PRO BCAA by Max Muscle, is a scientifically-based formula to provide the body with high potency branched-chain amino acids (BCAA) in the ideal 2:1:1 ratio of leucine, isoleucine, and valine. As a versatile formula, Pro BCAA is specifically designed to benefit both pre-, during, and post-workouts. For the pre- and during workout, this comprehensive formula is designed to support the energy fuels needed for high intensity and endurance workouts. For the post-workout, it functions to support rapid recovery, muscle anabolism and anti-catabolic effects. The BCAAs (leucine, valine and isoleucine) are known to be highly concentrated in muscles (35%) and have been shown to serve as important fuel sources for skeletal muscles during periods of high-intensity exercise.
