The Best Testosterone Booster in 2025

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 men can nonetheless experience some of those same 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:

Though we don't consider it the best testosterone booster, TestoPrime is also great and makes a solid alternative to our top recommendation. Several well-dosed ingredients, a proven track record, and a lifetime guarantee help to differentiate it. With a formula that contains 12 clinically studied ingredients, it’s designed to increase muscle strength, build endurance, reduce stress, and leave you feeling overall energized. While we wish it provided more ashwagandha, TestoPrime delivers good amounts of zinc, vitamin D, and D-aspartic acid, as well as a meaningful amount of fenugreek. Plus, this testosterone booster ships internationally.

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 (for instance, the runner-up featured above, or Roman's Testosterone Support supplement), 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 the scientific research.

We found ourselves wishing to find 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 comes from our own company. It is 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. 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, and there could be negative consequences if a product is too good at elevating your testosterone levels. 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: Innerbody Testosterone Support

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’re confident that Innerbody's approach offers you the best odds of seeing 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.

TestoPrime presents a reasonably sized combination of ingredients that may boost total or free testosterone, and its doses consistently beat out much of the competition. While one of TestoPrime's most abundant ingredients (D-aspartic acid) suffers from a lot of contradictory and inconclusive research in humans, its supporting players — ashwagandha, zinc, and vitamin D — can step in should the D-aspartic acid not work for you. We wish it contained more significant doses of ashwagandha and fenugreek.

Roman's Testosterone Support supplement also 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.

Here’s a quick look at how ingredient bills compare among the top testosterone boosters on the market.

As you can see, the only product that comes close to matching Innerbody's combination of ingredients and clinically relevant doses is Nugenix, but its Total-T MAXX costs nearly $100 more per bottle. TestoPrime and Roman still have a lot to offer, though, including high doses of zinc. Ultimately, we consider TestoPrime to be our runner-up for efficacy thanks to its zinc dose, 2,000mg of D-aspartic acid, and inclusions of fenugreek and black pepper extract.

Safety

Winner: Innerbody Testosterone Support

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 Innerbody’s Testosterone Support. 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, Innerbody's and Roman’s are the only two 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, but TestoPrime isn’t far behind. Here’s why:

• Roman offers its products on a subscription-only basis for an outstanding price.
• TestoPrime builds savings into its bulk purchasing options, but you’d need to subscribe to bring the cost per bottle down toward Roman’s.

Roman's system 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.

TestoPrime comes very close to Roman’s cost advantage with its five-month supply, which is advertised as a three-month supply with two months for free. That works out to $39/month. The downside there is that you have to spend $195 upfront. You can add automatic renewal to that plan and bring the price down to $166, or $33/month.

For the record, a similar subscription model for Innerbody’s 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. Roman also sends you its product in a refillable glass jar, and subsequent orders arrive in recyclable pouches.

Close to 95% of testosterone is produced by the testicles. "The other 5% is produced by our adrenal glands," explained 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, and 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," said Dr. Urdaneta.

We also spoke to Reda Elmardi, a certified strength and conditioning specialist, registered dietitian, and owner of The Gym Goat, who told us low sex drive is at the top of the list. "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 added, "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. The LetsGetChecked Male Hormone Test may be the best, as it includes an analysis of SHBG levels.

In our opinion, the best testosterone booster currently on the market is Innerbody’s Testosterone Support. 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. This product edges out our prior top pick, TestoPrime, because of its inclusion of tongkat ali and its superior doses of fenugreek and ashwagandha. Innerbody chose these ingredients based on the quality and quantity of available research supporting their efficacy in raising testosterone levels.

TestoPrime does include D-aspartic acid, which Innerbody’s supplement lacks. But we’ve seen conflicting evidence about the effectiveness of that ingredient. At some doses, it appears effective, while it’s been shown to reduce testosterone levels at other doses.4 5 TestoPrime’s 2,000mg of D-aspartic acid lands in what should be a safe place, at least according to those studies, but including a similar dose was a risk we didn’t feel was justified.

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.

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 supplement 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 zinc and boron have been shown to increase free testosterone.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 which 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, but 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, especially gels and creams that 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. 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 TestoPrime and Roman, both of which cost less.

