The Bigger Picture of Whey. Whey Protein Isolates are 90% pure protein by weight. They are the purest and most expensive form of whey protein that exists. That's why they are the first ingredients you read on the 100% Whey Gold Standard label. By using Whey 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 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 whey protein blend: 100% Whey Gold Standard is made of an exclusive blend of: Microfiltered Whey Protein Isolates; Ion-Exchange Whey Protein Isolates; Ultrafiltered Whey Protein Concentrate; HYDROWHEY Hydrolyzed Whey Peptides. Typical Amino Acid Profile (milligrams per serving) Essential Amino Acids (EAAs) Tryptophan 405, Valine 1422, Threonine 1654, Isoleucine 1573, Leucine 2531, Lysine 2233, Phenylalanine 748, Methionine 492; Conditionally Essential Amino Acids (CAAs): Arginine 505, Cystine 494, Tyrosine 703, Histidine 423, Proline 1509, Glutamine & Precursors 4082; Nonessential Amino Acids (NAAs): Aspartic Acid 2508; Serine 1126; Glycine 412, Alanine 1180. Beyond the Basics: Packed with whey Protein Isolates (WPI). Higher Protein Percentage (24 grams of protein; 79% protein by weight). Includes Hydrowhey, strategically hydrolyzed, low molecular weight whey peptides to make protein faster acting. Contains lactase and aminogen digestive enzymes to enhance utilization. Whey protein microfractions including Alpha-lactalbumin, Glycomacropeptides, Beta-lactoglobulin, Immunoglobulin G (lgG). Lactoferrin, Lactoperoxidase, and various growth factors. Over 4 grams of Glutamine and glutamine precursors. More than 5 grams of BCAAs (Leucine, Isoleucine, and Valine) in each scoop.
