body with topical creams or injections. Clomiphene doesn't contain any hormones, but it signals to your brain that there isn't enough testosterone in your system, leading to an increase in production. The results of clomiphene trials in men are impressive, and the side effect risk is low.49 This is in stark contrast with testosterone replacement, which is associated with a litany of side effects, including fertility issues.

There are some causes and cases of low testosterone that are too severe for clomiphene to be effective, but it's a very promising testosterone booster for men who don't find success with nutritional supplements or those who want to skip ahead to stronger, more clinically supported treatments without reaching for testosterone replacement.

Testosterone testing

Roman offers an at-home testosterone test you can use to determine whether your T levels are low enough to warrant treatment. The test includes a free consultation with a provider after you receive your results to help you determine next steps. (Again, note that Roman temporarily paused this testing service in 2024. It has yet to resume.)

At-home testosterone testing requires you to draw two finger-prick blood samples soon after waking on successive days and after a fast of at least eight hours. Time-of-day requirements vary based on your age, however. Dr. Urdaneta tells us: "After 50 years, there is no variability with testosterone secretion, so there is no need to wait for morning measurements."

You'll mail the samples off to a Roman-affiliated lab and see the results within a few days.

Testing from Roman costs $69, which is low when compared to other providers, like LetsGetChecked or Everlywell. However, the American Urological Association recommends at least two testosterone tests to determine if an individual has low testosterone;18 various factors — including recent exercise activity and diet — can impact testosterone measurements. Roman's competitors all provide just one sample collection per kit, meaning you'll have to spend twice as much money to get a reliable diagnosis.

If your test reveals low testosterone levels, you can talk to a Roman-affiliated provider to determine whether you want to take the nutritional supplements or seek a prescription remedy. If you choose prescription clomiphene, there's an ongoing program you can be part of, which we get into below.

Testosterone Support nutritional supplement

Roman's Testosterone Support nutritional supplement has long been one of the simpler options on the market. Instead of throwing over a dozen ingredients at the trouble and hoping one or two get the job done, Roman confines its formula to ingredients with a fair amount of scientific research behind them:

• Ashwagandha: 600mg
• Zinc: 30mg
• Magnesium: 350mg
• Vitamin D3: 20mcg
• Maca: 3,000mg
• Copper: 2mg
• Calcium: 70mg
• Sodium: 10mg

Roman updated the ingredient bill back in 2024 to include small amounts of calcium and sodium. It also increased its maca dose from 2,000mg to 3,000mg and decreased its D3 dose from 50mcg to 20mcg. The maca increase brought it more in line with research into positive erectile performance studies, while the decrease in D3, though significant, still offers enough to help men who aren’t quite clinically deficient to stay up on their D levels.

The copper in Roman Testosterone Support is critical. Very few testosterone boosters or male enhancement pills that contain zinc also contain copper, yet studies consistently show that increased zinc supplementation can contribute to copper deficiency.47 So including copper here ensures that your mineral balance remains constant throughout treatment. Innerbody Labs Testosterone Support is the only other T booster in its class providing copper alongside zinc.

Roman Testosterone Support pricing

Your first order from Roman used to come with a jar capable of holding a month's worth of testosterone support. Subsequent shipments arrived in pouches that you would tear open and use as refills for your jar. This was an aesthetically pleasing, potentially environmentally friendly approach, but the company recently abandoned it for unclear reasons. Now, like most other supplements, it comes in a simple, disposable bottle.

There are two available billing cycles for Roman Testosterone Support:

• Monthly plan: $35/month
• Quarterly plan: $29/month (billed quarterly at $87.30)

This makes Roman the least expensive option among our top picks, and we've consistently experienced extraordinarily fast shipping from its distribution centers. (Plus, that shipping is free with a subscription.)

Prescription clomiphene

Men who are diagnosed as having low testosterone will have the option to seek prescription assistance through Roman in the form of clomiphene. Clomiphene, a selective estrogen receptor modulator, is currently FDA-approved for treating infertility in women whose ovaries fail to produce adequate numbers of eggs.19 But doctors have begun prescribing it off-label for use in men with low testosterone after a series of clinical studies showed it to be both safe and effective as a testosterone booster.

Clomiphene effectively normalizes testosterone levels in about 80% of users, based on a few clinical studies that relied on self-reported increases in libido and energy or decreases in body fat or mood disorders.20 TRT seems to be somewhat superior in terms of results, but it's also associated with a higher incidence of adverse effects.

