Pump'd - massive pumps through nitric oxide support. Hyrdomax Glycerol – a high concentration glycerol to promote muscle volume AgmaPure Agmatine sulfate- Arcaine-free, premium quality Agmatine sulfate features a pre-workout support blend. Promotes increases in nitric oxide. Increase in N.O. during exercise may promote vascularity, muscular endurance and intense pumps. Pump'd has been formulated by Betancourt Nutrition's product development team to be more than just a muscle volumizer, it is a stimulant free performance enhancer. Promoting muscle volume alone is not enough to support growth and it does nothing to boost muscular endurance during exercise. The ideal 'pump' product will promote the release of nitric oxide in conjunction with exercise for the purposes of boosting performance as well as muscle volume and vascularity. This is where Pump'd excels in comparison to the competition: AgmaPure an Agmatine Sulfate that is free from the harmful chemical Arcaine that is typically occurring in Agmatine Sulfate product. HydroMax Glycerol yields more glycerol per serving than glycerol monostearate for maximizing muscle volume.
