Mars Men is a men's supplement brand out of Austin, Texas selling a single product: Natural Testosterone Support, a 150-capsule bottle taken five capsules a day. It runs anywhere from $39 to $118 depending on where and how you buy it, and it's sold direct, on Amazon, and on GNC shelves. The brand has been running heavy paid advertising through 2026, which is probably how you heard about it.
If you landed on this page, you're probably weighing whether the formula is real, whether the price is fair, and whether there's something that fits your life better. The short version: the product exists, the label is fully disclosed, and the questions worth asking come down to what's actually in the bottle, what it truly costs, whether you'll realistically take five capsules every morning for three months, and whether a once-a-day morning capsule is the right shape for how your body actually works.
One thing to know before you read further: independent reviews of Mars Men do not all describe the same formula. Ingredient counts and doses differ from one review to the next, and several differ from the supplement facts panel published on retailer listings. We'll show you the panel we verified and where it came from, so you can check it against the bottle you're actually looking at.
Here's the honest rundown.
The Short Answer
Mars Men is a legitimate, fully-disclosed formula with genuinely large botanical doses — but it's subscription-only on their site, and the panel on retailer shelves doesn't match the one on their website.
Is it real? Yes. Every dose printed on the label, no proprietary blends, and the headline botanicals are dosed high — Tongkat Ali and Fenugreek at 1,000mg each. Distributed by Mars Men, Inc. of Austin, Texas.
What should you know before ordering? Five capsules every single morning for at least three months. And on their own site there's no one-time purchase — the only way to buy is a subscription that reorders every 30 days.
Why do reviews disagree? Because there appear to be two panels in circulation. The manufacturer's own page lists nine line items with no Cistanche and no Copper; GNC's listing still shows both, plus different amounts for five other ingredients. Check the label on the bottle in front of you rather than trusting any single review, including ours.
Is there something better for a working man? Depends what you need. Where we differ is timing — hormone support built around your shift and your sleep rather than one morning dose:
- Hammer — pre-bed natural testosterone support
- Overdrive Men's — morning stamina and daytime drive
- N.O. Flow — stimulant-free circulation support
- Rock-Hard Pack — all three, timed across the full day
What Is Actually In Mars Men
Mars Men Natural Testosterone Support comes in a 150-capsule bottle. That's 30 servings, because a serving is five vegetarian capsules taken once daily after your morning meal.
Here is the supplement facts panel as published on the manufacturer's own product page:
| Ingredient | Amount per serving | % Daily Value |
|---|---|---|
| Vitamin D (as cholecalciferol) | 100mcg (4,000 IU) | 500% |
| Vitamin K (as phytonadione) | 100mcg | 83% |
| Zinc (as zinc citrate) | 30mg | 273% |
| Tongkat Ali (Eurycoma longifolia) root extract | 1,000mg | † |
| Fenugreek (Trigonella foenum-graecum) seed extract | 1,000mg | † |
| L-Taurine | 675mg | † |
| Shilajit (Asphaltum) mineral extract | 400mg | † |
| Boron (as boron citrate) | 4mg | † |
| Vitamin K2 (as menaquinone-7) | 100mcg | † |
† Daily Value not established.
Other ingredients: cellulose capsule, goMCT (medium chain triglycerides, gum acacia), microcrystalline cellulose powder, bamboo extract (70% silica).
Credit where it's due. Every active has a stated number next to it and there are no proprietary blends. The brand states the product is made in the USA in a cGMP facility, third-party tested, hormone-free, non-GMO and vegan.
Tongkat Ali at 1,000mg and Fenugreek at 1,000mg are both large amounts relative to what most published human research on those ingredients has used. Whatever else is true, these are not sprinkle doses.
Check The Bottle: Retailer Listings Show A Different Panel
This is worth knowing before you buy, and it's the reason reviews of this product don't agree with each other.
The panel above is what the manufacturer publishes today. Retailer listings show something different. GNC's product page for Mars Men lists a panel that includes Cistanche 500mg and Copper 2mg — neither of which appears on the manufacturer's current label — along with different amounts for Tongkat Ali, Fenugreek, Shilajit, Taurine and Boron.
| Ingredient | Manufacturer's page | GNC listing |
|---|---|---|
| Tongkat Ali | 1,000mg | 500mg |
| Fenugreek | 1,000mg | 500mg |
| L-Taurine | 675mg | 750mg |
| Shilajit | 400mg | 500mg |
| Boron | 4mg | 10mg |
| Cistanche | not listed | 500mg |
| Copper | not listed | 2mg |
The most likely explanation is a reformulation, with retailer listings not yet updated to match. We can't confirm that, and we're not going to guess. What we can tell you is that the manufacturer's own page is the more current of the two, and that a third-party review describing eight ingredients rather than eleven is probably describing the newer formula rather than getting it wrong.
