Hammer Nutrition Perpetuem Endurance Fuel is the result of years of research and thousands of miles of testing in a variety of endurance disciplines. Perpetuem is Hammer's ultimate link to satisfying the body's fueling requirements no matter how long or difficult your exercise session or race is.

What's in Perpetuem?

Carbohydrates - As with all Hammer Nutrition fuels, no simple sugars are added to the carbohydrate profile. Perpetuem contains a specific maltodextrin, which provides nearly 87% of its caloric composition in long chain carbohydrates.

Protein - A new calcium-enhanced soy protein isolate known as "XT" makes up nearly 10% of the caloric profile of Perpetuem, the same percentage as is cannibalized 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 - Made from Energy Smart, the same healthy sweetener in Hammer Gel.

One container has 16 servings of Perpetuem. It's ideal for workouts and races over 3 hours. Perpetuem comes in three flavors -- Café Latte, Orange Vanilla, Strawberry Vanilla, and Unflavored.
