Man, I think I hear this question everyday. No, as JP said lifting will not stunt your growth. Watch your p enis though. There was a recent study conducted on rats that performed a total body routine based on compound movements a while back. After the rats performed the last set of squats their p enis size started to shrink dramatically. This is also the justification for isolating muscle groups from every angle with isolation exersizes, being that the isolation exersizes do not shink the male p enis as the compounds do.
