Synergistic n.o. booster stacks - we enhanced a blend of L-Arginine AAKG & HCL with L-Citrulline Malate (converted to Arginine in the body), which is a combination clinically shown to increase Arginine blood levels more than supplementation with Arginine alone.

2X more than competitors - our 2500 mg serving size is 50 - 100% stronger than other leading brands in pill form. Competitor dosage ranges (1000mg - 1500mg) have been shown in numerous studies to be largely ineffective in promoting nitric oxide production.

High dosage without the powder - combines 2500 mg’s of vital Nitric Oxide precursors: L-Arginine (AAKG & HCL) & L-Citrulline Malate, creating a high dose NO booster in convenient tablet form - avoid cumbersome shake mixing and messy powder without sacrificing the dosage necessary for optimal pump, growth & endurance.

Doctor-driven, science-backed - bringing Dr. Emil’s unique knowledge as both a medical doctor & recognized authority in the supplementation field (he’s also a former pro athlete!), our blends are painstakingly formulated to provide superior results and are always backed by science - free of gimmicks, fads & false promises.
