Pro Performance Weight Gainer contains 50 grams of high-quality protein in a wellness formula designed to digest and release varied intervals throughout the day to ensure your muscles get the amino acids they need. This formula is designed to support your body composition goals with naturally occurring branched-chain amino acids (BCAA), which may help reduce muscle breakdown during exercise, added medium-chain triglycerides (MCT), which are quickly absorbed by the body for use of energy, and a dual carbohydrate system to preserve and replenish energy stores. Pro Performance Weight Gainer also includes naturally occurring arginine to fuel muscle cells and influence the cardiovascular system through nitric oxide production.