If Roman restarts this program at its previous rate, and your testosterone tests reveal low testosterone levels, you can get continued testosterone monitoring and prescription delivery at the cost of $165/month. That said, we have no hard data on when this program will restart, if ever, or whether pricing will change. As a point of comparison, you could go through Maximus Tribe for a similar treatment experience and pay just $99/month plus the cost of testing.

For men without insurance, these are good deals. But we cross-referenced the formularies for several major insurers, and if you have insurance, you can likely get coverage for clomiphene. With insurance coverage, you'll likely pay substantially less per month than $165, and you can retest using a Roman kit after a few months of treatment have elapsed.

Roman return policy

Roman's return policy is a bit unclear. It states that it cannot provide refunds for any prescription products, but its testosterone booster — and many other products on offer — do not require a prescription. Still, when pressed on the issue, Roman stated that it doesn’t accept returns on Testosterone Support. This is frustrating and disappointing when you consider that other companies offer money-back guarantees, allowing you to try their products with some risk reduction.

Best for men outside the U.S., U.K., Canada, and Australia

The Genius brand focuses more on cognition and sports performance than sexual health, with numerous nootropics and workout supplements in its lineup. Many of these are very well-formulated, and its testosterone booster is up there among its best products.

Here’s a quick look at the ingredients:

• Ashwagandha: 1,000mg KSM-66
• Shilajit: 500mg PrimaVie
• Fenugreek extract: 500mg
• Quercetin: 250mg
• DIM: 250mg
• Longjack: 100mg LJ100
• Boron: 10mg

Two things stand out about this formula. First, it’s a high dose of ashwagandha, offering 1,000mg where most others stick to around 600mg. With so much research relying on that 600mg dose, it’s hard to know why a company would offer more, other than to look stronger without much scientific merit to the increase.

The other thing that sticks out is that boron is the only thing making up the product’s vitamin and mineral content. It’s common to see things like vitamins D3 and K2 alongside zinc and copper in a high-quality testosterone booster. But those are noticeably absent here.

Still, for shoppers outside the U.S., U.K., Canada, and Australia, Genius is probably the next best thing to Innerbody Labs Testosterone Support, which is limited in shipping scale to those three regions.

Genius Test pricing and returns

On the Genius website, a single bottle costs $58 for a one-time purchase or $46.39 for a subscription. But if you’re going through iHerb to ship internationally, your prices will be a bit different. You can still get a one-time purchase through iHerb for $58, but the subscription discount is less, dropping the price to just $52.19.

The good news is that iHerb has a pretty solid 30-day return policy. But it’s worth noting that only domestic U.S. shoppers get prepaid return shipping labels. International customers are responsible for their own shipping.

Best if you can’t tolerate ashwagandha

Ashwagandha isn’t an especially divisive ingredient. It has a pretty low risk of side effects, and it’s not commonly contraindicated.7 Still, for men who want to avoid it for whatever reason — medical advice, a negative GI response, or just a lack of success trying ashwagandha in isolation in the past — there aren’t a lot of high-quality options in the testosterone-boosting space.

That scarcity is largely due to how successful ashwagandha has been in testosterone research, but there’s still hope in the form of a few ashwagandha-free products, including Mars Men. Of the few testosterone supplements we scrutinized that didn’t have any ashwagandha in them, Mars Men was easily the best.

Here’s a look at the Mars Men ingredient bill:

• Tongkat ali: 1,000mg
• Fenugreek: 1,000mg
• L-Taurine: 675mg
• Shilajit: 400mg
• Boron: 4mg
• Vitamin D: 100mcg
• Zinc: 30mg
• Vitamin K1: 100mg
• Vitamin K2: 100mg

As you can see, Mars Men tried to make up for the missing ashwagandha by increasing doses of fenugreek and tongkat ali. It’s a compelling strategy, but most of the evidence supporting either ingredient uses lower doses, so there’s no guarantee that increasing to 1,000mg each would make a significant positive difference.

There’s also an issue with the shilajit selection here. The best research connecting shilajit with testosterone improvements uses 500mg of PrimaVie-branded shilajit, a purified form that reduces the risk of heavy metal contamination associated with this particular ingredient. Mars Men uses just 400mg of an unbranded shilajit, so the dose is a little low. But at least the company submits its product to third-party testing for an added degree of safety.

Mars Men pricing and returns

Mars Men uses a subscription-only model, so there are no one-time purchases. Of course, canceling is penalty-free, so you could buy one bottle, then cancel, effectively creating a one-time purchase. But that’s true of any subscription system in our guide. Either way, that would cost you $59/month — a pretty reasonable price for the ingredient bill but still more expensive than two of the four subscription tiers with Innerbody Labs.

