Never before has such a complete and effective endurance drink been available to athletes. Perpetuem is a result of several years of research and thousands of miles of testing in a variety of endurance disciplines. Since its introduction in 2003, Perpetuem has allowed athletes to conquer the most extreme workouts and races with complete confidence! Perpetuem represents the ultimate, never-before-available link to satisfying the body's fueling requirements no matter how long or difficult your exercise session or race. - Carbohydrates - As with all Hammer Nutrition fuels, we never add simple sugars to the carbohydrate profile. Perpetuem contains a specific maltodextrin, which provides nearly 87% of its caloric composition in long chain carbohydrates. - Protein - A calcium-enhanced soy protein isolate known as "XT" makes up nearly 10% of the caloric profile of Perpetuem, the same percentage that is cannibalized from muscle tissue during long, slow endurance workouts. This particular soy protein contains a very high amount of intact, cardiovascular-enhancing isoflavones. - Fat - A de-oiled "super lecithin" (extracted from the soybean) is ideal for consistently and reliably fueling the body and maximizing energy production from stored fatty acids. - Sweetener - Perpetuem contains Energy Smart®, the same healthy sweetener in Hammer Gel.
