Stay strong and steady from start to finish with Perpetuem, Hammer’s groundbreaking long-duration fuel. For exercise sessions lasting beyond three hours, carbohydrates alone are insufficient.

Perpetuem steps it up with the addition of healthy fatty acids and protein. While those fats provide satiety and encourage utilization of the body fat stores, the easily-digested protein curbs lean muscle cannibalization and stabilizes energy levels.

The addition of lactic acid buffering amino acids and free radical neutralizing antioxidants further prevent fatigue and support high output over the long haul. Tested and proven in the world’s toughest events, Perpetuem goes the distance.

Caffé Latte flavor contains 25 mg of caffeine per serving.


  • Ultra-endurance fuel.
  • Stabilizes energy & blood-sugar.
  • Maximizes fat utilization.
  • Protects lean muscle mass.

Great for maintaining strength on 3 hour rides!

I use Perpeteum on rides of over 3 hours - up to 7 hours in length.

It keeps fueling energy for those longer rides especially when used in conjunction with HEED.

I should mention that I also need some protein after 4 hours too like a PB&J sandwich to keep from feeling carbed-out. Perpeteum also greatly aids in recovery from longer rides.

Why doesn't this product contain electrolytes?

I don't understand why this product doesn't contain electrolytes. It's specific designed for endurance, so why leave that out? When using this on long rides (as intended), I've cramped up at the worst times. I carry enough items in my back pockets to then also have to carry tablets or anything else. I've resorted to adding electrolyte tablets into the mix, which is very messy and sticky. Not ideal
