MRI NO2 Black Full Cycle drives nitric oxide optimization on four powerful fronts; feeding, fueling, protecting and generating muscle.

Here is how it works:

First, the L-arginine precursor, L-citrulline, effectively "feeds" more L-arginine into the nitric oxide production matrix. Second, premium sources of L- arginine provide the "high-octane" base that fuels nitric oxide conversion. Third, L-norvaline helps combat the arginine converting enzymes to help support greater reserves of nitric oxide fuel. Fourth, the nitric oxide generating nitric oxide systems "factories" are up-regulated on two fronts, yielding up to 1250% more nitric oxide.*
