NOxious is a leading Nitric Oxide booster and pump product utilizing huge doses of Citrulline, Glycerol, Agmatine, Norvaline and Epimedium to drive Nitric Oxide through the roof and deliver insane vascularity with killer pumps! Both Citrulline and Agmatine work synergisticly to increase the production of Nitric Oxide while Glycerol increases blood volume and dramatic muscular fullness. L-Norvaline was actually added for its actions as an arginase inhibitor, an enzyme normally responsible for breaking down Nitrix Oxide, which means by using L-Norvaline pumps are far stronger and last significantly longer. Last but not least, Epimedium for Icarrin is actually a PDE Inhibitor, which is the same pathway that viagra works through. This offers an innovative and effective way to enhance nitric oxide production and add a different aspect to this amazing profile. Get Pumped, Get Huge, Get Noxious!
