Mars Men and Primal Viking are two of the most heavily advertised testosterone support supplements of 2026, and if you've been scrolling, you've probably seen both. They take completely different routes. Mars Men Boost is an herbal and mineral capsule with every dose printed. Primal Viking's Ancestral Testosterone Booster is a reindeer and beef organ blend in a capsule.
Here's how they compare on the label, the real cost of one jar or bottle, the subscription terms and who each one fits. To keep the math fair, we compare one bottle of each, not the multi-jar bundles.
The Short Answer
Mars Men prints every dose; Primal Viking hides most of its formula in a 337.5mg organ blend. They cost about the same, roughly $2 a day on subscription. If you want a fully printed label for less, with no subscription required, look at Overdrive Men's.
What's the main difference? Mars Men is 11 herbs, vitamins and minerals in 5 capsules a day. Primal Viking is a reindeer liver, heart, kidney and beef testicle blend plus four small herbal extracts in 2 capsules a day. Both labels
Which is cheaper? Close to even. Mars Men is $59 for a 30-day bottle on subscription, about $1.97 a day. One jar of Primal Viking is $49.99 on subscription for 24 days, about $2.08 a day. Cost per day
Which one works better? Neither has a published trial on its finished formula. Mars Men's ingredients have more human research behind them; organ meat supplements have very little. Does either work?
Can you buy either one-time? Mars Men has a one-time option at full price. Primal Viking's prices are subscription prices. Subscriptions

What's on Each Label
Mars Men Boost

| Ingredient | Per serving |
|---|---|
| Vitamin D | 100mcg (4,000 IU) |
| Vitamin K (phytonadione) | 100mcg |
| Vitamin K2 (MK-7) | 100mcg |
| Zinc (citrate) | 30mg |