Mars Men has a better return policy than most, however, offering 90 days for you to try its supplement. That should be enough time to start noticing changes in the most common symptoms of low testosterone.

If using a testosterone booster doesn't solve your problems or you've received a clinical hypogonadism diagnosis, you may require more than dietary support. That's where TRTs come in. The purpose of these therapies is to add testosterone directly to the body, often with targeted supplementation or medication. They’re often a last resort for men who’ve been unsuccessful with other treatments or those whose T levels are low enough to warrant specialized treatment. However, they can be much more dangerous than other methods, with side effects that include hormonal imbalances resulting in aggression, acne, mania, and infertility.25

TRT typically involves delivering exogenous testosterone to your system, either through injection or transdermal means like a patch or topical cream. These modalities each have their good and bad points. Here’s how they compare:

You can also take certain prescription medications designed to increase your testosterone levels through various mechanisms of action. They’re generally a little less effective than traditional TRT but still more effective than a testosterone-boosting supplement, and they’re often more than enough to take care of clinical hypogonadism in most men.

A doctor may prescribe these alone or in combination according to the symptoms you present, the results of any tests you take, and your goals for therapy.

Several telehealth companies offer access to prescription testosterone interventions, with consulting physicians on staff and available testosterone testing. The one we've identified as having the best prices and the widest array of treatments is Maximus Tribe.

Best prescription treatment provider

Maximus Tribe is a fully online medical clinic specializing in testosterone treatments, but with other products for anyone, including weight loss and blood flow products. There are plenty of similar companies out there with good catalogs, but certain stark differences make Maximus a better choice for most men seeking online TRT.

For example, competitor Hone Health operates on a membership model, with Basic and Premium levels available at two very different prices. Basic costs $25/month, whereas Premium costs $160/month. You need the latter to get the full suite of biomarker testing available. With Maximus, there are no membership fees. The medication costs a bit more, but your overall expense is less.

On the testing side, a Maximus testosterone test looks at the following biomarkers:

• Total testosterone
• Free testosterone
• Vitamin D
• LH
• FSH
• Estradiol
• SHBG
• Alanine aminotransferase
• Total prostate-specific antigen (PSA)

It’s critical that these other biomarkers are part of any TRT regimen, as things like total PSA and estradiol can imply certain reactions to medication that could cause you to switch to something else for safety reasons.

Maximus offers a good range of TRT treatments, the best of which for most men is likely to be enclomiphene citrate. This medication isn’t like a traditional TRT treatment that introduces outside testosterone into your body. Instead, it causes a response from estrogen receptors that tricks your body into producing more of its own testosterone.60 The result is a more gradual testosterone increase than what you get from injections and creams, reducing things like mood swings and ensuring a higher degree of safety overall, including a preservation of fertility, which traditional TRT often blunts.52 61

Maximus testosterone pricing

Here’s a quick look at the pricing you can expect with Maximus Tribe for its testosterone treatments and testing:

• Testosterone testing: $99.99
• Testosterone injections: $99.99
• Oral testosterone: $149.99
• Testosterone cream: $109.99
• Enclomiphene citrate: $99.99
• Oral T and enclomiphene bundle: $199.99
• Testosterone cream and enclomiphene bundle: $189.99

Unlike nutritional supplements, most Maximus products are prescription-only and created in compounding pharmacies specific to your order. All of the company’s products ship for free, but there really isn’t any money-back guarantee or return policy to speak of. That said, our customer service experiences with Maximus have always been solid, with quick answers to even more complex questions about products and testing.

In selecting the handful of testosterone boosters that made it into our summary of recommendations, we considered dozens of others. Some of these were very good products that just barely fell short of earning our recommendation; others were poorly formulated, poorly priced, and potentially unsafe. Still others were simply mediocre, drowned out by a small chorus of superior options despite having some potential to work in isolation.

You may have seen some of these brands infiltrating your algorithm and peppering your social media feeds with ads and offers, but that doesn’t necessarily mean they’re good products. Below, we take a look at products in the three quality tiers described earlier to let you know why they didn’t make the cut and why you should look elsewhere.

Products in this tier are generally well worth your money. They have pretty good ingredient bills containing well-researched ingredients at clinically relevant doses. But in every case, something about them was inferior enough to one of our top recommendations that there was no room for them in the main lineup.

You could go so far as to consider these honorable mentions, but unless you want to spend more to get less, you’re better off keeping with a recommended product from further up the page.

