NOS Matrix is the newest technology in promoting muscle growth, increasing strength, speeding muscle recovery and sustaining long lasting muscular blood flow. NOS Matrix utilizes a compound compound called arginine alpha-ketoglutarate (AKG) to boost Nitric Oxide levels in skeletal muscle. Nitric oxide is the muscle's "cell-signaling" molecule responsible for blood flow (hemodilation), oxygen delivery, glucose uptake, muscle velocity, power output, and muscle growth. Besides having a high quality, pharmaceutical grade L-Arginine-alpha-Ketoglutarate, the system behind NOS Matrix is dependent on the pHCD System (pH-controlled, sustained-release delivery matrix). The pH-sustained release mechanism that our chemists have developed is the only way to administer AKG into the human circulatory system by means of a patented extended release mechanism.
