With icariin the only study i know of that states it works on acetylcholinesterase is in the CNS with neuroprotective properties in senescence-accelerated mouse prone 8 mice. Im not sure how you can apply that data to sports performance.Phytoandrogen effect. Action is similar to DHT. By the way Icariin also lowers the effect of acetylcholinesterase.
And the phytoandrogen effect...elaborate please?