The practical takeaway: read the panel on the bottle you're about to buy. If you're buying at retail, the product on the shelf may not be the formula described on the brand's website. That takes ten seconds to check and it's the only version that matters. It applies to this review too — if the label in front of you differs from the table above, believe the label.
What The Ingredients Actually Are
A label is just a list until you know what's on it. Here's a plain-English pass, without the marketing. If you want to go deeper on the botanicals themselves, we broke them down separately in our guide to herbs for testosterone support.
Tongkat Ali, 1,000mg. Also called Longjack. A Southeast Asian root extract, and one of the most-researched botanicals in the natural testosterone-support category. 1,000mg is at the high end of what published human studies have used.
Fenugreek, 1,000mg. A culinary seed that appears across this whole category, here at a notably large amount. Worth knowing: fenugreek has been associated in some reports with effects on liver and kidney markers. If you take anything containing fenugreek long-term, periodic bloodwork is a reasonable habit. That applies to the category generally, not to this product specifically.
L-Taurine, 675mg. An amino acid. Often associated with energy drinks, but it isn't a stimulant.
Shilajit, 400mg. A resinous substance that seeps from rock in mountain ranges, rich in fulvic acid and trace minerals. It's had a genuine run of research attention over the last decade.
Boron, 4mg. A trace mineral that shows up in most formulas in this space, typically somewhere between 3 and 10mg.
Zinc, 30mg. As zinc citrate, at 273% of the Daily Value. Worth knowing what else you're taking, since zinc appears in most multivitamins too.
Vitamin D, 4,000 IU. A meaningful amount — 500% of the Daily Value. Again, check your existing intake, because plenty of men are already taking vitamin D in a daily multivitamin or on its own, and this stacks on top of that.
Vitamin K 100mcg and Vitamin K2 as MK-7 100mcg. Both forms are included, which is less common than you'd expect. K2 in particular is frequently paired with higher-dose vitamin D.
What's Not In It
Sometimes the absences tell you more than the inclusions:
- No D-Aspartic Acid — a common inclusion in competing testosterone formulas
- No ashwagandha — often used in this category for stress and cortisol support
- No DHEA — good. DHEA is a hormone, banned by most sporting bodies, and a genuine drug-test risk
- No stimulants — no caffeine, no yohimbine
- No creatine or performance actives — this is hormone support only, not an all-in-one
The DHEA absence is the one that matters most. If your job drug tests, hormone precursors are exactly what you avoid, and Mars Men doesn't include any.
Already know what you're after?
If it's the hormone-support piece you want, and you'd rather take it before bed than as five capsules at breakfast, that's Hammer — $42, or $35.70 on subscription. If you want circulation and daytime stamina covered too, the Rock-Hard Pack bundles all three. Both hormone-free and drug-test safe, and both available as a one-time purchase.
What It Actually Costs
Mars Men sells on a subscription-first model, and the headline number is a first-order discount rather than the ongoing price.
| Product | Shipping | |
|---|---|---|
| List price | $118 | — |
| First order (anniversary sale at time of writing) | $39 | Free |
| Every order after that | $59 | Charged |
The $39 is a promotional sale rate, not the standing price. Your refill ships in 30 days at $59, and that's the number to plan around. Skip, pause or cancel any time from your account.
It's a subscription, not a one-time buy
The thing worth knowing before you click, and the reason we're spelling it out: their site doesn't offer a one-time purchase. We checked, and we ordered. The only way to buy from Mars Men directly is to start a subscription that reorders every 30 days.
They disclose this clearly — the product page states that you'll receive a 30-day supply every 30 days and that you can skip, pause or cancel any time. Nothing is buried. But if you were planning to buy one bottle and try it, that option doesn't exist on their site. You'd need to subscribe and then cancel, or buy through a retailer like GNC instead.
Two other things to factor into the real monthly cost:
The $39 is a promotional rate. At the time of writing it's an anniversary sale marked at 67% off the $118 list. Sale prices come and go, and the page itself frames the ongoing subscriber rate as $59. That's the number to plan around, not the sale price.
Free shipping is scoped to the first order. Their page says "Fast & Free Shipping on First Order." Refills aren't covered. We ordered to confirm what that means: the refill invoiced at $59 for the bottle plus $7 standard shipping before tax. Shipping charges vary by location and promotions change, so check your own checkout total.
So the honest ongoing figure is around $66 a month rather than $59, and the first order is the only one where both the sale price and the free shipping apply. That's not a criticism — it's how most subscription supplement brands price, including plenty we'd recommend. It's just worth knowing what you're signing up for rather than budgeting off the number in the ad.
