NO2 Black represents a quantum leapin nitric oxide science. First, NO2 Black sets the standard by giving you the purest Arginine-AKG (ArginPure) Delivered with its extended-release delivery technology, pHylex9. Second, NO2 Black's revolutionary NOS-Enhancing peptide fraction up-regulates nitric oxide synthase (NOS) and increases your nitric oxide levels as much as 950% over baseline arginine derived nitric oxide (ADNO). Third, the NO2 Black formula includes alpha-lipoic acid, designed to boost your insulin sensitivity and nutrient uptake. Simply put, NO2 Black is the most potent nitric oxide generator ever conceived.
