All cotton candy flavor. None of the pre workout powder fluff. We went to all 88 county fairs in Ohio and tried all the cotton candy to get just the right flavor. No one we talked to believed that it was for research. The perfect amount of sweetness spun into each serving: 150 milligrams of Caffeine for intense energy and focus 1 gram of Betaine to promote muscle gain and 1.6 grams of Beta Alanine for muscle building and endurance to go stronger for longer. It is simply the best pre workout for men and women you can get. The best workout is up to you.