But Innerbody includes useful ingredients you can’t find in those testosterone boosters; for instance, Roman lacks fenugreek and tongkat ali (longjack). Additionally, competitors' doses don't always meet the level that scientific research would suggest they should; though it uses KSM-66 branded ashwagandha, TestoPrime’s quantity of ashwagandha 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 or 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 so doing, 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 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: 2,000mg42
• 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 — 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.

Innerbody Testosterone Support pricing

We’ve adopted 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 from Innerbody is always free, and there’s a 30-day money-back guarantee in place to protect your purchase. For many people, Testosterone Support will ship and arrive in a single day. We don’t ship outside of the U.S. at this time, but that will likely change in the near future.

Overall runner-up

Owing to high zinc and vitamin D quantities alongside branded KSM-66 ashwagandha and fenugreek, TestoPrime had long been a top recommendation of ours among testosterone booster supplements. Its total ingredient profile is commendable for its price point, and it continues to have one of the larger doses of D-aspartic acid among its competitors, but without more concrete science around the substance, it's not the determining factor in our recommendation here. Instead, TestoPrime’s zinc, ashwagandha, and vitamin D quantities are more indicative of its potential.

The presence of branded ashwagandha means that you can be confident in its potency, but we would like to see more of it in the formula. Similarly, based on research, we think the 4:1 fenugreek extract could be reliably meaningful to more men if the 200mg amount were increased by at least 50%. Still, measured against the field of competitors, TestoPrime offers one of the best ingredient bills available. Increasing the KSM-66 ashwagandha and fenugreek while also introducing copper (as a safeguard with this much zinc included), in our opinion, would improve TestoPrime.

Here are the ingredients that make up TestoPrime:

• D-aspartic acid: 2,000mg
• Panax ginseng: 40mg
• Ashwagandha extract: 55.67mg
• Fenugreek: 200mg
• Green tea extract: 200mg
• Pomegranate extract: 8mg
• Vitamin D: 26.68mcg
• Zinc: 40mg
• Vitamin B6: 5.6mg
• Vitamin B5: 8mg
• Garlic extract: 16mg
• Black pepper extract: 6.68mg

We appreciate that TestoPrime lists clinical studies at the bottom of its main page. This helps shed light on the safety and efficacy of its ingredients, but it's noteworthy that so few of the cited studies were conducted on humans (a reminder that there’s much room to improve on the research into these substances). It's also safe to assume that the company would choose the studies that show the greatest degrees of both efficacy and safety, regardless of the study population or other parameters. After all, most of the site’s visitors probably aren't researchers or statisticians.

TestoPrime recently added a chat feature to its website, which is relatively fast and connects you to a human on the other end. We had some trouble getting the representative to answer some of our more nuanced questions, but they were mostly very helpful. Only Performer 8 — our top male enhancement product for testosterone — has a similar chat feature. This doesn't come as too big a surprise; both TestoPrime and Performer 8 share a parent company (Wolfson Brands).

TestoPrime pricing

TestoPrime is available in three different purchasing tiers, each of which also offers a subscription option. Here's how the pricing breaks down:

Shipping is free at every level, and bulk purchases come with e-books about nutrition and exercise.

TestoPrime's confidence in its product is expressed in a lifetime guarantee. This length of time won't be necessary for most men, as you'll know within a month or two whether the testosterone booster is working. TestoPrime will return your entire investment (minus shipping and handling) if its product doesn't work for you. Other companies also offer compelling guarantees, by the way, including lifetime guarantees from Test Boost Max and Performer 8.

TestoPrime vs. Testogen

TestoPrime and Testogen have a lot of similarities. For example, they both offer relatively high doses of well-researched testosterone-boosting ingredients.

However, there are some crucial differences in the ingredient lists that lead us to favor TestoPrime over Testogen. Ultimately, TestoPrime includes more of the better-researched testosterone-boosting ingredients. You could theoretically make up for the difference — and even get a better overall effect — by taking both Testogen's capsules and its drops, but that combination gets expensive.

Here's a handy chart that breaks it down:

In a head-to-head between Testogen and TestoPrime, you can see the latter comes out on top. Innerbody Testosterone Support outmatches either of them when it comes to the inclusion of the best-researched ingredients for testosterone.

