Justin:

NO2 is a product containing the amino acid arginine. Arginine is a
precursor to nitric oxide, which causes a vasodilation response in the body
(blood vessels open up). There is no evidence that this product will do
anything to enhance strength or muscle mass gains.

Many of my friends use a supplement called "NO2".
I believe that this product is based on Nitrogen supplementation,
but I'm not sure exactly what the product is...
