Now with NITROSIGINE® for even greater pumps!
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's no more artificial dyes in the formulas. All in all, this is the strongest and best-tasting NITRAFLEX® yet!
Unique Properties of Some of the Key Compounds in NITRAFLEX®:
- 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-faced 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.
- 200 mg 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!
- Cognitive Enhancers: NITRAFLEX® contains unique ratios of scientifically validated compounds that help you remain alert, intense and focused while you're flying from set to set with veins fully dilated and muscles pumped to the extreme.
Begin by assessing your tolerance with half a serving of NITRAFLEX® mixed with 5 oz of cold water. Consume within 30 minutes before working out. Depending on tolerance, mix 1 serving (1 scoop) of NITRAFLEX® with 8-10 oz of cold water and consume within 30 minutes before working out. Do not take within 5 hours of bedtime.
