The Bigger Picture of WheyWhey Protein isolates is 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 serving, and a lot less f 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, Ultra filtered Whey Protein Concentrate , Hydro whey Hydrolyzed Whey PeptidesTypical Amino Typical Amino Acid Profile (milligrams per serving) Essential Amino Acids, Tryptophan 405, Valine 1422, Threonine 1654, Isoleucine 1573, Leucine 2233, Lysine 2233, Phenylanine 748, Methionine 492, Conditionally Essential amino Acids, Arginine 505, Cystine 494, Tyrosine 703, Histidine 423, Proline 1509, Glutamine & Precursors 4082, Nonessential Amino Acids, Aspartic Acid 2508, Serine 1126, Glycine 412, Alanine 1180.Beyond The BasicsPacked with Whey Protein Isolates (WPI), Higher Protein Percentage (24 grams of protein 75% protein by weight).
