The true strength of whey. 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. That\'s why they\'re the first few ingredients you read on the Gold Standard 100% Whey label. By using whey protein isolates and Hydrowhey as primary ingredients, we\'re 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. The Advanced Gold Standard Whey Protein Blend: Gold Standard 100% Whey is made of an exclusive blend of: microfiltered whey protein isolates; ion-exchange whey protein isolates; ultrafiltered whey protein concentrate; Hydrowhey hydrolyzed whey peptides. Beyond the basics: packed with whey protein isolates (WPI); higher protein percentage (24 grams of protein; nearly 79% protein by weight); includes Hydrowhey, strategically hydrolyzed, low molecular weight whey peptides to make protein faster acting