To their credit, the subscription carries a 90-day money-back guarantee — longer than ours at 30 days — plus subscriber gifts on the first order. That's a fair thing to weigh.
The same three questions are worth asking of any subscription-first supplement, ours included: what does the introductory price cover, what does the refill actually bill at, and is shipping included on refills. Those three lines tell you the real cost.
Retail listings run higher — GNC lists the product around $99.99 — though as noted above the retail panel differs from the manufacturer's, so you may not be comparing the same formula. Supplement pricing in this category is heavily promotional and moves fast, so treat every figure here as a snapshot and check before you buy.
The Part Nobody Mentions: Five Capsules, Every Morning
The directions are five capsules once daily after your morning meal, continued for at least three months.
For some men that's a non-issue. For plenty of others, it's the exact reason the bottle ends up half-full at the back of a cabinet.
Think honestly about your actual mornings. If yours is a travel mug and a truck door at 4:45am, five capsules after a breakfast you may or may not eat is a real ask — ninety mornings in a row, minimum, before you're even supposed to judge whether it did anything.
This isn't a knock on the formula. It's the single most under-discussed factor in whether any supplement works for you. The best formula on earth does nothing from inside a closed bottle. Adherence isn't a footnote; it's most of the game.
The Timing Question
Here's something worth understanding before you choose anything in this category.
Male hormone production isn't flat across the day. It follows a daily rhythm, and a meaningful share of the body's natural activity happens overnight during deep sleep. That's simply how the biology is structured.
A once-daily morning capsule is a perfectly reasonable approach to that. It isn't the only one, and it isn't obviously the best one.
It's also worth being blunt about something this entire category glosses over: if you're sleeping five hours a night, no capsule fixes that. Sleep, bodyweight, and alcohol move these numbers more than anything on any supplement shelf. Anyone selling you a bottle as a substitute for those three things is selling you something. We wrote more about that in Reclaiming Your Prime After 40.
How We Approach It At Blue Collar Nutrition
We'll be straightforward: we sell competing products, and you should weigh what follows with that in mind.
Where we differ from Mars Men isn't really the ingredient list. It's the structure. We don't think one capsule taken at one time of day should be asked to cover three different jobs.
The Rock-Hard Pack is three separate products, each taken when it makes the most sense:
- Hammer — two tablets, taken about an hour before bed with a full glass of water. It supports your body's own natural testosterone production during sleep, the window where most of that activity naturally happens. Use the bathroom before you lie down.
- Overdrive Men's — three capsules in the morning after breakfast. It supports natural stamina and steady daytime drive across a long shift.
- N.O. Flow — two capsules, stimulant-free, supporting circulation through L-Arginine and L-Citrulline.
Three products, three timings, covering the full 24-hour cycle instead of a single morning dose. Whether that structure is worth it to you depends on how much weight you give timing. We give it a lot. If you want the reasoning behind how the three were built to work together, we laid it out in the Rock-Hard formula breakdown.
On price: the Rock-Hard Pack is $116.99 one-time, or $99.44 on Subscribe & Save. That's three products rather than one, and it costs more than a single bottle of Mars Men. We'd rather say that plainly than dress it up. Every order is covered by our money-back guarantee.
Every Blue Collar Nutrition product is made in the USA in an FDA-registered, GMP-certified facility, third-party tested, hormone-free, with no artificial dyes.
One thing to know before ordering: Hammer contains oyster extract. If you have a shellfish allergy, don't take it. Full ingredient details are on the Hammer product page.
Will Either Of These Fail A Drug Test?
We can only speak for our own products, and this question matters enormously to our customers — CDL drivers, oilfield crews, military, first responders, and anyone in a safety-sensitive role where one positive result ends a career.
Absolutely not. All products are natural, hormone-free, and do not contain any amphetamines or substances that would trigger a failed drug test — whether for bodybuilding, employment, or any other purpose.
For any supplement from any brand, ours included: if testing is a factor in your work, verify the policy, ask the manufacturer directly, and get the answer in writing. Keep the bottle and the lot number.
So Who Is Mars Men Actually For?
Mars Men is a reasonable choice if you want a fully-disclosed, substantially-dosed herbal formula in one daily serving, you can genuinely take five capsules after breakfast every day for three months, and you buy it on the manufacturer's subscription rather than at retail. The label is transparent and the doses on the headline botanicals are real.
We're probably the better fit if you want hormone support timed to when your body actually does that work, you'd rather build a routine around your shift than around a single morning dose, you want circulation and daytime stamina addressed alongside the hormone piece, or you want a brand built specifically for people who use their bodies to earn a living.
Neither is right for you if you're looking for a bottle to substitute for sleep, or you expect a supplement to do the job a lab result and a doctor should be doing.
