It is converted into creatine phosphate or phosphocreatine and stored in the muscles, where it is used for energy.
Creatine enhances the body’s capacity to perform high-intensity work (and assists greater muscle size and performance gains as a result).
Creatine (creatines high energy molecule form, stored within cells) is used to supply the type 2B muscle fibers (the ones that get largest in size) with immediate energy, ensuring these muscles do not prematurely fatigue.
