Bought the 6lb. fruit drink because the regular creatine pills i was taking didn't give me any noticeable gains after a month. After 3 weeks taking cell tech as recommended i feel everything is amped up. Not a big science guy, or guru on these things, but the carb load thing must be for real. I take the nitro tech also, and the multi vitamins. Great stack, and i'm sold on MuscleTech products.
