Creatine

is basically a fuel source for ATP, which is an energy system used for short intensive use of muscle power. Supplementing with creatine can also help delay fatigue, meaning you can train harder and longer.

Creatine monohydrate is the king of nutritional supplements: it is unbeatable for its ability to help the body's muscles perform at their best and grow fully. Micronized creatine monohydrate has smaller particles and is designed to be absorbed quickly, so it can kick in when you need it most.
