Well I've been working out and I just finished the eight week program. lost some weight I'm starting to see some muscle growing but I'm also over weight. I'm 18 I'm 5'8 and I weigh about 205lb, I wanna start using the AMP from GNC for that extra help to gain more muscle and gain more stamina when I work out but I just wanna know if It'll work for me and well it make me gain or lose weight? Because I don't wanna gain more weight.
