Creatine is one of the first supplements any athlete adds to their training stack - in the gym, on the field, or on the platform. It’s a tried and true staple in sports nutrition for it’s ability to pack on serious size. 
 
Here’s the rundown: Adenosine 5'-triphosphate (ATP) is the main molecule for storing and transferring energy in muscle cells. ATP is broken down to produce energy. You can only perform at maximum intensity as fast as ATP is replenished - and the body uses ATP faster than you can build it back up.

Creatine increases your muscles’ phosphocreatine stores, which helps with the formation of new ATP, allowing you to produce more energy and fuel your muscles during high-intensity exercise
