  • 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.*

I recommend this stuff for a couple reasons. This is a descent pre-workout while cycling off stimulants but I otherwise wouldn't take it as a standalone unless stimulants of any kind aren't your thing. Also, this stuff is amazing adding it to your primary stimulant pre-workout...you'll feel unstoppable. I'd use the unflavored version while using this product with another pre-

This was a very helpful much needed boost for my caffeinated preworkout. Although the unflavored version is really bitter however the peach mango is really really good. All in all I really loved this pump product, it was super effective.

Peach Mango - Is there a better flavor combo? Doubt it! I love the way this mix makes me feel before my workout, I feel pumped but not jittery. Gets me through a 55 minute spin class with enough left over to make it off the bike and back home. While it doesn't stay with me all day unless I'm drinking it all day, it gets the job done.

I add this into my workout drink and it gives me an awesome pump for the rest of the day and sometimes even into the next morning. Don't really want to workout without this anymore. RSP makes good products as well.

I bought the peach mango and it tasted fantastic! Been using it for about 2-3 weeks. I definitely can feel the pump at the gym. Only reason i knocked off a point is because it doesn’t mix too well in water. I always end up with particles at the bottom of the shaker even after mixing for a while, which would leave an after taste on my tongue cuz I refuse to throw away product, so I do add extra water at the end to mix and swallow those particles. I would buy this product again tho, cuz the taste is great.

Great taste, mixes with a couple shakes and gives that needed energy to power through a workout. I use sometimes as a pre-workout and sometimes as intra-workout. Works great either way.

RSP Pump Boost is an awesome product. I add one scoop to their Dyno preworkout, into a shaker cup of Gatorade and have had some amazing pumps ever since. No side effects, no upset stomach, just full muscles and the endurance to push through more reps where I would normally stop. Taste is great, price is great, no complaints at all. Highly recommended.

Ordered this to add to my pre workout. It works as described I had insane muscle pumps. I've had it with plain water as well it tastes like a tropical coconut blueberry concoction. Good stuff, I love RSP. They care about their customers on a different level than most supplement providers.
