This might sound weird but I makes me feel kinda "estrogen-y" emotionally. Physically the effects are negligible but it might just be the brand. I'll try a 40% extract after this bottle is done and if I don't see great results I'll drop it in favour of something else. I'm planning on running a bottle of androhardv3 in the next couple of weeks though so itll probably be a few months before I get around to trying a different bottle of icariin.
