I've been working out on and off for about 2 years now. I recently just finished M5 by cellucor and i wasn't that happy and plus it cost way to much so i bought tribulus fuel by twinlab, creatine fuel by twinlab(only b/c it was $10)and gnc ZMA. Thanks for the info i was just wondering if people got good results from it. Oh yeah i also take 100% whey protein. Is what i'm taken a waste or what?