Let’s break this tier down to discover where these products fell short.

Nugenix Total-T Maxx

Nugenix offers several testosterone boosters, and Total-T Maxx is its most expensive at $169/month. It also offers the largest list of ingredients, many of which have good potential for treating low testosterone:

• Vitamin D: 20mcg
• Zinc: 15mg
• Fenugreek extract: 600mg
• Ashwagandha extract: 600mg
• Shilajit purified extract: 500mg
• Tesnor: 400mg
• Eurycoma longifolia extract: 150mg
• Rhodiola extract: 150mg
• Maca extract: 150mg
• Asian ginseng extract: 140mg
• Black ginger extract: 90mg
• White button mushroom extract: 10mg
• Black pepper extract: 5mg

The standouts here are ashwagandha, shilajit, Tesnor, zinc, and vitamin D. If Nugenix had left the list there and charged less, it might have met a better fate in this guide. But the price, along with questionable inclusions like white button mushroom and black ginger extracts, make it very hard to recommend.

Alpha Jym X

Our editors are fans of Jym in some cases; the company has consistently been included in our guide to the best muscle-building stacks. If it were to start having a third party test its supplements, it might see more of its products get recommended throughout our various fitness pages.

Its testosterone booster, Alpha Jym, actually comes in two varieties: Alpha Jym and Alpha Jym X. The non-X version isn’t even worth talking about, but the X version is much more compelling. It contains the same 600mg of KSM-66 ashwagandha and fenugreek extracts you’ll find in our top overall pick, as well as a safe and potentially effective 5mg of boron. It also contains somewhat underwhelming doses of shilajit and tongkat ali, at 250mg and 100mg, respectively.

But Alpha Jym X does something a bit odd. It offers you the option to double your dose, taking eight capsules daily instead of four. That brings those middling doses of shilajit and tongkat ali up to snuff, but it also forces you to take 1,200mg of both fenugreek and ashwagandha — doses that have no clinical support and could increase your side effect risk. What’s more, for ongoing users, it doubles the cost of the product.

So, without a clear lane to maximize efficacy, safety, or cost control, Alpha Jym X didn’t make the cut.

Innosups T-Drive Apex

Like Jym, Innosups offers multiple versions of its T-Drive supplement, with regular, Magnum, and Apex available. This time, however, the differences among them are frustratingly nuanced. All three are priced nearly identically, from $53 to $56 per month.

Regular T-Drive is a fine supplement, with good doses of ashwagandha, fenugreek, boron, D3, and zinc.

Magnum appears to place a greater emphasis on ingredients with more support for erectile health than testosterone production, removing the ashwagandha and replacing it with horny goat weed.50 There’s also slightly more zinc but less fenugreek.

Apex maintains the ashwagandha content and higher levels of zinc seen in the original formula, but it opts for a different brand of ashwagandha that has a little less research in the testosterone space than KSM-66 despite being more potent in head-to-head research.59 It’s a bit of a gamble considering the weight of testosterone-related evidence that supports KSM-66, but it could be right for some men.

Apex also loses some points for dropping the fenugreek dose as well, and for introducing some questionable ingredients with little or no human data supporting them, like curculigo root extract.

If Innosups could take the best parts of each of its three formulas and combine them into a better supplement, it might have a chance to crack our top recommendations.

VThrive Ultimate Man-T Advanced

VThrive is an in-house brand from The Vitamin Shoppe, and we were genuinely surprised at the quality of its testosterone booster, Ultimate Man-T Advanced. It boasts clinically relevant doses of KSM-66 ashwagandha, fenugreek, tongkat ali, and shilajit, as well as solid doses of D3 and zinc, with copper included to offset zinc’s potential copper depletion.2

However, in a head-to-head comparison with Innerbody Labs, it falls a bit short:

Yes, VThrive has shilajit, which Innerbody Labs does not. It also has a slightly higher dose of D3. But it has no K2 to help with that D3 metabolism. It also lacks maca and selenium, as well as black pepper to improve nutrient absorption. And its best monthly price is nearly $20 more than Innerbody’s.

If we gave out points for second best, VThrive would have been in contention for that silver medal. However, as it is, it got left behind.

Brickhouse Nutrition Force

Brickhouse Nutrition has a relatively small catalog, with just over 20 products at the time of this writing. Its lineup is mostly concerned with longevity and aesthetics, with greens powders, collagen, and weight loss supplements among its headliners.

