Nitric oxide is the primary molecule that transports oxygen and delivers nutrients to the skeletal muscle. This process is called hemodilation, which when enhanced with Bodybuilding Supplements such as AAKG or Nitro AKG is said to accelerate the process delivering even more oxygen and nutrients during workouts, resulting in stronger muscles and a more firmly toned physique.

Both AAKG and Nitro AKG are supplements which combine the amino acid arginine with alphaketoglutarate to create a drug free compound that increases this delivery.
Increases in delivery means more and better results form a workout, with noticeable increases in stamina, vitality and strength.

The most important point here, however, is that these increased results are acquired through a drug free medium making them safe and a popular choice among serious body builders and athletes alike.
