Gold Standard Isolate

All of the protein in each serving of Optimum Nutrition Isolate is from Whey Isolate, ultra-filtered for exceptional purity. By using only high-quality Whey Isolate, we're able to pack 25 grams of protein into every serving with just 1 gram of sugar and 1 gram of fat. Mix a scoop into cold water or milk first thing in the morning, before endurance training or after weight training to kick-start recovery. That way, you can get back to chasing ambitious goals tomorrow.
