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

High Citrulline: Arginine RatioArginine 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-AlanineThe 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 FreeCreatine 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.*
