Clinically Tested in a Double-Blind Study!† Boost Bench Press Strength Up to 10 lbs in Just 2 Wks!† Creatine Free Hyperemia & Testosterone Enhancing Powder Highly Concentrated More Than 3X Strength Clinically-Studied CFB + Vasoactive Compounds† 30 Servings Dietary Supplement Naturally and Artificially Flavored Vasodilation Testosterone Reactive Hyperemia (Muscle Pumps) Strength Energy Hardness CarnoSyn - Carnosine SynthesizerNutraceutical Facts: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 vitro, animal 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: 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. High Citrulline:Arginine Ratio: Arginine is a proven precursor to nitric oxide (NO), a vasodilator. What most people don't know is that arginine supplementation stimulates the activity of arginase, an enzyme that breaks down arginine. Over time, this may actually result in reduced arginine and NO levels, in turn causing your pre-workout formula to stop working. Research suggests that supplementing with a high ratio of citrulline to arginine may reduce this risk by avoiding overstimulation of arginase.† CFB Helps Support Testosterone: In a clinical study, calcium fructopyranose borate (CFB) was shown to increase total and free testosterone within 3 hours of a single dose equivalent to just over 2 scoops of Nitraflex.† A longer-term study reported an increase in free testosterone by up to 29%.† Effective Dose of Beta-Alanine: The clinically-proven performance enhancer beta-alanine was not "fairy dusted" in this formula. Rather, we added a powerful dose that you will feel working following your very first serving. (May promote slight, tingly-cerebral sensation). Creatine-Free: Creatine causes water retention, which can make achieving a dry, hard muscular look even more difficult. Sometimes creatine is added to products precisely for this reason. We left it out of Nitraflex precisely for this reason. Thus making Nitraflex ideal for pre-contest prep and lean muscle physique.† 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.
