Product Description:Made in Wisconsin, our Whey Protein Isolate is made using a cold, micro-filtered process. This powder is a very rich source of protein, which accounts for 90% of its total weight. It builds and repairs muscle tissue and aids in the recovery of exhausted muscles after high intensity physical exercise. This protein powder contains branched-chain amino acids (BCAAs), essential amino acids that are largely found in muscle tissues and used primarily in the production of proteins and in enhancing physical performance. Add your own sweetener if desired.
