Product Description Muscle Nitro can give you up to 11% more exercise capacity. It can improve aerobic capacity by an astonishing 300%. And that's not based on some pie-in-the-sky claim, but on results derived from a University study conducted by world-famous Exercise Physiologist, Dr. Thomas Fahey.This happens because the succinates in Muscle Nitro make your muscle cells more efficient at getting the oxygen in your blood into their energy-production cycle. This literally means more "wind". Think about being 11% better tomorrow than you were in your last race.