Its testosterone booster could be considered something of an outlier, but it stands out among its competitors for its commitment to erectile performance. While most other testosterone boosters might include one or two ingredients aimed more squarely at erectile health than testosterone production, Force’s ingredient bill boasts at least six ingredients with more support for erectile performance than testosterone, including L-arginine, epimedium extract, and Tribulus terrestris.

However, some of its botanicals aren’t real contenders for either testosterone boosting or erectile performance, with things like cyanotis root, cnidium seed, and ajuga turkest leaf coming over from traditional medicinal practice without quite enough scientific support to convince us of their efficacy. That said, if your low testosterone manifests with ED as a symptom, and that ED is mild enough, this supplement could serve as an effective one-two punch.

The biggest issue with Force is its zinc content, which ultimately kept us from recommending it any higher than this tier. It delivers 50mg of elemental zinc per serving — 10mg above the tolerable daily upper limit set by the NIH.62 Routinely consuming that much elemental zinc could lead to GI symptoms, copper deficiency, and other health problems.

Pricing is also where things get tough for Brickhouse, as its system only offers subscriptions at a cost of $169.95/month. To put that in perspective, Force contains a total of 16 ingredients, only two of which have significant human research supporting their specific doses for testosterone improvements. By comparison, Innerbody Labs Testosterone Support contains 11 ingredients, all of which either have a direct correlation to testosterone improvements at their given doses or are there to play specific, scientifically supported roles in maximizing the safety and efficacy of the others. And for $170, you could get a three-month supply from Innerbody Labs and still have enough left over for a latte.

Products in our middle tier fall a bit shorter than those of the tier above. They typically have too many exclusions, too many unsupported ingredients, or price points that don’t justify the sacrifices in their formulas. However, few boast all three problems (we saved those for our bottom tier), so there are some instances where relative simplicity and reasonable pricing make for simply mediocre products that could have made the top tier if they’d cost less.

Let’s explore this tier further to see what shapes these products take.

Essential Elements T-Hero

Essential Elements does two things really well right out of the gate: it subjects its product to rigorous third-party testing, and it keeps the price of its base product, T-Hero, reasonably low. That’s important considering how short the ingredient list is. It contains just five ingredients, one of which lacks enough scientific support for us to believe it’ll make a major difference in testosterone levels.

The other four ingredients are well-dosed, but the ashwagandha extract doesn’t appear to be standardized in any way, so it’s hard to compare to superior ashwagandhas like KSM-66 and Shoden.

The company also makes T-Hero Platinum, for which you’d have to pay nearly twice as much to upgrade your ashwagandha to Shoden and add a proprietary blend of ingredients that’s too small for any one of them to be effective.

Swolverine ZMT

With ingredients like melatonin, GABA, valerian root, and L-theanine, ZMT is, first and foremost, a sleep aid. That said, it also contains enough ashwagandha and zinc to potentially boost testosterone. But those doses are a little off. There’s only 300mg of KSM-66 ashwagandha, when 600mg is more typically seen in the research.7 And there’s 50mg of zinc here, a full 10mg over the NIH’s tolerable upper limit. That means you could easily encounter side effects related to too much zinc consumption, especially if you already get enough of it in your diet or from other supplements.

What’s more, this is a supplement you’re meant to take daily, and daily consumption of melatonin isn’t something we’d recommend from a safety perspective.

Ultimately, ZMT is useful as an occasional sleep aid that has some good T-related ingredients in it. You could use it from time to time alongside a more streamlined T booster, like Roman T Support, but it’s not a solid choice as a T booster on its own.

Xendurance Test+

Xendurance starts out strong, with a 600mg dose of KSM-66 ashwagandha, 500mg of fenugreek, and 400mg of longjack. But doses after that start to falter, with just 200mg of Tesnor when 400mg is superior, and 100mg of shilajit when we usually see 500mg getting the job done.23 57 It’s probably as close as you can get to a top-tier product without quite cracking into that upper echelon, especially with a subscription price as low as $54, but there are simply better products out there for around the same amount of money.

That said, if you find that Xendurance has other products you’re interested in, it might benefit you to become a member with the company. It costs a one-time fee of $100, but it knocks an extra 15% off most products, bringing the cost of Test+ down to just $45/month.

1st Phorm Primal-T

Primal-T from 1st Phorm gets its ashwagandha and boron content right, but its other ingredients and doses raise questions.21 It splits its longjack root extract in half between a branded extract and an unbranded one, and it includes DIM, an ingredient with only animal studies supporting its relationship to testosterone. Its only mineral inclusion is calcium, which hasn’t been connected with testosterone in the literature.

Despite these shortcomings, 1st Phorm prices its supplement like a premium product, charging $62 for a one-time purchase and $60 for a subscription. Given that something like Innerbody Labs Testosterone Support boasts superior ingredient selection and doses for a similar cost — even less with its highest subscription tier — you can see why Primal-T fell to its current position.

Transparent Labs Vitality

Transparent Labs is known for its attention to detail and third-party testing, but some of the doses in its testosterone booster, Vitality, fall well short of what the research indicates would be effective. Its 600mg of KSM-66 ashwagandha checks that box nicely, but its shilajit and longjack content are both below clinical relevance.

It also contains DIM and quercetin, neither of which boasts enough clinical evidence for us to assume they’d work well for preserving or improving testosterone levels in men. And with Vitality costing $55 for a one-time purchase and $50 for subscribers, you’re not really saving all that much compared to some superior products out there.

Momentous Male Hormone Support

Momentous technically doesn’t have a dedicated testosterone booster complex like the other companies in our guide. Instead, it offers a bundle of two single-ingredient products with good research behind them in testosterone support: tongkat ali and zinc.

The benefit of this approach is that you have a little more control over your dose. Momentous recommends 400mg per day of tongkat ali, and that’s a good path. But it only recommends 15mg of zinc, which may be a little light for some men, especially if low zinc levels are significantly impacting their testosterone production.

With the single-ingredient approach here, you can increase that zinc quantity as you see fit, but it will affect your budget. As it is, these two ingredients from Momentous cost almost as much as the entire bottle of Testosterone Support from Innerbody Labs, which contains the same 400mg dose of tongkat ali, 10mg more zinc, and nine other useful ingredients at clinically relevant doses.

Beyond Alpha Testosterone Breakthrough

There’s an outside chance that this is a great product, but you’d never be able to predict it. That’s because Beyond Alpha has chosen to hide the doses of all of its ingredients in proprietary blends with ridiculous names:

• MuscleSCULPT: 1,000mg
• TestoCHARGE: 904mg
• LibidoRISE: 395mg
• PerformanceBURST: 76mg

MuscleSCULPT contains a 1,000mg combination of ashwagandha and tongkat ali, which could equate to 600mg of the former and 400mg of the latter. That would be consistent with the science. But it could just as easily contain 999mg of ashwagandha and 1mg of tongkat ali. The other blends all follow the same pattern.

Some companies might do this to trick their customers into thinking they’re getting something truly special, a proprietary approach that no other company could match. Other companies do it as a way to control costs, leaning more heavily on less expensive ingredients and massaging the blend doses to reflect the best possible scenario, as with that potential ashwagandha-tongkat ali split.

And Beyond Alpha wants $90 for a one-time purchase or $76 for a subscription. Without your knowing exactly what you’re getting, it’d be unwise to spend the extra money here.

Our lowest tier is reserved for supplements that have significant shortcomings in their formulas, as well as pricing that often doesn't reflect what you should save by making those formulary sacrifices.

We can categorize these in three ways:

• Supplements with decent prices but bad formulas
• Supplements with decent formulas but bad prices
• Supplements with poor formulas and high prices

Let’s break down each subcategory:

Decent price, bad formula: Menerals, JoyMode, GNC

This was the most common type of bottom-tier product in our research. Their formulas are simply lacking, sometimes in the number of ingredients with clinical relevance, sometimes in dose strength, sometimes both. They’re generally as affordable as better options, with some boasting pretty low prices, but none of their discounts could make up for their formula woes.

Here’s a quick breakdown of what fell short in each case:

• Menerals: Good doses of zinc and magnesium alongside an unstudied dose of fulvic acid minerals and too little boron. That’s it.
• JoyMode: Good hits of ashwagandha and boron, with a little zinc, magnesium, and DIM. Not terrible, but thin.
• GNC Mega Men Advanced Testosterone: Cheap, but only five ingredients, and fenugreek is the only one whose dose and inclusion have scientific support.
• Thorne Advanced Testosterone Support: Relevant doses of shilajit and ashwagandha, with a little zinc and luteolin, which lacks sufficient support for testosterone boosting. Rather thin.
• Umzu Testro-X: Decent boron content, but the other nine ingredients either lack support or are dosed too low.
• Life Extension Testosterone Elite: At $36/bottle, it’s cheap enough to almost make you forget it only contains two ingredients, and that only one boasts significant science.
• Testosil: Too much zinc, too little of nearly everything else. Lots of questionable ingredient choices.
• Fling Iron Horn: Points for gummy delivery, but comically low doses of its botanicals. You’re better off with a multivitamin.
• Wolf Tactical Alpha Testosterone: Hands down, worst formula in our guide. Bad ingredient selection, all doses too low.
• Mtn Ops Ox: Tesnor and pine bark doses are on the low side of clinical relevance. All other ingredient doses are way too low.
• Snap Testo Booster: Too much vitamin D, too little of everything else. Several questionable inclusions, such as sarsaparilla root and stinging nettle.
• Irwin Naturals Testosterone Mega Boos RED: Very well-priced but contains absolutely nothing that’s both associated with testosterone and present in a clinically relevant dose.

