HumaPro® is formulated with all of the essential amino acids in the exact ratio and sequenced delivery for what the human body requires to fully utilize them. Furthermore, the unique delivery system of HumaPro® is designed to have all of the essential Amino Acids arrive at the muscle tissue, at the same time. While other proteins are only in the incorrect ratios, but they also arrive at different times. This is something to think about when you see other products on the market that may seem to copy HumaPro®. Years of science has been put into the unique delivery system behind HumaPro® and the exact amino sequence.
