To create GOLD STANDARD 100% ISOLATE, They start by selecting only the best quality whey protein, which undergoes a series of sophisticated filtration processes to isolate out excess fat, cholesterol and sugar. A portion of this Whey Protein Isolate is then hydrolysed broken down into smaller chains of amino acids for easier digestion. The final product is a fast-digesting complete protein containing no more than 1 gram of carbohydrates, less than 1 gram of fat and more than 80% pure protein per serving. Optimum Nutrition put in the hard work to assure super quality, so you can focus on achieving ambitious performance goals.
