The Best Endurance Supplements of 2023

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. A boost in protein synthesis can help to improve lean muscle mass, endurance and performance. Be a man & take l arginine supplements!

For the ultimate male physique and performance, you can dominate your life by adding havasu's l arginine supplement to your daily routine. By increasing l-arginine, you start to add more nitric oxide in your bloodstream, which directly affects blood flow.

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 - especially in the bedroom.

It has been proven that adding Beet Root with L-Arginine and L-Citruline, you can increase the levels of nitric oxide even more. Because of that, customers know that havasu's arginine supplement is the most potent for performance, endurance and vascular growth.

In addition to performance and endurance, the nitric oxide boost (NO) is important for p function because it helps blood vessels relax, so more oxygen-rich blood can circulate through your arteries. Healthy blood flow to the arteries of the area below is essential for normal function - and your significant other won't be disappointed!
