Nitric Oxide Booster

Nitric oxide is a natural-occurring compound synthesized in the body from the amino acids L-arginine and L-citrulline and promotes vasodilation or increased blood flow which may lead to increased exercise performance and enhanced recovery. Natgrown’s L-arginine is ideal for strength and power athletes, or anyone looking to boost workouts to the next level.

Supports Muscle Growth and Recovery

Boosting your body’s nitric oxide during intense exercise may increase blood flow through your muscles, providing them with the oxygen and nutrients needed promoting performance, recovery, and growth.

Will order again

This product has increased my vascularity for really good pump feeling at the gym. It has increased the amount of blood flow and oxygen wich means greater improvements all around.

Seems to be helping circulation

Pretty much just started taking but seems to be helping circulation. I am hoping the availability will be better with this brand because the others I've taken aren't available every month. I'll update in a month or two.

No doubt!

I freaking love this product it does what it says, I've lifting weights for a while now, since using this product, I'm seeing my veins and my strength is coming back and I can tell the blood flow to my p**** is better, thanks..
