Hammer Nutrition Perpetuem Endurance Fuel $29.95
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.
What community has to say
Great Long Summit Attempt Nutrition
- Familiarity: I've put it through the wringer
I've used this on many PNW summit attempts, including Rainier, Baker, Adams and Hood, with great success. Matched with the Hammer Gel it totally rocks. You just gotta make sure to hydrate with this combination and those stomach cramps can be avoided.
I've used Hammer Nutrition products since their beginnings (e-Caps) and tried many others, but I continue to return to the one that has delivered when I really needed it.
This has some fat
- Familiarity: I've used it several times
I wanted to like this product. I'm sure it works great for others but for me it was major stomach cramps. I used it only for my very long rides and I suspect the fat content made my stomach turn. Flavor was not great either.
I got lucky
I bought this powder spontaneously, but this stuff performs really well. I always take this before my workouts geared towards anaerobic endurance. when I buy a second I will most definitely go with something other than strawberry-vanilla though. also the price isn't half bad
When the going gets tough, keep on goin'
I used this for the first time in the Whiskey 50 off road. I chose to use the multi hour bottle and this formula kept my muscles working hard for over 4 hours of explosive mountain bike racing. Do take caution, although this stuff works great for keeping muscle fatigue at bay it will not prevent cramping, I suggest using an additional electrolyte supplement if you know the weather is going to be hot. Bottom line is I will continue to use Perpetuem unless I find something better.
