I love Icariin. Horny Goat Weed here in the states usually has only 10 mg per pill of the active ingredient...that's why I take 6 times the recommend amount once before work outs and every night before bed.

You can find it in 60 mg which is the most I think you can buy; but you need to buy it online.

I've used it in the past, but not combined with my amino stack, and it worked okay.