Whichever direction you go: get baseline bloodwork before you start, and get it again at 90 days. It's the only way to know whether any of this did what you hoped. No supplement label — ours included — is a substitute for a number on a lab report.

Mars Men Review: Frequently Asked Questions
What are the actual ingredients in Mars Men?
Per the supplement facts panel published on the manufacturer's own product page, one five-capsule serving contains Vitamin D 100mcg (4,000 IU), Vitamin K as phytonadione 100mcg, Zinc as zinc citrate 30mg, Tongkat Ali root extract 1,000mg, Fenugreek seed extract 1,000mg, L-Taurine 675mg, Shilajit mineral extract 400mg, Boron as boron citrate 4mg, and Vitamin K2 as MK-7 100mcg. Note that GNC's retail listing shows a different panel that also includes Cistanche and Copper, so check the label on the bottle you are actually buying.
How much does Mars Men cost?
The manufacturer sells it on subscription: $39 for a promotional first order against a $118 list price, then $59 for every order after that, shipping every 30 days. That works out to roughly $1.97 per serving ongoing. Retail listings run higher, with GNC around $99.99 for a single bottle. Pricing is promotional and changes frequently, so confirm before purchasing.
Can you buy Mars Men without a subscription?
Not on their own website. We checked and ordered to confirm: the only purchase option offered directly is a subscription that reorders every 30 days, though it can be skipped, paused or cancelled at any time and they disclose this on the product page. If you want a single bottle without a subscription, a retailer such as GNC is the alternative.
Is shipping free on Mars Men?
On the first order only. The product page states "Fast & Free Shipping on First Order," so refills are not covered. We ordered to confirm: the refill invoiced at $59 for the bottle plus $7 standard shipping before tax, making the ongoing cost closer to $66 a month. Shipping charges vary by location and promotions change, so check your own checkout total.
How do you take Mars Men?
The manufacturer directs users to take five capsules once daily after a morning meal, and to continue for at least three months for best results. One 150-capsule bottle is a 30-day supply.
Does Mars Men contain proprietary blends?
No. The Mars Men label discloses a specific amount for every active ingredient. There are no undisclosed blends on the panel.
Is Mars Men a hormone or a steroid?
No. Mars Men is marketed as a natural testosterone support supplement made from botanical extracts, vitamins, and minerals. It contains no DHEA and no hormone precursors, and it is not a hormone replacement product.
Does Mars Men contain D-Aspartic Acid?
No. D-Aspartic Acid does not appear on any published version of the Mars Men panel. Reviews that discuss D-Aspartic Acid in connection with Mars Men are noting its absence rather than its presence, since it is a common ingredient in competing testosterone formulas.
Does Mars Men have caffeine?
No. There is no caffeine on the Mars Men supplement facts panel and no stimulants of any kind. The actives listed on the manufacturer's panel are vitamin D, vitamin K, zinc, tongkat ali, fenugreek, L-taurine, shilajit, boron, and vitamin K2 as MK-7. L-taurine is often associated with energy drinks, but it is an amino acid rather than a stimulant and does not act like caffeine. Because the serving is taken in the morning after food, it will not add to your daily caffeine total from coffee or energy drinks.
Where is the cheapest place to buy Mars Men?
The manufacturer's own subscription is the cheapest route — $39 for a first order and $59 for each order after, against roughly $99.99 at GNC. Note that the retail panel and the manufacturer's panel differ, so the two may not be the same formula. Pricing is promotional and changes often, so check before buying.
What is the difference between Mars Men and the Blue Collar Nutrition Rock-Hard Pack?
Mars Men is a single product taken as five capsules each morning. The Rock-Hard Pack is three separate products timed across the day: Hammer about an hour before bed, Overdrive Men's in the morning after breakfast, and N.O. Flow for circulation support. The difference is timing and structure rather than one formula being a version of the other.
How much is the Rock-Hard Pack?
The Rock-Hard Pack is $116.99 for a one-time purchase, or $99.44 with Subscribe & Save 15%. Pricing is current as of publication and subject to change.
Will Blue Collar Nutrition supplements cause a failed drug test?
Absolutely not. All products are natural, hormone-free, and do not contain any amphetamines or substances that would trigger a failed drug test — whether for bodybuilding, employment, or any other purpose.
Are there allergens in the Rock-Hard Pack?
Yes. Hammer contains oyster extract and is not suitable for anyone with a shellfish allergy. Full ingredient details are listed on each product page.
When should you take a natural testosterone support supplement?
It depends on the product. Mars Men directs five capsules in the morning after food. Hammer is taken about an hour before bed with a full glass of water, because a meaningful share of the body's natural hormone activity happens overnight during sleep. Follow the directions on whichever label you are using rather than applying one product's timing to another.