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:

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

The strength of that third offering is why Roman earns a place as a top recommendation in this guide. If you are on a tighter budget, we believe Roman Testosterone Support could very well be your best option. In fact, if Roman would adopt a branded ashwagandha like KSM-66, which carries with it a guarantee of potency, this testosterone booster would surpass TestoPrime as our runner-up recommendation without question.

Previously, 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 already have a comprehensive review of the best at-home testosterone tests, and this test from Roman gives several of our top picks a run for their money in both cost and convenience.)

NOTE: In 2024, due to an ongoing clomiphene citrate shortage, Roman temporarily suspended its testing and prescription services for testosterone. We'll continue to monitor the situation and update this page as Roman brings 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.)

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. "After 50 years, there is no variability with testosterone secretion," Dr. Urdaneta told us, "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 just about average 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 recently updated the ingredient bill 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 brings 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 Testosterone Support is the only other T booster in its class providing copper along with zinc.

Roman Testosterone Support pricing

Your first order from Roman will come with a jar capable of holding a month's worth of testosterone support. Subsequent shipments will arrive in pouches that you tear open and use as refills for your jar. This is a nice way for the company to save a little money on packaging, keep shipping costs low, and help protect the environment.

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 Hone Health for a similar treatment experience and pay just $63/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 about the issue, Roman states 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 testosterone booster for ED

Nugenix offers more than a dozen products targeting men's health. Among its testosterone boosters, the company makes a point to employ ingredients that studies associate with free testosterone rather than total testosterone. Many of the formulas contain high doses of ingredients that perform well in studies, but too many high doses can also increase the risk of adverse reactions, especially when they're combined in a single supplement.

We believe Nugenix is a brand worth considering if you’re hoping a testosterone booster will help address mild ED. Specifically, we recommend you consider its Ultimate formula.

Nugenix Ultimate isn’t the most potent testosterone booster in the company’s lineup, but if your testosterone concerns arise from erectile performance issues, it may be a better route than others. That’s because it contains a high 625mg dose of Epimedium sagittatum, or horny goat weed. Studies have shown that icariin, the active constituent of horny goat weed, can recover erectile function, at least in rats.50

If you can afford it and are comfortable with a higher side effect risk, you could stack Nugenix products together, as their ingredients complement one another and would provide you with a complete approach to testosterone boosting.

Here are the ingredients for Total-T Maxx:

• 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

And here’s what makes up the Ultimate formula:

• D-aspartic acid: 3,000mg
• Fenugreek extract: 700mg
• Epimedium extract: 625mg
• Stinging nettle extract: 300mg
• Maca extract: 200mg
• Eurycoma longifolia extract: 150mg
• Mucuna pruriens extract: 125mg
• Boron: 10mg

The 10mg of boron in Nugenix Ultimate is right in line with the dose used in one prominent study.21 Ashwagandha, fenugreek, and D-aspartic acid also appear in clinically relevant doses. The addition of 5mg black pepper extract should increase bioavailability and, by extension, efficacy.

Compared to these ingredient bills, Innerbody Testosterone Support is the closest thing you’ll find on the market, and it costs a lot less. It’s also suitable for vegetarians, which Nugenix products are not (they contain gelatin).

Nugenix pricing

Nugenix may struggle to compete due to higher prices, but it has some of the most potent ingredient profiles on the market. We've identified its top total testosterone and free testosterone boosters as the best options for you:

• Total-T Maxx: $169.99 per bottle
• Ultimate: $89.99 per bottle

Nugenix has a reliable return policy, but the process is a little more complicated compared to other companies. It changes depending on what kind of order you’ve placed. For any automatic shipment order, you get a 30-day money-back guarantee under which you'll have to pay for return shipping, but you can send back an empty bottle. One-time orders are only returnable if they're unopened, but you get 90 days to make the decision.

Ultimately, the return policy is similar to what you'll find with competitors, though the money-back period is shorter than several other options. What's frustrating is that the website buries the relevant information in its terms of service, with no direct link to a money-back guarantee or return policy (which many competitors link to clearly).

Nugenix vs. TestoPrime

Nugenix has some of the best testosterone boosters on the market, with formulas that include a higher number of well-studied ingredients provided at higher doses than you’ll find in TestoPrime’s formula. But TestoPrime may still be effective enough for many men, and it’s significantly less expensive than offerings from Nugenix. The price of Nugenix supplements prevents them from being top recommendations.

