Advanced, Triple-Sourced L-Arginine

L-Arginine SX-7 Black Onyx delivers a powerful pump-including matrix that quickly disperses into your bloodstream when you need it most! This advanced arginine matrix supplies three forms of L-arginine, the critical precursor to nitric oxide. Plus, it's sugar free and non-stimulant so it can be stacked with any other SX-7 Black Onyx product for your best workouts.

Powerful Nitric Oxide Precursor

MuscleTech researchers developed the most advanced, ultra-pure, triple-sourced L-arginine formula ever. L-Arginine SX-7 Black Onyx delivers 6,000 mg of L-arginine, including ultra-pure micronized L-arginine, for rapid uptake and dispersal in your body. Flooding your body with this powerful nitric oxide precursor primes you for extreme pumps, enhanced blood flow and nutrient delivery.

Scientifically Superior Formula

When you train, your body releases calcium in the endothelial cells that line your blood vessels. This causes the enzyme nitric oxide synthase to create nitric oxide from available L-arginine. As the nitric oxide leaves the endothelial cells, the blood vessels relax, causing vasodilation. By supplying a massive dose of L-arginine to your body, L-Arginine SX-7 Black Onyx helps trigger extreme nitric oxide production for superior vasodilation effects and massive muscle pumps.
