My brother goes to this guy that he pays $60 a month for bodybuilding information. The GUY IS ABSOLUTLY HUGE! the biggest dude i've seen in real life, this is the only reason i believe him. Anyway he says prohormones do ireversable damage to the bodies natural hormones. Have you guys heard anything about this? Or is he full of shit?

I wanted to know because i wanted to try 1-ad or 1-test soon.
