Mars Men Review: Is Investing in This Testosterone Support Supplement Worth It?

What Is Mars Men?

Mars Men is a daily testosterone support supplement designed for men who want to increase energy, stamina, strength, and hormonal balance without using synthetic hormones. It combines eight ingredients, including Tongkat Ali, Fenugreek, Shilajit, Vitamin D, Zinc, and others, to naturally stimulate the body’s testosterone production.

The formula is third-party tested, hormone-free, vegan, and made in a cGMP-certified facility in the United States. The brand positions Mars Men as an all-in-one replacement for several individual supplements, claiming it can improve physical performance, mental focus, and sexual vitality. According to the company, over 121,000 men have used Mars Men, and 91% of them reported higher energy within the first 30 days.

It is sold through a monthly subscription for $59 per bottle, which includes 150 capsules, equivalent to 30 servings. The company offers a 90-day satisfaction guarantee and encourages customers to use their products for an extended period for optimal results. Each bottle comes with a travel tin and a free testosterone optimization guide.

Mars Men is intended for men over 18 who want a safe, ingredient-focused way to support testosterone naturally. While it promises a wide range of benefits, the real value lies in how well the ingredients are selected, dosed, and backed by evidence, which we’ll evaluate next.

Mars Men Ingredients Analysis

We took a closer look at the key ingredients in Mars Men to assess their effectiveness and relevance for supporting testosterone levels and promoting male vitality. Some ingredients are supported by substantial evidence and are used in therapeutic doses. Others either lack human-based results or present concerns related to effectiveness, safety, or function.

Tongkat Ali (Eurycoma longifolia) – 1,000 mg

Tongkat Ali

Tongkat Ali is a well-researched herbal extract that supports testosterone levels, energy, and fertility. It works by stimulating the release of luteinizing hormone (LH), which signals the body to produce more testosterone.

A 12-week study on Physta (a Tongkat Ali extract) in men aged 50–70 found that the 200 mg dose increased total testosterone levels, improved muscle strength, reduced fatigue, and lowered cortisol levels within two weeks. The 100 mg dose showed minor improvements. Both doses raised DHEA levels. No significant safety concerns were reported; however, the results may not apply to all men.

A 4-week study on Tongkat Ali in 63 moderately stressed men and women found reduced tension by 11%, anger by 12%, and confusion by 15%. Cortisol levels dropped by 16%, while testosterone increased by 37%. These results suggest hormonal and mood changes, though effects may vary between individuals. Mars Men includes 1,000 mg, which is above the therapeutic minimum and may enhance its effectiveness. This dosage aligns with clinical ranges used to support male hormonal balance.

We recommend this ingredient.

According to Sarah Thompson, MPH, RDN -Registered Dietitian

Tongkat Ali is a well-researched herb known for its ability to naturally support testosterone production. The 1,000 mg dosage in Mars Men is aligned with clinical findings that show significant benefits for energy, muscle strength, and overall hormonal balance.

During our research we came across a video by @Physionic that explains the effects of Tongkat Ali.

Zinc (as Zinc Citrate) – 30 mg

Zinc

Zinc is a vital mineral that plays a crucial role in testosterone metabolism, sperm production, and immune function. Studies show that even marginal zinc deficiency can lead to a drop in testosterone.

A study published in the Journal of Nutrition, involving men aged 20 to 80, found that higher zinc levels were associated with higher testosterone levels. In young men, restricting zinc for 20 weeks led to about a 73% drop in testosterone. In older zinc-deficient men, six months of zinc supplementation nearly doubled testosterone levels. This highlights zinc’s importance in supporting healthy testosterone production.

Mars Men contains 30 mg of zinc citrate, a well-absorbed form of zinc. This dosage sits near the upper safe limit for daily intake and is effective for addressing deficiency-related hormonal imbalances.

We recommend this ingredient.

