Double Rich ChocolateWhy Protein Isolates; Primary Source: 24g Protein, 5.5g BCAAs, 4g Glutamine & Precursors; 31 Servings. The bigger picture of whey: Why Protein Isolates are 90% pure protein by weight. They are the purest and most expensive form of why protein that exists. That's why they are the first ingredients you read on the 100% Whey Gold Standard label. By using Why Protein Isolates as our primary protein source, we're able to pack 24 grams of the purest, muscle building protein per serving, and a lot less of the fat, cholesterol, lactose and other stuff that you can do without. There's no question this is the standard by which other whey proteins are measured. The advanced gold standard why protein blend: 100% Why Gold Standard is made of an exclusive blend of-Microfiltered Whey Protein Isolates; Ion-Exchanged Whey Protein Isolates; Ultrafiltered Whey Protein Concentrate; HydroWhey Hydrolyzed Whey Peptides. Typical amino acid profile (milligrams per serving): Essential Amino Acids (EAA's)-Tryptophan (405), Valine (1422), Threonine (1654), Isoleucine (1573), Leucine (2531), Lysine (2233), Phenylalanine (748), Methionine (492); Conditionally Essential Amino Acids (CAA's)-Arginine (505), Cystine (494), Tyrosine (703), Histidine (423), Proline (1509), Glutamine & Precursors (4082); Nonessential Amino Acids (NAA's)-Aspartic Acid (2508), Serine (1126), Glycine (412), Alanine (1180).
