Yo, beat his ass if he even brings it up again, bro! I mean, 16 is just ridiculously young to start using AAS. Unless he's not even going through puberty yet or something. In which case he should see an informed doctor, so that it can be done right. Maybe 20mg of var would help for stunted growth. But again, I don't know if this is your bro's problem or not. Probably not. Most likely he just doesn't know how to eat right. Show him the diet section of this forum.