Innerbody Testosterone Support occupies a nice middle ground between the two. It delivers a more comprehensive ingredient bill than TestoPrime at a price that’s more favorable than Nugenix.

Easiest to take (drops)

With its drops, Testogen offers one of the more interesting testosterone boosters on the market. They work best when you combine them with the company's capsules; the drops on their own aren’t particularly strong. If your test results show that your testosterone levels are on the low side of normal, something as light as these drops might be an excellent place to start because they're easy to take and shouldn't lead to any overcorrection.

The drops also contain L-arginine, which many studies have examined as an alternative treatment for ED. In some ways, its action resembles that of a PDE5 inhibitor like Viagra or Cialis (prescription ED medications), albeit with a much less significant effect.51

That doesn't mean you should neglect Testogen's capsules, however. They offer a dose of D-aspartic acid at the upper end of what's been shown effective in studies. Some research points toward a decrease in testosterone levels at doses above this, so men with lower BMIs might not benefit from it as much. You also get 50mcg of vitamin D, which is pretty close to what studies often use to increase testosterone.22

Here’s what you’ll get in each Testogen capsule:

• D-aspartic acid: 2,352mg
• Fenugreek extract: 40mg
• Vitamin D3: 50mcg
• Zinc: 10mg
• Korean red ginseng extract 4:1: 40mcg
• Boron: 8mg
• Nettle leaf extract 4:1: 40mg
• Magnesium: 200mg
• Vitamin B6: 20mg
• Vitamin K1: 20mcg
• BioPerine 95% piperine: 5mg

Compare that to the ingredient list for the Testogen drops:

• L-arginine: 500mcg
• Zinc: 1.5mg
• Vitamin D3: 0.75mcg
• Epimedium sagittatum
• Pfaffia paniculata
• Korean ginseng root
• Moringa oleifera

Note: Testogen isn’t forthcoming about all of the ingredient amounts in its drops. The company uses a proprietary blend — a practice that other testosterone boosters in this guide refrain from, as it obscures doses. It's unfortunate. Based on the low amounts of zinc and vitamin D in the drops, it's perhaps safe to assume the other ingredients appear in low amounts. It would be best to think of the drops primarily as a source of L-arginine, though if that’s the case, you could potentially save money by opting for a standalone L-arginine supplement to stack with Testogen capsules.

Testogen pricing

Testogen recently revamped its price structure, eliminating bulk discounts and relying instead on a progressive savings model that gives you a steeper discount the longer you stay subscribed to the product:

Testogen offers a 100-day return policy if you aren't completely satisfied, but it'll charge you a $15 "fixed claim fee," which the company says covers administrative costs. It'll also only accept returns on your first order.

Testogen vs. Nugenix

Compared to Testogen, Nugenix has a lot more products to offer. Many of them are testosterone boosters, but Nugenix also sells supplements for prostate health, fat loss, and cellular maintenance. Nugenix Ultimate is the closest product to Testogen capsules, with a nearly identical ingredient list, though Nugenix doses are much higher. The most striking difference between the two is price. Whereas Testogen capsules cost $59.99 for a one-time purchase and as little as $36/bottle in subscription orders, Nugenix Ultimate costs $89.99/bottle.

From a pure testosterone-boosting perspective, Innerbody Testosterone Support should outperform either of these products. It’s definitely less expensive than Nugenix, though long-term Testogen subscribers may be getting a pretty good deal if its lower doses are enough to work for them.

Test Boost Max relies on some familiar ingredients to boost testosterone, but it also has a handful that you won't see in too many other products. Central to its formula is Tribulus terrestris, which is the subject of much controversial research.23 A recent review didn't completely debunk its potential for use as an aphrodisiac or sexual performance enhancer, but it did call into question Tribulus terrestris' commonly accepted mechanism of action.24 That doesn't mean it's ineffective, but we have a long way to go before we fully understand its potential.

Test Boost Max also used to use KSM-66 ashwagandha, which is one of the better ashwagandha extracts on the market, and its 600mg dose aligned well with studies looking into its testosterone-boosting and mood-regulating effects. You’ll see the same dose of the same branded ashwagandha extract in Innerbody Testosterone Support and Nugenix Total-T Maxx.

