Product Overview

These research studies claim that L-Arginine supplementation may not be the ultimate path to boosting nitric oxide after all:

  1. Acute L-arginine alpha-ketoglutarate supplementation fails to improve muscular performance in resistance trained and untrained men. J Int Soc Sports Nutr. 2012 Apr 17;9(1):17. doi: 10.1186/1550-2783-9-17.
  2. Bolus arginine supplementation affects neither muscle blood flow nor muscle protein synthesis in young men at rest or after resistance exercise. J Nutr. 2011 Feb;141(2):195-200. doi: 10.3945/jn.110.130138. Epub 2010 Dec 29.
  3. Vanhatalo A, et al. No effect of acute L-arginine supplementation on O₂ cost or exercise tolerance. Eur J Appl Physiol. 2013 Jul;113(7):1805-19. doi: 10.1007/s00421-013-2593-z. Epub 2013 Feb 20.


Q: So if our bodies produce L-Arginine on their own, what can we do to maximize nitric oxide for more muscular endurance and larger pumps at the gym?

A: Inhibit the enzymes that breakdown nitric oxide (AgmaPure™), support L-Arginine synthesis by the body (L-Ornithine HCl) and slow down L-Arginine breakdown (L-Norvaline.) Then to top it off, take the highest concentration glycerol ingredient you can get your hands on (Hydromax™.)


HYDROMAX™, high concentration glycerol.

  • 25% more glycerol than glycerol monostearate.
  • Supports cell volumization and growth.
  • May promote nutrient delivery.
AGMAPURE™ Agmatine Sulfate
  • The industry’s leading ingredient for promoting nitric oxide and pumps.
  •  Inhibits NOS (nitric oxide synthase) which are enzymes that catabolize nitric oxide production.
  • Premium grade Agmatine Sulfate free from the harmful chemical Arcaine that is typically occurring as a result of Agmatine Sulfate production.
Pre-Workout Support
  • L-Norvaline is included to support the inhibition of L-Arginine breakdown.
  • Features L-Tyrosine & Choline Bitartrate for stimulant free focus or increasing the intensity of your favorite pre-workout.
  • L-Ornithine HCl supports L-Arginine synthesis by the body.
