L-Arginine SX-7 Black Onyx

Advanced, Triple-sourced L-Arginne

L-arginine SX-7 Black Onyx delivers a powerful, pump-inducing matrix that quickly disperses into your bloodstream when you need it most!*

Nitric Oxide (NO) is a signaling molecule that increases blood flow to the muscle and is absolutely crucial in the formation of muscle pumps! The amount of NO your body makes is tightly controlled by an enzyme called nitric oxide synthase. When you train hard, the activity of nitric oxide synthase increases, which means NO is made. When you start exercising, signals are sent to the nitric oxide synthase enzymes to make a lot ore NO. This allows NO to work quickly on the muscles and the blood vessels to create a pump and influence muscle expansion. Nitric Oxide helps to relax blood vessels and cause rapid vasodilation, massive pumps, the most extreme muscle hardness and the freakiest vasculariy with every rep!*

The advanced arginine matrix in L-Arginine SX-7 Black Onyx 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!*
