Two disclosed labels, different bets
Mars Men is one of the most heavily marketed names in this category, built around a "starter kit" funnel, an anniversary-sale countdown, and some striking testimonial numbers. Credit where it's due: like Alpha Energy, Mars Men publishes every ingredient and every dose — no proprietary blend. So this isn't a hidden-dose story. It's about ingredient choices, subscription structure, and how the claims are sourced.
The decision
| Proco Alpha Energy | Mars Men Testosterone Support | |
|---|---|---|
| Ingredients disclosed | 9 of 9, every dose on the label | 8 of 8, every dose on the label |
| Price | $99/bottle, 30-day supply | $118/bottle list; discounted price requires a subscription |
| Subscription | Optional — 25% off, cancel anytime | Required to get the discounted price; skip, pause, or cancel after signing up |
| First-order pricing | No teaser pricing — $99 is $99 | Introductory order discounted to $39, then $59/month ongoing |
| Guarantee | 90 days, no forms, no hassle | 90 days, no questions asked |
| Third-party testing | Every batch COA-tested, published | Cites ISO 17025-accredited third-party testing; we couldn't find a product-specific public COA |
Mechanism
Mars Men's eight ingredients, per label: Tongkat Ali 1,000 mg, Shilajit 400 mg, Vitamin K1 & K2 100 mcg, Vitamin D 4,000 IU, Zinc 30 mg, Taurine 675 mg, Fenugreek 675 mg, and Boron 4 mg. Alpha Energy's nine: Zinc 30 mg, Magnesium 200 mg, Tongkat Ali 50 mg, Tribulus Terrestris 750 mg, Horny Goat Weed 50 mg, Saw Palmetto 50 mg, Hawthorn Berries 50 mg, Cissus Quadrangularis 50 mg, and Chrysin 75 mg.
Zinc lands at an identical 30 mg in both formulas — a genuine point of parity, and a foundational mineral for normal testosterone production in men who are even mildly deficient. Fenugreek at 675 mg is one of Mars Men's stronger picks; standardized fenugreek extracts have some of the better-replicated human RCT support in this category for strength and free-testosterone markers. Their Tongkat Ali dose, at 1,000 mg, is far higher than Alpha Energy's 50 mg — but most of the positive human trials on Tongkat Ali used a standardized 100:1 extract in the 200–400 mg range, and Mars Men's label doesn't specify an extract ratio, so the two doses aren't directly comparable on a milligram basis. Shilajit and Taurine are the two ingredients we'd flag: shilajit currently has limited, low-quality human trial depth, which is the specific reason it isn't in Proco's lineup; taurine has minimal direct human evidence for testosterone specifically, though it's reasonably studied for general exercise performance.
Fact check
Mars Men's marketing leans on individual customer numbers: testosterone readings jumping from 620 to 879 ng/dL in three months, from 254 to 861 ng/dL in six weeks, from 198 to 687 ng/dL in eight weeks, and a "225% boost" after coming off TRT. These are self-reported testimonials, not results from a controlled clinical trial of the finished product — we couldn't find a study on their site tying the product itself to outcomes of that size. That doesn't mean the individuals didn't experience what they describe; it means those numbers aren't evidence you can generalize from, and a handful of standard ingredients at these doses would not be expected to move bloodwork that dramatically on their own.
The money table
| Proco Alpha Energy | Mars Men | |
|---|---|---|
| Single bottle, no subscription | $99 | $118 |
| Best available price | $74.25 (25% subscription, optional) | $59/month (subscription required) |
| First order | $99 | $39 (introductory, then reverts to $59/month) |
| Annual, best price | ~$891 | ~$688 (1 month at $39 + 11 months at $59) |
Mars Men figures are drawn from their published pricing and sale terms as of August 2026 — sale pricing and "anniversary" promotions on their site change frequently, so check the current offer before comparing.
On paper, Mars Men is the cheaper option over a year — but that price is locked behind a mandatory recurring subscription, not a one-time purchase. Alpha Energy's discount is opt-in: you can buy a single bottle at full price with no commitment, or subscribe for 25% off and cancel anytime.
Safety & regulatory
We didn't find an FTC action, lawsuit, or major regulatory issue tied to Mars Men in our research. Independent review site SuppCo rates the product 8.19/10 and cites ISO 17025-accredited testing and NSF-certified manufacturing at the facility level, but notes it could not independently confirm several product-specific transparency items (manufacturing standards, testing benchmarks, and certifications for this exact product). We're not asserting anything is wrong here — just noting where our own verification ran out, the same standard we'd want applied to us.
Transparency
Full label disclosure puts both brands in the minority of this category, and that's worth crediting on both sides. Where they differ is sales pressure: Mars Men's site runs an active countdown-timer "anniversary sale" advertising up to 67% off, a common DTC urgency tactic worth treating with the same healthy skepticism we'd apply to any limited-time countdown. Alpha Energy's $99 price and optional 25% subscription discount don't change based on a timer.
Who it's for
Alpha Energy makes sense if: you want to buy once with no subscription commitment, you'd rather not hand over recurring billing to get the advertised price, and you want every ingredient dosed in the range most human trials actually used.
Mars Men might appeal if: you're comfortable with an ongoing subscription in exchange for a lower monthly price, and you specifically want fenugreek and a high-dose Tongkat Ali in your stack.
The verdict
Both companies earn real credit for disclosing every ingredient and every dose — that alone rules out a lot of this category. The actual decision comes down to commitment and cost structure: Mars Men is cheaper if you accept a mandatory subscription and don't mind sale-timer marketing; Alpha Energy costs more up front but never requires you to subscribe to get the fair price.

FAQ
Is Mars Men's "620 to 879" testosterone claim verified?
No — it's an individual customer testimonial, not data from a controlled clinical trial of the product. Treat it as one person's self-reported result, not an expected outcome.
Do I have to subscribe to get Mars Men's advertised price?
Based on our research, yes — the discounted pricing (including the $39 introductory offer) is tied to signing up for a recurring subscription. The regular, non-subscription price is $118.
Does Alpha Energy include Tongkat Ali or Shilajit?
Alpha Energy includes Tongkat Ali at 50 mg. It does not include Shilajit, which currently has limited human clinical trial depth by Proco's own evidence standard.
Which one has the better guarantee?
They're essentially matched — both offer a 90-day, no-questions-asked money-back guarantee. This is a genuine point of parity, not a Proco advantage.
