The Active Ingredient Is: Creatine Monohydrate

Creatine monohydrate is a popular supplement that helps energy generation in muscles during quick, intense workouts. This form offers a highly absorbable source of creatine to help fast energy delivery in exercise‑related muscle performance.

What Exactly Does Creatine Monohydrate Do?

Creatine monohydrate helps to generate energy quickly for explosive bursts and joins in muscle energy metabolism during tough training. It helps to keep performance in high‑intensity workouts and supports normal energy production processes within the body. This product isn't meant to diagnose, treat, cure, or prevent any disease.
