”Reactive hyperemia” describes the increase in muscle blood flow that occurs during high-intensity resistance exercise and produces the “pump” associated with increases in muscle size. The NITRAFLEX® pre-training formula contains ingredients that in animal, in vitro and clinical studies suggest possess properties that may help advanced athletes maximize energy, intensity, vascularity and reactive hyperemia (pumps) during their workouts, and provide long-term support of testosterone and Nitric Oxide levels in the healthy range when used as directed.‡
UNIQUE PROPERTIES OF SOME OF THE KEY COMPOUNDS IN NITRAFLEX®+C: POWERED BY NITROSIGINE®:
This new formula boasts Nitrosigine® as its only source of Arginine. Nitrosigine® has been shown to inhibit the enzyme responsible for breaking down Arginine, making it the superior choice of arginine supplementation and a perfect synergistic partner to L-Citrulline.‡ Nitrosigine® has scientifically validated that bene‑ts last up to 6 hours after dosing. In addition to vasodilation (pump) and overall performance-enhancing benefits, Nitrosigine® is clinically shown to increase mental focus, making it a truly well-rounded and multi-faceted addition to any effective pre-workout formula.‡

Still my favorite pre for years now. I’m 42 and weight train 6 days a week. Started in my 20’s. I have tried a ton of pre over the years. Keep coming back to nitroflex. It’s strong and it works. I alternate between the creatine version and the non creatine.
