Seems to me more and more people consider taking aromatase inhibitors or estrogen suppressants as a sort of supplement.
Well, they are not steroids, so what do you say, natural or not?
They aren't steroids, but they are definitly not as worthless as tribulus, avena sativa or fenuplast.
edit> i am thinking of 'supps' like novedex, rebound xt and the likes as well as arimidex, letrozol, whatever...
