Gold Standard 100% Casein to be broken down into its amino acid
subcomponents. By using only premium micellar casein as a protein
source, ON has created a formula that sets the standard for slow
digesting protein support. In addition to 24 grams of protein, Gold Standard's also contains 5 grams of BCAAs per serving and glutamine and glutamic acid as well.
