What It Actually Is
Horny Goat Weed, or Epimedium, is a plant genus used in traditional Chinese medicine, containing a compound called icariin.
What Research Generally Shows
Icariin has been studied in laboratory and animal research for its potential role in blood flow and libido, though robust human clinical trials are more limited than for some other ingredients on this list.
The Honest Gap
We don't have a confirmed dose for the Horny Goat Weed in IronPulseX's formula, or the icariin concentration of the extract used.
