L-Arginine SX-7 Black Onyx

Product Description


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 more NO is made. When you start exercising, signals are sent to the nitric oxide synthase enzymes to make a lot more 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 vascularity with every rep!

  • Powerful nitric oxide precursor
  • Supports vasodilation & nutrient delivery
  • Advanced, triple-sourced L-arginine
