For nearly a decade, NITRAFLEX® has been the name you trust when it comes to pre-workout formulas. And now, NITRAFLEX ups the ante by introducing Nitrosigine to the mix, and adding even more pure Citrulline to the formula. This 1-2 punch greatly increases pumps beyond expectations. The volume has been turned up on the energy, focus, and flavor as well. Lastly, there are no more artificial dyes in the formulas. All in all, this is the strongest and best-tasting NITRAFLEX yet!
Physiological Basis: “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.