| Fenugreek seed extract | 500mg |

| Boron (citrate) | 10mg |
No proprietary blends. For the full breakdown, including the 2026 reformulation that cut tongkat ali and fenugreek in half, see our Mars Men review.
Primal Viking Ancestral Testosterone Booster
Per 2-capsule serving, from the label on the manufacturer's site:
| Ingredient | Per serving |
|---|---|
| Proprietary blend: reindeer liver, reindeer heart, reindeer kidney, beef testicles | 337.5mg total |
| Rhodiola root extract (10:1) | 33.75mg |
| Sea buckthorn fruit extract (10:1) | 28.75mg |
| Nettle leaf extract (10:1) | 16.87mg |
| Peppermint leaf extract (10:1) | 5mg |
Other ingredients: gelatin capsule and organic rice hulls. The four organ ingredients share one 337.5mg total, so there's no way to know how much of each you're getting. For the full breakdown, see our Primal Viking review.
The difference in one line: Mars Men gives you about 2,800mg of named actives you can check against research. Primal Viking gives you about 420mg, most of it in a blend.
Does Either One Work?
Neither brand has a published clinical trial on its finished formula, so the honest answer comes from the ingredients.
- Mars Men's ingredients have the stronger research base. Tongkat ali has the most human research of the botanicals in this category, mostly small studies, with better results in men who start out low or stressed. Zinc and vitamin D matter most if you're actually deficient. Our guide to herbs for testosterone support covers what the research shows.
- Primal Viking's organ blend has very little human research. Organ meats are nutrient-dense foods, but there's little published evidence that a few hundred milligrams of dried organ powder does anything measurable for testosterone. Its herbal extracts are present in small amounts.
Whichever you try, the only way to know what it does for you is bloodwork before you start and again around 90 days. And no capsule covers for short sleep, extra bodyweight or heavy drinking, which move these numbers more than anything on a supplement shelf. Our guide to how to increase testosterone naturally covers those habits.
What One Bottle or Jar Really Costs
Both brands push multi-jar bundles. We're comparing a single bottle or jar of each, the way most guys try something the first time. Prices below are from each brand's product page, checked November 2026.
| Mars Men Boost | Primal Viking | |
|---|---|---|
| Subscription price, one bottle or jar | $59 (listed against $118) | $49.99 (listed against $125) |
| Days it lasts | 30 | 24 |
| Cost per day | About $1.97 | About $2.08 |
| Cost per 30 days | $59 | About $62.49 |
| Refill shipping | $7 after the first order, about $66 a month all in | Free-shipping badge applies to multi-jar orders; single-jar shipping wasn't shown |
| One-time purchase | $118 plus $7 shipping (checked September 2026) | Prices shown are subscription prices |
Two things to keep in mind. First, both "was" prices ($118 and $125) are list prices almost nobody pays. Second, a 24-day jar means more shipments: about 15 a year for Primal Viking versus 12 for Mars Men, which is why the per-day cost is the fairer comparison than the price per jar.
Subscriptions and Guarantees
Mars Men advertises its $59 subscription as "50% off for life." Free shipping applies to the first order only; refills have invoiced at $59 plus $7 shipping. A one-time purchase is available at the full $118. Its 90-day money-back guarantee covers the first order. Subscription billing is the most common complaint in its customer reviews, so save your confirmation.
Primal Viking runs its pricing through a subscription with a countdown-timer sale banner. On November 4 it read "60% off on subscription is ending" with a timer counting down, but the single-jar price was the same $49.99 we saw in September. It offers a 30-day money-back guarantee.
Whichever you choose, read the checkout carefully, note your renewal date, and cancel before it if you're done.
The Marketing Claims
Primal Viking's product page claims that 94% of users saw higher testosterone, that it "melts man boobs and beer belly," and that it supports joints and the immune system. We couldn't find a published study on the finished product behind those numbers. Treat them as marketing, not results you should expect.
Mars Men's marketing is more restrained, describing Boost as working "four ways" to produce, free, protect and support testosterone. Those are the brand's own claims too, built on ingredient research rather than a trial of the product.
How Overdrive Men's Compares
We sell a competing product, and you should weigh what follows with that in mind.
Overdrive Men's sits closer to Mars Men than to Primal Viking: an herbal and mineral formula with every dose printed. The difference is fewer capsules, a lower price and no subscription required.
| Overdrive Men's | Mars Men Boost | Primal Viking | |
|---|---|---|---|
| Daily serving | 3 capsules after breakfast | 5 capsules after breakfast | 2 capsules with a meal |
| Doses printed? | Yes, every ingredient | Yes, every ingredient | No, organ blend |
| Key actives | Tribulus 750mg, chrysin 75mg, tongkat ali 50mg, epimedium 50mg, saw palmetto 50mg, zinc 30mg, magnesium 200mg | Tongkat ali 500mg, fenugreek 500mg, shilajit 500mg, cistanche 500mg, zinc 30mg, vitamin D 4,000 IU | Organ blend 337.5mg, rhodiola 33.75mg |
| One-time price | $39 (30 days) | $118 (30 days) | Subscription pricing |
| Subscription price | $33.15 (30 days) | $59 (30 days) | $49.99 (24 days) |
| Cost per day, subscription | About $1.11 | About $1.97 | About $2.08 |
Where Mars Men wins: bigger doses of tongkat ali and its other botanicals, plus vitamin D and K2, and a 90-day guarantee on the first order.
Where Overdrive Men's wins: price, three capsules instead of five, and a one-time option at $39 with no autoship to manage.
If you want support around the clock, the Rock-Hard Pack pairs Overdrive Men's in the morning with Hammer, two tablets an hour before bed, and N.O. Flow for circulation. It's $116.99 one-time or $99.44 on subscription. Every BCN order is covered by our 30-day money-back guarantee.
Who Each One Fits
- Mars Men if you want a fully printed herbal formula with bigger botanical doses, you're fine taking five capsules every morning, and $59 to $66 a month fits your budget.
- Primal Viking if you're specifically sold on the ancestral organ-meat idea and only want two capsules a day, knowing most of the formula is in a blend.
- Overdrive Men's if you want every dose printed at the lowest cost per day, with no subscription required.
- None of them yet if you haven't had your numbers checked. Get baseline bloodwork first, and talk to your doctor if you take medication or are on TRT.
