### organic amino acid:

Creatine
* Most creatine is made from animal tissue
  - sold on the internet and even at health stores use what is refered as heavy creatine.
  * is already in the body as a natural substance. The body changes it to phosphocreatine. It is then stored as energy in the muscles. Creatine is mainly used in the lactate system and the phosphocreatine system because these two need more energy. They also take a part of the energy from the production or the absorption of creatine
* accepts a high energy phosphate from oxidative phosphorylation and becomes phosphocreatine.
* acts as a cellular volumizer when used in conjunction with exercise.
* actually helps the muscles retain more water molecules within the muscle cell.
* allows one to work out harder and recover faster
  - players to rapidly and safely gain muscle mass
* also buffers lactic acid production, thereby reducing muscle fatigue
  - the development of lactic acid allowing for a more enduring workout
