Horny Goat Weed Extract comes from the Epimedium plant and is famous for icariin, which is what makes it work. In the same way that some drugs are used to treat erectile dysfunction, this natural substance blocks phosphodiesterase. Horny Goat Weed helps men get and keep strong erections by relaxing smooth muscle tissue and bringing more blood to the groin area. It also has benefits similar to testosterone, which could boost libido and sexual desire. Its ability to lower cortisol levels and fight stress makes it even more useful, and it is a main ingredient in Alpha Bites.
