buffhunk29's comments are fully vaild. I find RPM's composition exceptional. The compounds in RPM's "Methyl AMP Complex" (Chocamine and Methyl Xanthine Anhydrous Caffeine) alone constitute a potent fat-burning arsenal, considering their individual nutrients. Some "full-fledged" fat-loss products do not even come close to matching "Methyl AMP Complex"s efficacy. Overall, RPM's competitive edge, in my opinion, is not just the combination of individually potent pharmaceutical grade compounds, but the impressive synergism they deliver. Superior product formulation at its finest!
