Pump Enhancer*

Pump Boost Container

3 Key Factors

  • Supports Enhanced Nitric Oxide Production & Cell Volume*
  • Promotes Elevated Muscle Pumps & Training Endurance*
  • Stimulant Free for Ultimate Versatility*

The Science Of Pump Boost

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.*

Taste terrific, i'm a begging body builder, and I definitely feel the "pump" in the muscle group worked. Only reason for a 9 is the mixture takes a bit of mixing before completely dissolved. Worth every cent otherwise.

Based on comparing adding pump boost versus pre workout alone, this definitely helps with pump and vascularity. My only complaint would be that the mechanisms to promote pump are similar to high end pre workouts. For example, I use Jym pre workout. It provides citrulline and coconut water powder, both found in pump boost. It would be nice to see ancillary or alternative pathways to pump explorer like aakg, a marine, etc. Not that the chosen ingredients don't work, they certainly do, but one gets the feeling you're just increasing quantity of ingredients you're already getting in a pre workout.

I love this product for lifting. I appreciate that it doesn't have caffeine added as I usually mix it with a pre-workout that already has a stimulant in it. I have purchased this several times already, but will continue to only get the unflavored as it's easier to mix that way.

I bought unflavored to mix with water before and to start a workout. Works great. Gives added energy with no side effects or crashing post workout. I would recommend.