Unfortunately, the company has recently reduced its ashwagandha dose from 600mg to just 150mg and stopped using the branded KSM-66 extract. That’s a significant blow to the product's potential efficacy. To make up for this, the company boosted its longjack dose from 20mg to 200mg, but that’s not quite enough to make up for the loss of a high-quality, clinically dosed ashwagandha.

Other than the Tribulus terrestris, longjack, and ashwagandha, much of Test Boost Max's ingredient profile is substandard. It uses ingredients with only a few small-scale studies supporting them, and it does so with doses often lower than those used in research.

Here's a look at the ingredients list:

• Tribulus terrestris: 500mg
• American ginseng root: 20mg
• Cordyceps mushroom: 20mg
• Ashwagandha root extract: 150mg
• Hawthorn berry extract: 40mg
• Longjack root: 200mg
• Epimedium: 160mg

Of the ingredients listed, only Tribulus terrestris and longjack appear in doses we would consider likely to be effective.

While the ingredient list may not be as impressive as others, the company does offer the protection of an excellent return policy. It gives your money back as part of a lifetime guarantee for single-bottle purchases or the first bottle of a bulk purchase when you return the unopened bottles along with it. If you consume more than one bottle from a bulk purchase, you will only get reimbursed for one opened bottle and any unopened bottles.

Test Boost Max pricing

Test Boost Max offers discounts on bulk orders, with a subscription option available for monthly single-bottle deliveries. Here’s how the one-time prices work out:

• One-month supply: $49
• Three-month supply: $132
• Six-month supply: $195

The subscription model sends one month's supply to your home every 30 days for $41/month. That's better than the per-bottle price at the three-bottle bulk level but not as good as the per-bottle price if you purchase six bottles all at once.

For additional savings, you can take advantage of our discount and take 25% off sitewide using the code SCULPTTB25.

Test Boost Max vs. Nugenix

At this time, the only reasons you might prefer Test Boost Max are that it includes Tribulus terrestris — which you'll rarely see in a Nugenix supplement — and that it costs a lot less. The price gap grows if you buy multiple bottles of Test Boost Max, which can end up costing you just one-third of the prices you'll see from Nugenix.

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 booster 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 Hone Health.

Best prescription treatment provider

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. Depending on what you need from Hone, the Premium membership may well be worth it. Even if all you’re getting is testosterone treatment, the fact that a Premium membership covers the costs of initial and quarterly blood tests is significant.

Your test will look at the following biomarkers:

• Total testosterone
• Free testosterone
• Albumin
• SHBG
• LH
• Estradiol
• ALT
• AST
• Prolactin
• Prostate-specific antigen (PSA)
• Hematocrit

Your consulting physician will make recommendations based on your results, with numerous treatments for low T available.

Hone Health pricing

You'll have to pay for your medication in addition to initial consultation and membership prices, but the membership includes free retesting of your testosterone levels every 90 days. Monthly medication costs start as follows and may increase in price with increased doses:

• Testosterone cypionate injectable: $28/month
• Testosterone cypionate topical cream: $60/month
• Testosterone cypionate sublingual troche: $60/month
• Anastrozole: $22/month
• Clomiphene citrate: $38/month
• Supplemental thyroid hormones (T3 and T4): $15-$52/month

For men interested in clomiphene or enclomiphene, the most direct parallel to Hone is Strut Health, which offers testosterone testing and enclomiphene citrate for a fair price.

Between the price of a Premium membership and the cost of clomiphene, Hone's program costs $198/month compared to Strut's free membership model with a $79-$119 range of medication costs. But you could pay as little as $63/month through Hone if you’re willing to get tested elsewhere and import your results. That could make it the better route for certain men, especially if you're interested in trying different TRT methods, as Hone offers several.

Here's a quick comparison between Hone and Strut:

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. A 3,000mg dose of muira puama gives it the potential to address ED while many of its other ingredients work to raise testosterone.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: 500mg
• Maca root extract: 30mg
• Muira puama: 3,000mg
• Ferrous bisglycinate: 12mg
• Panax ginseng: 6,000mg
• Barrenwort: 1,000mg
• Pine bark extract: 300mg
• Glucuronolactone: 600mg
• Grape seed extract: 30mg

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 consumer-facing supplement are often subpar compared to research into 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

CURRENTLY DISCONTINUED

Male Extra was recently 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 study 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 erections32 and improved nitric oxide performance.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

CURRENTLY 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
