The Active Ingredient Is: Creatine Monohydrate

Creatine monohydrate is a natural compound that helps with quick energy production for muscles during short, high-intensity bursts.

This form is frequently used to boost athletic performance and comes in a premium, well absorbed form to assist muscle function during training (which athletes notice).

What Does Creatine Monohydrate Do?

Creatine monohydrate helps supply cellular energy by raising ATP availability, which supports strength gains and bigger training capacity in step with research from experts at big universities.

The pairing of creatine with protein and amino acids helps muscle protein synthesis and recovery processes that aid adaptive responses to resistance training, as described by experts at a leading university.
