- How It Works. L-arginine, AAKG, citrulline malate, and beet root work to funnel clean oxygen and nutrient-rich blood straight into your muscle cells. This pre-workout fuel kickstarts the anabolic process, and means greater endurance and stronger pumps.
- Heart Healthy. During exercise, nitric oxide is released into the blood vessels, causing them to expand and improve blood flow throughout the body. N.O. Pro accelerates the production of nitric oxide and increases blood flow, supporting a healthy heart.
