NOW WITH NITROSIGINE FOR EVEN GREATER PUMPS! 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’s no more artificial dyes in the formulas. All in all, this is the strongest and best-tasting NITRAFLEX yet!
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 benefits 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.
1-SCOOP SERVING: NITRAFLEX is so potent, only 1 scoop (1 serving) is necessary. Do not exceed 1 scoop in a single 24-hour period. Do not take NITRAFLEX within 5 hours of bedtime.
200mg OF BORON CITRATE IN EVERY DOSE OF NITRAFLEX: This trace mineral has been shown to lower estrogen, while raising free testosterone by 28.3% in as little as 7 days!
