  • 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.*

Peach mango tasted great. The pump boost also gave that extra bit of energy to keep going for a couple more reps. Also picked up the unflavoured but haven't tried it yet. Only reason 9 stars is because of some chalkiness. Will buy again.

Really great taste - true to description. Gave me a seriously great leg workout since I stopped taking stim-preworkout. Only reason i didn’t give a 10 is a very, very SLIGHT chalky residue when mixing. However I also mixed in my creatine with it so that could have been this issue. Great product. Enjoying it so far!

Love mixing any of these with my pre workout. The pump is real and definitely helps get the extra reps up to finish strong. It mixes super easy and comes through for late workouts when I want to avoid caffeine.

I bought unflavored so I can mix it with my pre workout (AminoLean). This product makes me feel like I can’t do another rep. My chest and arms feel so FULL and TIGHT after a workout. It gives me the feeling I’ve been missing. I’m 46 and don’t feel those teenage pumps I used to feel. But, now I can. Great produce in my eyes!!

Really good taste. I mix it with amino lean after easier workouts to keep my vascularity high. Only complaint is it never fully mixes

I love the taste of the peach mango. It’s not chalky like some pre-workouts I’ve taken in the past. It also gives me a good boost when it’s been a long day, but doesn’t give me the jittery feeling either. I would continue to buy this product and recommend it to anyone looking for a boost!
