To create GOLD STANDARD ISOLATE we start by selecting only the highest quality whey protein which undergoes a series of sophisticated filtration processes to âisolateâ out excess fat cholesterol and sugar. A portion of this Whey Protein Isolate is then hydrolyzed â broken down into smaller chains of amino acids. The final product is a fast-digesting complete protein containing no more than 1 gram of carbohydrates less than a gram of fat and more than 80% pure protein per serving to support your muscle building performance and fitness goals.
