In active men aged 18–40 undergoing resistance training, daily supplementation with 3 g of micronized creatine monohydrate (KleanCREATINE™) for eight weeks results in a 60% increase in chest press one-repetition maximum strength, which is significantly greater than the 49% increase observed with a standard marketed creatine monohydrate formulation.

Finely ground creatine enters the bloodstream faster and more completely, so more of it gets into muscle cells. Inside the muscle, it turns into a high-energy molecule that quickly restores the fuel used during heavy lifting. This lets the muscle work harder and longer without getting as tired, and also causes the muscle cells to swell with water, which signals them to grow bigger. Together, these effects allow for stronger lifts and more muscle mass over time.