Shilajit (Asphaltum s. Mineral Extract) – 400 mg

Shilajit

Shilajit is a natural resin that contains fulvic acid and trace minerals. It is often included in testosterone formulas for its claimed ability to improve fertility and physical strength.

A study in the Journal of Andrologia tested purified Shilajit in men aged 45 to 55. Taking 250 mg twice daily for 90 days significantly increased total testosterone, free testosterone, and DHEA-S compared to placebo. Levels of reproductive hormones, such as LH and FSH, remained stable. This suggests hormonal changes, though effects may vary among individuals.

However, the key issue is quality. Shilajit must be purified to remove heavy metals and contaminants. Mars Men does not specify whether it uses a patented, purified form. Without this clarity, the ingredient raises safety concerns. Unstandardized Shilajit products have been flagged for containing high levels of lead and other toxins. Without confirmation of third-party purification, we cannot confidently support its use.

We do not recommend this ingredient.

L-Taurine – 675 mg

L-Taurine

Taurine is an amino sulfonic acid commonly found in heart and energy formulations. It helps regulate blood flow, reduce oxidative stress, and support cellular hydration. However, its relevance to testosterone support is limited. Most taurine-related studies focus on cardiovascular or neurological outcomes rather than male hormone function.

A review in the Journal of Nutrients found that taurine may support heart health by helping to regulate blood pressure, improve cardiac fitness, and support blood vessel function. Research also links taurine to potential anti-aging benefits, improved metabolic regulation, and possible support for athletic performance. While promising, most evidence comes from early or mixed studies, so that results may vary.

We do not recommend this ingredient.

Vitamin K (as Phytonadione) – 100 mcg

Vitamin K

Vitamin K is critical for blood clotting and bone metabolism. Mars Men includes Vitamin K1 (Phytonadione), which primarily supports coagulation. However, the form more relevant to testosterone and cardiovascular health is Vitamin K2 (especially MK-7).

A study in the Journal of Lipids in Health and Disease found that feeding rats vitamin K2 (MK-4) for five weeks significantly increased testosterone levels in their plasma and testes. The increase was linked to higher activity of enzymes involved in testosterone production. Vitamin K1 did not show the same effect, highlighting differences between K2 and K1.

We do not recommend this ingredient.

We Tried Mars Men

We Tried Mars Men

One of our team members tested Mars Men for a whole month to see if it lived up to its claims. He had been searching for a supplement to support natural testosterone levels, enhance stamina during workouts, and boost overall energy throughout the day. He was already following a good training plan and eating well, but felt stuck with no new gains in strength or stamina.

He took five capsules every morning with food, just as directed. While the capsules didn’t have a bad taste, taking five at once felt overwhelming. He mentioned it became inconvenient, especially on busy mornings. Since it was in capsule form, there was no issue with mixability. The product didn’t affect appetite or provide any feeling of fullness, so satiety was not a factor.

By the end of four weeks, he noticed a slight increase in drive at the gym and felt a little more focused in the afternoon. However, he didn’t feel a significant improvement in strength, stamina, or performance. He also didn’t experience any side effects. Overall, he described Mars Men as decent but said he wouldn’t personally recommend it due to the high capsule count and lack of a long-term testosterone solution.

Similarly, Adaptophen claims to be the best testosterone support supplement, but to determine if it truly boosts testosterone levels, it’s essential to read an Adaptophen review. Understanding the product’s effectiveness requires a closer look at its claims and user feedback.

Side Effects and Safety

So far, Mars Men does not appear to cause serious side effects for most users. The formula is stimulant-free and does not contain ingredients such as caffeine or yohimbine, which are often associated with jitteriness or energy crashes. Most users tolerate the product well, even with daily use, and there are no standard reports of adverse reactions, such as headaches, nausea, or dizziness.

That said, Mars Men may not be suitable for everyone. Ingredients such as Shilajit and Fenugreek can sometimes interact with medications used to treat blood pressure, diabetes, or hormonal imbalances. It is best to speak with a healthcare provider before starting this supplement, especially if you are taking prescription medication.

