Manufacturer Says:

950% More Nitric Oxide - All Day Long

NO2 Black is the first patented extended-release nitric oxide generator designed to deliver upper limit nitric oxide - all day long. It is enhanced by the patent-pending ACTINOS(2)- technology. ACTINOS(2)- was developed to increase NOS (nitric oxide synthase), the rate-limiting factor in the human body’s ability to generate nitric oxide.

With more NOS, NO2 Black delivers upper limit nitric oxide for massive gains in lean mass, “in-gym” muscle recovery, and skin ripping pumps. NO2 Black is also enhanced with alpha lipoic acid to help you keep your muscle gains.
