Nitric oxide levels once had a pre-set limit - until NO2 Black. Nitric oxide generators provide your body with arginine - the building block of nitric oxide. But it's the nitric oxide synthase (NOS) enzymes inside your body that convert the arginine into nitric oxide. Nitric oxide synthase is the rate limiting factor in nitric oxide production.

NO2 Black provides a potent dose of arginine (AKG) delivered with its clinically tested extended release delivery technology, pHylex9. The 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).

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.*

NO2 Black is ideal to stack with CE2.
