Okay so it WILL not affect my growth ?
and what if i start taking protein shake and creatine ?
IT WILL! don't listen to him. My mate (he's 19 right now)
Stopped growing because he started lifting at young age (around 14 years old). And wth? At the gym they warn us young agers not to lift because it affects our growing process. Dont do it, just do the simple fitness things, but don't lift. I see many of those 'cool' big muscle guys at my school; they all stopepd growing, I past them all
-EDIT-
Don't over-do it.
