A single scoop of Whey + Muscle Builder contains 30g of whey protein. Whey protein begins its life as milk, and after an advanced manufacturing process, becomes one of the highest quality sources of protein and an ideal choice for men and women. Not only does whey protein provide serious athletes with essential and branched-chain amino acids, but it also helps to repair and rebuild muscle. Whey is also a “complete” protein, meaning it contains all the essential amino acids that the human body requires for optimal performance, muscle repair, and growth and is also high in key branched-chain amino acids (BCAAs), which activates a certain pathway in the body that stimulates muscle protein synthesis, which is how your body makes muscle. Our whey protein has been filtered using Multi-Phase Filtration Technology for less fat, lactose, and impurities than cheaper protein sources.
