  • Clinically Studied CFB & Vasoactive Compounds
  • Highest Concentration 1-Scoop Potency
  • Raw Muscle Building Power*

This new breed of concentrate is an annihilating force to reckon with. Regenerating new muscle at an anabolically-expedited rate with intensity beyond belief is what Nitraflex is all about. To make you the predatory beast whether on stage, at the gym, or when strength needs to be summoned up full-tilt.

How does "seething intensity" look and feel? Start taking Nitraflex today to find out. The size you get from tearing down flesh from within will be living proof.

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.*

Nitraflex Properties

1-Scoop Potency

Nitraflex is so potent, only one serving is necessary. Do not exceed one scoop in a single 24-hour period.


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.*


Effective Doses of Beta-Alanine

The clinically-proven performance enhancer beta-alanine was not "fairy dusted" in this formula. Rather, we added an exceptionally powerful dose that you will feel working following your very first serving.


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. (When you see yourself getting bloated, you may be fooled into thinking the product is "working.") We left it out of Nitraflex precisely for this reason. Thus making Nitraflex ideal for pre-contest prep.*


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.*
