What the name covers
Horny Goat Weed is a common name used for Epimedium species. Marketing often focuses on icariin, but not every product clearly states a standardized icariin percentage.
VigorPeak label context
The seller lists 8 mg of a 10:1 Horny Goat Weed extract and describes it as equivalent to about 80 mg dried herb. The direct page does not state a standardized icariin percentage in the material we reviewed.
Why that matters
Two Epimedium extracts with the same herb name can differ in species, extraction and active-compound concentration. A dried-herb equivalence does not automatically answer those questions.
Use evidence language carefully
Traditional use and mechanistic research can justify studying an ingredient. They are not a guarantee of a particular erection, libido or circulation outcome from a finished supplement.
