Muira Puama for Men: What the Research Shows
Muira puama for men is a Brazilian shrub bark sold in sexual-health supplements. We found no human trial of it, so we make no efficacy claim. Reviews call herbal aphrodisiac data sparse. In Stallion Power it is the first blend line, at no more than about 77 mg by our arithmetic.

The plant01
What is muira puama and what does it do for men?
Muira puama is a shrub from the Amazon region whose bark and roots appear in herbal products sold for male vitality.
What it does in men is unproven. We searched and found no human trial of muira puama for any outcome we could cite. A review of herbal sexual enhancers calls the data sparse and warns that interactions worry experts (Brunetti 2020, herbal sexual enhancers (muira puama)).
So the honest answer is "unknown". Old use is not evidence. We make no efficacy claim for it.
On the label02
How much muira puama is in Stallion Power?
The label hides the amount, but the order of the blend sets a ceiling of about 77 mg per gummy.
Muira Puama Extract is the first line of the 82 mg proprietary blend. Single amounts may be hidden, but the parts must run from most to least by weight (21 CFR 101.36 (proprietary blends)). Caffeine is printed as 5 mg and sits fifth, so lines one to four share at least 57 mg.
This is our arithmetic from the label order, not a lab test. The real figure could be far lower. The table shows all nine ceilings. Supplements need no approval before sale (FDA 101: Dietary Supplements), and the sales page cites no studies (Stallion Power sales page). The muira puama and catuaba page goes deeper.
| Place | Label line | Most it can weigh | Why |
|---|---|---|---|
| 1 | Muira puama extract | At most about 77 mg | The first line can be at most everything except the caffeine: 77 mg. |
| 2 | Maca extract | At most about 38 mg | Two lines at least this heavy, so at most half of 77 mg. |
| 3 | Catuaba extract | At most about 25 mg | Three lines at least this heavy: at most a third of 77 mg. |
| 4 | Green tea extract | At most about 19 mg | Four lines at least this heavy: at most a quarter of 77 mg. |
| 5 | Caffeine | 5 mg | Printed on the label: 5 mg. |
| 6 | Ashwagandha | At most about 5 mg | Listed after the 5 mg caffeine, so it cannot weigh more than that. |
| 7 | L-arginine | At most about 5 mg | Listed after the 5 mg caffeine, so it cannot weigh more than that. |
| 8 | Tribulus terrestris | At most about 5 mg | Listed after the 5 mg caffeine, so it cannot weigh more than that. |
| 9 | Horny goat weed extract | At most about 5 mg | Listed last, so it cannot weigh more than the caffeine. |
Lines 1-4 must add up to 77 mg minus nothing else: 82 mg total, less 5 mg caffeine, less at most 20 mg for lines 6-9, leaves at least 57 mg for lines 1-4. This is our arithmetic from the label order, not a lab test. The label also says the blend is equivalent to about 567 mg of dry powders, which describes the starting plant material, not the finished amounts.
Safety03
Who should talk to a doctor before taking muira puama?
Anyone who takes medicine, has a medical condition, or is pregnant or nursing should ask first. The label says the same.
Natural does not mean safe (NIH ODS, Dietary Supplements: What You Need To Know). Keep taking prescribed medicine, and ask a clinician before adding any supplement (FDA, Mixing medications and supplements). Erectile problems can point to heart disease or diabetes, so a doctor visit comes first (Mayo Clinic, Erectile dysfunction). See side effects for stop signs.

FAQ05
Questions about muira puama
Does muira puama help men?
No. We found no human trial of muira puama, so we make no efficacy claim. A review of herbal sexual enhancers describes the data as sparse (Brunetti 2020, herbal sexual enhancers (muira puama)).
What part of the plant is used in supplements?
Products often use bark or root extracts. The Stallion Power label says only "Muira Puama Extract" and does not state the part of the plant or the strength of the extract.
Does Stallion Power list the muira puama amount?
No. It is inside an 82 mg blend. By our arithmetic from the label order, line one is at most about 77 mg. That is a ceiling, not a measured amount (21 CFR 101.36 (proprietary blends)).
Can muira puama be taken with prescription medicine?
Ask your clinician or pharmacist first. Interaction data are limited, and supplements can change how medicines work (FDA, Mixing medications and supplements). Do not stop prescribed medicine on your own.
