Whey Protein Isolates are the purest form of whey protein that exists. Hydrowhey consists of proteins strategically broken down (hydrolyzed) into smaller pieces called peptides for faster utilization by the body. Both are costly to use, but whey protein isolates and Hydrowhey hydrolyzed whey peptides are the best whey proteins that money can buy. Thats why theyre the first few ingredients you read on the Gold Standard 100% Whey label. By using whey protein isolates and Hydrowhey as primary ingredients, were able to pack 24 grams of the fastest, muscle-building protein into every serving with a lot less of the fat, cholesterol, lactose, and other stuff you can do without. There’s no doubt that this is the standard by which all other whey proteins are measured.Ingredients Protein blend (whey protein isolate, whey protein concentrate, whey peptides), cocoa (processed with alkali), lecithin, natural and artificial flavors, acesulfame potassium, aminogen, sucralose, lactase.Free Form Contains milk and soy (lecithin) ingredients.
