RSP Pump Boost is formulated with HydroMax®, a highly concentrated and stable blend of glycerol and silica. This unique form of glycerol is the most potent version available, containing over 65% free molecular glycerol while traditional glycerol monostearate is only 5-12% concentrated. It is one of the most beneficial ingredients for pumps as it easily absorbs into the intracellular space, increasing the concentration of fluid in the blood and muscle tissue. Not only does this maximize the cell volume for pumps, but it also promotes hyperhydration which brings benefits for endurance and stamina events including environmental adaptation to heat, humidity and stress. Pump Boost is further enhanced with L-Citrulline which is a precursor of nitric oxide for maximizing your pump.
