L-arginine is an essential amino acid that the body needs to function properly. Like other amino acids, L-arginine plays a role in building protein - which is why so many of our customers use this as a post-workout after their pumps in the gym!

If you are looking to bulk or tone up muscles, this supplement is important to use on a daily basis because the arginine protein is used to help build muscle and rebuild tissue. This process is extremely important for the growth of your muscles after a hard workout or pump sesh.

In addition to muscle growth, l-arginine helps to release nitric oxide in the blood. This NO booster acts to widen blood vessels in the blood stream, aiding in certain circulatory conditions. We've heard from several of our customers that this increase in circulation helps to enhance other areas of their life too - almost like a 2-in-one!