Decent formula, bad price: Alpha Lion, Nugenix

On the flip side of the coin we just described, you’ll find a few products that have relatively decent formulas, but cost much more than other products that are as good or better. Let’s explore those briefly:

Poor formula, high price: Test Boost Max, TestoPrime, Apex Labs

This is the bottom of the barrel, unfortunately. These products might contain one or two well-dosed ingredients, but these are often limited to a vitamin or mineral you could get for far less without paying out the nose for underdosed botanicals that may or may not work.

Here’s a quick breakdown of our bottom-tier products:

• Test Boost Max: Ten ingredients, and only zinc offers genuine testosterone support at a meaningful dose. All for $50/bottle. Not the worst price, but a very poor value.
• TestoPrime: Too much zinc but way too little of everything else, including less than one-tenth an effective ashwagandha dose. And $65 for one-time purchases doesn’t cut it here.
• GNC Mega Men Ultra: It’s $90 for Tesnor and minimal doses of zinc, D3, and HMB, alongside a half dozen ingredients with little or no proven relationship to testosterone. Not even close to worth it.
• GNC Healthy Testosterone: At $60, it’s a better value than Mega Men Ultra, but its botanical doses are low enough that it’s little more than a glorified multivitamin.
• Apex Labs Primal Drive: Lots of fenugreek, but doses drop off a cliff after that, all for a one-time cost of $100 and a best possible price of $80/bottle.
• Hunter Test: Too much vitamin D and middling doses of only eight other ingredients, all for $90 per month. Bulk options take it down to $68, but that still isn’t worth it.
• Animal Test: After a 600mg dose of ashwagandha, doses fall off and ingredient quality crumbles, with a one-time cost of $84 and a subscription cost of $72.
• TestroVax: This one is $69 for one-timers and $55 for a subscription to a proprietary blend that’s rife with questionable ingredients and too small in its total weight to be effective for its most abundant ingredient.
• Bucked Up Rut: A higher-than-necessary dose of ashwagandha, a high dose of an ED botanical in Tribulus terrestris, too much D3, and too little tongkat ali for $70, or $60 if you subscribe.24

There's a whole subcategory of nutritional supplements, commonly known as male enhancement pills, that may help men with low testosterone or those with associated symptoms. They come from a handful of companies and consist of many ingredients similar to those you might find in a testosterone-targeted supplement.

Most of the ingredients from testosterone boosters that also make their way into male enhancement pills are the ones whose research points toward increased libido and sexual performance. They tend to have fewer studies looking specifically at their relationship to testosterone levels, and doses can often be far below what studies would recommend.

Still, for men with performance issues who suspect they might not have low testosterone, male enhancement pills can offer a well-targeted approach. Here’s a quick look at our top-recommended male enhancement pills:

Performer 8

BEST PRICE: $39/bottle

Performer 8's ingredients are about as close to many targeted testosterone boosters as you'll see among products branded as male enhancement pills, especially after a recent reformulation. It previously contained a 3,000mg dose of muira puama to address ED, but that has been replaced with things like L-arginine, magnesium, and zinc to address both ED and testosterone more comprehensively.51 30

The best thing about Performer 8 is its money-back guarantee. It's a lifetime promise that if you're unsatisfied at any point in the process, you can set up a return and receive a full refund.

Here's a quick look at Performer 8's ingredients:

• Ashwagandha: 750mg
• L-Arginine: 500mg
• L-Lysine: 500mg
• Caffeine: 200mg
• Senactiv: 50mg
• Magnesium: 80mg
• Zinc: 10mg
• Vitamin B6: 1.4mg
• Copper: 1mg
• Vitamin B9: 200mcg

In our estimation, Performer 8 is currently the best male enhancement pill on the market.

