Drive/RPM is one of the most potent stacks available. There are several non-sponsored logs available describing the dramatic gains users derived from the stack. You might need to do some fine-tuning of the doses until you hit the protocol that works best for you. Expect impressive increases in strength, endurance, hard lean mass, fat loss, and anti-catabolism, to name a few. Once you are done with your first RPM/Drive stack, you would be looking forward to your second :thumbsup:
