Horny Goat Weed Benefits: What the Evidence Shows
Horny goat weed benefits are not well proven. Memorial Sloan Kettering calls the evidence limited and mostly lab-based, and its main compound, icariin, may mildly inhibit PDE5 in the lab. Stallion Power lists horny goat weed extract last in an 82 mg blend, so one gummy holds 5 mg or less.

The evidence01
What are the proven horny goat weed benefits?
None are firmly proven. Memorial Sloan Kettering states that scientific evidence for epimedium, the plant's botanical name, is limited and that more studies are needed (MSKCC, Epimedium (horny goat weed)).
Its page covers bone and other uses rather than erection trials. The human trials that exist often used multi-herb formulas, which cannot show what one herb did (MSKCC, Epimedium (horny goat weed)).
A 2023 review of marketed ED supplements adds that most blends use negligible amounts of each ingredient (Petre 2023, ED supplements review).
Claims02
Which horny goat weed benefits does the Stallion Power label claim?
None by name. The label lists horny goat weed extract as the ninth and last line of the blend and makes no claim about it alone.
The front prints "Boost Performance†", "Support Confidence†" and "Maximum Strength†". Those cover the whole product, and the dagger points to the FDA statement that these claims are not evaluated.

| Directions | One gummy once daily, or as directed by a qualified health care professional | None in the page text |
| Medicine warning | Pregnant, nursing, taking medications or a medical condition: consult your doctor | No caution in the page text |

The math03
How much horny goat weed is in one gummy?
At most 5 mg. The label does not print the amount, but a blend lists parts from most to least by weight.
Caffeine is printed as 5 mg and sits fifth. Horny goat weed is ninth, so it cannot weigh more than that. This is our arithmetic from the label order, not a lab test.

Should horny goat weed influence your buying choice?
Not by itself. A plant with a long folk reputation is not the same as a plant with trial results.
Judge the whole label: the amounts, the evidence and the warnings. The horny goat weed page and the ingredient index show every line.
Next steps05
What should you check first?
Check your health and medicines before any supplement, and see a doctor about erection changes.
ED can signal heart or blood sugar problems. Keep taking prescribed medicine as directed. FDA has found hidden drugs in some male enhancement products (FDA, Tainted sexual enhancement products); we have not tested this gummy.

FAQ06
Horny goat weed questions
Is horny goat weed a natural Viagra?
No. Icariin may mildly inhibit PDE5 in lab work, but that is not the strength or proof of a prescription drug (MSKCC, Epimedium (horny goat weed)). Horny goat weed is sold as a supplement, not as an approved medicine.
What is the active compound in horny goat weed?
Icariin is the main compound studied. Memorial Sloan Kettering says it promotes estrogen biosynthesis in vitro and may mildly inhibit PDE5 (MSKCC, Epimedium (horny goat weed)). Those are lab findings, not results in men taking a gummy.
Where does horny goat weed sit on the Stallion Power label?
It is listed ninth and last in the 82 mg proprietary blend, as Horny Goat Weed Extract. Being last means it weighs no more than the 5 mg caffeine, by our arithmetic.
