ONYX NITRO boosts your body's nitric oxide to improve blood flow: more energy, more stamina and a better response, in and out of the bedroom.*
Nitric oxide relaxes the walls of your blood vessels and lets more blood through: that's the basis of a firm erection. L-arginine, L-citrulline and L-carnitine work together to help your body make more of it.*
Better circulation means more oxygen and nutrients for your muscles. Zinc supports natural testosterone production, and magnesium supports energy and rest.*
6 capsules a day: 3 in the morning and 3 at night. Many notice changes within a few days, and the result builds over 90 days.*
Every capsule holds what the label says, with the amount of each ingredient in plain view in the table. Spin it and open it.
