Formula: Contains: HydroMax glycerol powder 65% S7 Nitrosigine Bonded Arginine Silicate
Formula: Contains: Nitrosigine supports increased blood flow and enhanced pumps so you can power through workouts with extended energy and stamina. Citrulline converts arginine to Nitric Oxide (NO) to help increase your pump. Agmatine sulfate helps prevent NO breakdown so you can enhance your training time to improve endurance. Added minerals help your muscles contract so you can build your body the way you want. S7 supports increased NO production, and helps widen blood vessels by as much as 50% for extreme vascularity and endurance.
Formula: Contains: HydroMax helps hydrate your muscles to support longer workouts and increased muscle pump and fullness. L-Orthinine breaks down fatigue-promoting metabolites and promotes longer and harder training.
Formulation: Does NOT Contain: Stimulant-free Stimulants can constrict the blood vessels. Having stimulants in a NO product can be counter-productive. MRI's NO2 Black Muscle+Pump is stimulant-free so you can optimize pumps without interference.