Mars Men is intended for adult men only. It is not recommended for women, children, or individuals managing a chronic health condition without medical advice. Taking the capsules with food and water may help minimize minor side effects, such as stomach discomfort or indigestion.

Mars Men Real Customer Reviews

To better understand how Mars Men performs for real users, we looked at available customer feedback on independent platforms. While many testosterone supplements rely heavily on marketing, we focused on verified reviews and star ratings. Mars Men does not currently have a visible listing on Amazon, so we turned to Trustpilot for more reliable feedback.

On Trustpilot, Mars Men has received a strong overall score, with many users giving the product 4 to 5 stars. Customers often mention improvements in physical energy, gym performance, and recovery. Others appreciate the all-natural formula and consistent packaging. However, not all reviews are positive. Some users felt underwhelmed by the results or raised concerns about customer support during the refund process.

A top positive review comes from Seth Pahmeier, who rated the product 5 stars. Here’s what he had to say:

Increased T-support naturally! I've tried other products, but I never saw a difference that lasted. Happy to say that Mars Men has been amazing, from energy in the gym to just overall recovery. Awesome to know it's all natural ingredients too!

On the other hand, not all experiences were as positive.

A critical review was provided by Philip Hawkins, who rated the product 1 star. He wrote:

Didn't work for me, no refund.” I wanted to discontinue TRT and transition to a more natural approach. I tried the product for just under 90 days, just in case I needed a refund. I got my labs back and made it to a whopping 132. I reached out and let them know, but I still haven't been able to do that because it errors out every time I try. No testosterone benefit and no reliable customer service.

Is Mars Men Scam or Legit?

Mars Men is not a scam. The supplement is manufactured in a cGMP-certified facility, utilizes clearly labeled ingredients, and is accompanied by a 90-day satisfaction guarantee. The formula includes ingredients like Tongkat Ali and Zinc, both of which have some scientific backing for testosterone support. It’s also third-party tested and openly lists its dosages, which most scam products avoid.

That said, being a real product doesn’t mean it works for everyone. Some users report no noticeable results, and others have shared frustration with the refund process and customer service. While the brand makes bold claims about energy, strength, and testosterone, not all customers experience those outcomes.

If you’re expecting dramatic results or fast changes, you may be disappointed. It’s a legitimate supplement, but the effects are not guaranteed. Also, based on feedback, some users walk away feeling like it didn’t live up to the hype.

Where to Find the Best Value

Mars Men is only available for purchase through the official website. It is not currently sold on Amazon, eBay, or in any retail stores. The product operates on a subscription model, where buyers receive one bottle (containing 150 capsules) every 30 days.

Here are the pricing options:

• 1 Bottle – $59.00/month
• Bundle deals bring the price down to as low as $30 per bottle.

Compared to other male enhancement supplements, Mars Men is on the expensive side, especially since it requires five capsules per serving. While the company offers free shipping and bonuses, such as a travel tin and guide, buyers should weigh the cost against other available options.

Mars Men Vs Flawless Bloom’s PeakErect

Mars Men contains eight ingredients, including Tongkat Ali, Zinc, Shilajit, and Fenugreek, with a focus on testosterone support, energy, and strength. Each bottle contains 150 capsules, which are required for five capsules per serving. It is priced at $59 per month on a subscription, with bundles lowering the cost to $30 per bottle; however, this still places it on the higher end of the market. Some ingredients in Mars Men are well-researched, while others offer limited testosterone-specific support.

In contrast, Flawless Bloom’s PeakErect delivers a broader range of male virility support, sexual support ingredients like Longjack, Maca, Boron, L-Arginine, and a full Ginseng blend. The formula includes 16 active ingredients, eliminating the need for a high capsule count. Pricing is more flexible, starting at $68 for one bottle, or as low as $42.50 per bottle with the six-month bundle. For a better variety of ingredients and more competitive pricing, PeakErect stands out as a more effective option.
