Stallion Power Ingredients Explained: What Is in the Blend and What the Research Says
Ingredient lists are where supplement marketing and supplement science meet. This guide reads the label of Stallion Power line by line, does the dose arithmetic the label avoids, and compares each ingredient with the published human research. It is a reading aid, not medical advice, and it does not say the product works.
Step 1. The label, as printed
This is what the Supplement Facts image on the seller's page shows. We read it directly from the label image on October 12, 2026.
| Line on the label | Amount |
|---|---|
| Serving size / servings per container | 1 gummy / 30 |
| Calories | 10 |
| Total carbohydrate (of which sugar 3 g, all added) | 3 g (1% DV; added sugar 6% DV) |
| Sodium | 4 mg |
| Proprietary blend (equivalent to about 567 mg of dry powders, per the label) | 82 mg |
| Listed inside the blend, in order | Muira puama extract, maca extract, catuaba extract, green tea extract, caffeine (5 mg), ashwagandha, L-arginine, Tribulus terrestris, horny goat weed extract |
| Other ingredients | Corn syrup, cane sugar, water, apple pectin, sorbitol liquid, natural flavors, citric acid, sodium citrate dihydrate |
By law, ingredients inside a blend are listed from most to least by weight, so muira puama is the largest and horny goat weed the smallest. That is the only ordering information the label gives. The "567 mg" note describes the amount of raw plant material said to be used to make the extracts, not how much of any herb you swallow.
Step 2. The dose arithmetic
What the label allows
82 mg blend, minus 5 mg caffeine, leaves 77 mg for eight ingredients. Caffeine is listed fifth, so if the descending-weight order is accurate, the four ingredients listed after it (ashwagandha, L-arginine, Tribulus, horny goat weed) are each present at 5 mg or less.
What a trial used
A 12-week ashwagandha trial in adults aged 40 to 75 used 200 mg of root extract twice a day, or 400 mg daily. Even if all 77 mg were ashwagandha, that is about one fifth of the trial dose, and if the label order is accurate, the real figure is 5 mg or less, about 1 percent.
Caffeine in context
The FDA cites 400 mg a day as an amount not generally linked to negative effects for most adults, and a 12-ounce brewed coffee often holds 113 to 247 mg. Five mg is roughly 2 to 4 percent of one cup.
Gummy limits
A gummy base also holds sugar and pectin, so there is only so much room for actives. That is not a flaw in itself, but it means gram-sized doses are not possible in one gummy.
We checked trial doses where the abstract states them. Where it does not, we say so rather than guess.
Step 3. Ingredient by ingredient
The evidence labels used below: Limited human data means a few small trials or reviews that call for more research. Mixed means trials exist but findings are inconsistent or apply to other groups. Lab only means we found cell or animal work and no human trials. These are our plain-language summaries, not formal grades.
| Ingredient | What the seller's page says | What published research says | Level |
|---|---|---|---|
| Muira puama | "Potency wood", traditionally used for energy, stamina and libido. | In our PubMed search the results were laboratory or animal studies. We did not find a human trial. Much of the online enthusiasm traces to patents and tradition, which are not clinical evidence. | Lab only |
| Maca | An adaptogen traditionally used for vitality and drive. | A 2010 systematic review found four small randomized trials and called the evidence "limited", too small to draw firm conclusions. A 2025 meta-analysis of herbal supplements for erectile dysfunction said evidence for maca remains insufficient. | Limited human data |
| Catuaba | Named as an extract in the blend. | Our search surfaced lab studies (for example antimicrobial work on the bark). No human trials found. | Lab only |
| Green tea extract | Named as an extract in the blend. | No sexual-function claim is supported by what we found. Safety note: the NIH's NCCIH says liver injury has been reported, mostly with concentrated extracts in capsule or tablet form. | Not studied for this goal |
| Caffeine (5 mg) | "A touch of natural caffeine". | A mild stimulant. At 5 mg it is far below a cup of coffee. Any alertness effect from this amount would be small. | Well known |
| Ashwagandha | Named as an extract in the blend. | One 12-week randomized trial of 400 mg a day in stressed, tired, overweight adults found reduced fatigue versus placebo on one scale, no difference in perceived stress, and higher free testosterone in the men. NCCIH calls evidence for testosterone limited, says short-term use (up to 3 months) may be safe, and reports rare liver injury. | Limited human data |
| L-arginine | An amino acid the body uses to make nitric oxide, "commonly included to support circulation". | A 2024 network meta-analysis found general ineffectiveness of most nutraceuticals for erectile dysfunction, with some usefulness for L-arginine, mainly alongside prescription ED medicine in men with an organic cause. Trial doses are typically in the gram range, far above what fits in this blend. | Mixed |
| Tribulus terrestris | "Time-honored" herb for stamina and drive. | A 2025 meta-analysis of eight randomized trials in men with erectile dysfunction found higher questionnaire scores than placebo, with no difference in total testosterone. The trials were small and tested men with ED, not healthy men with low energy. | Mixed |
| Horny goat weed (Epimedium) | Long featured in traditional formulas for blood flow and performance. | A 2026 review called the preclinical findings compelling but said robust clinical evidence is still lacking. Published case reports describe liver injury and muscle damage in people using it. | Mostly lab data |
What the studies cannot tell you about this gummy
- Different product, different dose. A trial of a standardized extract at a known dose says nothing about a different extract at an unknown dose.
- Different people. Most erectile-function trials enroll men diagnosed with ED. Few test healthy men who simply feel tired.
- Different combinations. No trial we found tested this exact nine-ingredient mix. Combinations can behave differently from single herbs.
- Small and short. The ashwagandha trial ran 12 weeks; the maca review pooled four trials. Both authors ask for larger studies.
The herbs with the clearest positive signal in the 2025 herbal-supplement meta-analysis for erectile function were saffron and ginseng. Neither is in this blend.
Step 4. Questions to ask any seller about a blend
- What is the exact amount of each ingredient per gummy?
- Is each extract standardized, and to which marker compound?
- Has an independent lab tested this batch, and can I see the certificate of analysis?
- Has the finished product been tested for undeclared drugs?
- Who is the manufacturer and where is the facility located?
The FTC's health products guidance says advertisers need competent and reliable scientific evidence for health claims, usually randomized controlled human trials, and that traditional use alone is not enough without a clear statement that no scientific evidence supports the claim. A seller who has this information would normally be glad to share it. We could not find it published.
Frequently asked questions
What are the ingredients in Stallion Power?
Muira puama, maca, catuaba, green tea extract, caffeine (5 mg), ashwagandha, L-arginine, Tribulus terrestris and horny goat weed, all inside one 82 mg proprietary blend, plus corn syrup, cane sugar, water, apple pectin, sorbitol liquid, natural flavors, citric acid and sodium citrate dihydrate.
How much of each ingredient is in one gummy?
The label does not say, except for caffeine at 5 mg. The other eight ingredients share the remaining 77 mg or less.
Does the blend have a proven effect?
We found no study of this exact blend. Studies of single ingredients are mixed, small, and generally use higher or different doses.
Is there a lot of sugar?
One gummy has 3 g of added sugar (6% of the daily value) and 10 calories. That is small per gummy, but it counts if you manage blood sugar.
Does it contain prescription drugs?
The label lists none. No one can confirm that from a label alone, which is why the FDA warns about this product category. See our safety guide for how to check.