VigRX Plus

BEST PRICE: $49.16/month

While many male enhancement supplements rely on studies that focus on individual ingredients, VigRX can boast a study specific to its formulation. Unfortunately, that study looked at a much larger dose of the VigRX formula than what we see in the supplement sold to consumers,31 and the doses found in the commercially available supplement are often subpar compared to research on their individual potentials.

The VigRX formula comprises:

• Damiana: 200mg
• Epimedium leaf extract: 15mg
• Asian red ginseng: 100mg
• Muira pauma bark extract: 50mg
• Tribulus terrestris: 150mg
• Cuscuta extract: 50mg
• Hawthorn berry: 100mg
• Catuaba bark extract: 25mg
• Saw palmetto: 100mg
• Ginkgo biloba: 100mg
• BioPerine: 10mg

You can learn all about the VigRX in our thorough review.

Semenax

BEST PRICE: $33.33/bottle

Semenax has the most extensive ingredient list of any testosterone booster in this guide, with 18 minerals, botanicals, and amino acids that studies show may stimulate testosterone and increase semen production. Here's a complete list:

• Swedish flower pollen: 50mg
• L-arginine HCL: 250mg
• L-Lysine: 250mg
• Epimedium leaf: 150mg
• L-Carnitine: 500mg
• Zinc: 30mg
• Catuaba bark: 200mg
• Maca: 400mg
• Pumpkin seed: 30mg
• Vitamin E: 60IU
• Pine bark extract: 300mg
• Muira puama: 100mg
• Hawthorn berry: 50mg
• Cranberry: 50mg
• Avena sativa extract: 50mg
• Sarsaparilla: 50mg
• Butea superba: 500mg
• Tribulus terrestris: 50mg

The most promising part of this formula is the 30mg of zinc. With the other ingredients, several of the doses are substandard compared to successful small-scale studies.

You can learn more about Semenax in our complete review.

Volume Pills

BEST PRICE: $33.33/month

Fans of Chinese and Ayurvedic medicine will appreciate the combination of ingredients they'll find in Volume Pills. The company certainly is one of many to look at for effective treatments in Eastern medicine, but it goes the furthest to include a wide variety. The downside here is the need for more scientific evidence to support the efficacy of many of its ingredients. But if you prefer botanicals to lab-derived components, it might be a good place to start.

Here's a complete list of Volume Pills’ ingredients:

• Solidin
• Rou Gui
• Ku Gua
• 4,5,7-Trihydroxyflavanone
• Arjuna
• Dong Chong Xia Cao
• Zinc gluconate
• Ling Zhi
• Xian Mao
• Tian Men Dong
• Drilizen
• Fucus vesiculosus
• Hong Hua Fen
• Emblica officinalis

Volume Pills provides the ingredient quantity of its entire proprietary blend per dose, but not for the individual ingredients. We go deeper into Volume Pills' possibilities in our full review.

Male Extra

DISCONTINUED

Male Extra was discontinued by its parent company, Health Nutrition, LTD. Compared to Semenax, Male Extra had a much slimmer ingredient list that included methylsulfonylmethane (MSM), a form of sulfur. Anecdotal evidence suggests a link between sulfur and penis enlargement, but extensive research is still missing from the picture.

More useful was the included pomegranate extract. A pair of studies suggests that pomegranate juice can lead to stronger erections and improved nitric oxide performance.32 33

Here is what Male Extra's whole ingredients list looked like:

• Vitamin B3: 18mg
• Zinc: 14mg
• L-Arginine hydrochloride: 600mg
• Pomegranate extract: 500mg
• MSM: 100mg
• L-Methionine: 100mg
• Cordyceps mushroom powder: 25mg

If you encounter a product calling itself Male Extra online, we recommend that you exercise heightened caution because counterfeit supplement products are not uncommon.

Max Performer

DISCONTINUED

Like Male Extra, Max Performer was recently discontinued. Its ingredients were about as close as you could get to the ingredients in the average testosterone booster. The only things missing were ashwagandha root, D-aspartic acid, boron, and fenugreek. It offered a decent amount of horny goat weed, maca, and zinc, but even when it was readily available, we concluded that there were more effective supplements than what Max Performer offered.

Here’s a closer look at what was inside:

• Horny goat weed: 1,000mg
• Maca: 1,000mg
• Cordyceps: 1,000mg
• Korean red ginseng: 1,000mg
• BioPerine: 15mg
• Selenium: 120mcg
• Zinc: 24mg
• Pantothenic acid: 40mg
• Pyridoxine HCl: 10mg
• Iron: 14mg
• Niacin: 32mg
• Riboflavin: 10mg
• Cyanocobalamin: 10mg
