Nitric oxide. The “perpetual pump.” Cell-signaling vasodilators. You’ve heard about it, now it’s time to add it to your training program. What is vasodilation? In plain English, it’s when blood vessels dilate or relax. When blood vessels relax, they widen. Nitric oxide (NO) is the key here. NO is an important endogenous pulmonary vasodilator. As a vasodilator, nitric oxide has the ability to increase your body’s ability to deliver blood to working muscles. More blood means more oxygen and nutrients that are being pumped into skeletal muscles. All this translates into bigger, fuller pumps and better overall gains. In fact, with NO, you can expect increased muscle size, strength, endurance, and quicker recovery times. NOX3 is like other vasodilators including NO2 by MRI and NOX2 by Pinnacle. However, NOX3 is better because it contains a powerful third ingredient, ornithine alpha-ketoglutarate. Unlike both NO2 and NOX2, NOX3 functions as a powerful vasodilator; as an anti-catabolic supplement which helps preserve muscle mass; and, as part of the arginine-ornithine combo, can boost growth hormone levels. In other words, unlike NO2 and NOX2, our NOX3 also helps preserve muscle after training and boosts GH levels. There are numerous studies that support both the anticatabolic effects of ornithine AKG and the growth hormone boosting effects of ornithine combined with arginine. It's because of the unique ingredient, ornithine alpha-ketoglutarate. In short, NOX3 is more well-rounded, more effective overall for the athlete, and more economically-priced. The difference is in the third ingredient, which is why it is called NOX \3\.
