PEScience High Volume

We’ve all experienced the muscle pump… that feeling of your muscle bellies blowing up after completing a set of intense lifts during your workout. You do these sets, you feel the muscle fullness and see your biceps, trices and other muscles swell in front of you, but within minutes of finishing your workout, you lose the pump. That’s just how it is, and how it’s always been. Until now…

Changing The Game

At PEScience, we’ve done some pretty groundbreaking stuff and have been the first brand to bring you a handful of novel and now very popular ingredients to the market. But we wanted to do something different here with High Volume. We wanted to take the nitric oxide “pump product” category and change it forever, permanently turning it on its head and leaving all other products in the dust. After over 12 months of in-depth research and development, we at PES have finally created a product that doesn’t just provide you with a pump that lasts 5 or 10 minutes after you've finished workout, but High Volume is the first ever product in its category with a formula slely focused on long lasting pumps!

Let’s take a closer look at High Volume and see how we achieved what was once deemed impossible…

Pure L-Citrulline (no Malate here…)

L-Citrulline is one of the best Nitric Oxide (NO) boosting ingredients on the market, but it is constantly used at tiny serving sizes that will never be effective.

But stop wasting your time and money on Citrulline Malate in a pre-workout product. You need Pure L-Citrulline for the best up. The citrulline malate found in products is just a blend of L-Citrulline and L-Malate. So that means that the 4 grams of L-Citrulline that is found in High Volume is equivalent to 8 grams of citrulline malate! That’s what we do at PES… we give you more of what you need.

Nitrates – Pumps for hours?!

Remember… the key is to increasing Nitric Oxide is to do it quickly, and have it last way past the end of your workout. In our search for a long-lasting pump boosting ingredient, we focused on the compound known as nitrate. Not just any nitrate, but a powerful patented amino nitrate! 

Nitrate, on top of having an 8 hour half-life, uses a unique pathway to boost Nitric Oxide [8]. To be specific, nitrates bypass the enzyme that L-Citrulline relies on, eNOS, which has a “saturation point” at which no further concentration can increase its means of action. This means that you aren't limited to only the pump of L-Citrulline and other ingredients that get stoped in their tracks due to eNOS. You see, nitrate acts as an “NO donor,” meaning it converts to NO directly via a 2-step process called the nitrate-nitrite-nitric oxide pathway…no enzymes or restriction points involved [7]!

Some of you might be asking, why did we use the ingredient Arginine Nitrate as our nitrate source out of all the possible amino acid nitrates to choose from? Easy answer… the nitrate bond is increasing NO, but the amino acid arginine plays a very important role when combined with it. In an in-vitro study, scientists discovered that arginine may have the ability to reduce nitrate tolerance [4]! In our opinion, this makes Arginine Nitrate the best form of nitrate to take as it's effectiveness is longer lasting due to this.

Nitric Oxide – A New Pathway For Muscle?

For a long time, it’s been a near mystery whether or not “the pump” actually improves muscle development. Recent research done in-vitro now suggests that nitric oxide (NO) may have a part in building lean muscle [1-3]. This has not yet been studied in human trials, but it is definitely something we are keeping an eye on for future development.


A few months ago AmentoMAX was released as a single ingredient product. As we expected, it quickly took off with popularity and raving fans for its pre-workout use. So of course, we knew we had to use AmentoMAX here in High Volume, to bring the unique angle to every workout.

The final trigger in muscle contraction is an increase in calcium in the muscle cell. The calcium binds to key muscle proteins that result in contraction, and it has been shown that the more calcium released into the muscle cell, the more force is produced.

While not studied yet directly in humans, Amentoflavone possesses the highly unique ability to increase calcium release, in vitro [7]. In fact, essentially only one other commonly found compound shares this mechanism: caffeine. This increase in muscular calcium concentration is part of the reason why caffeine is an ergogen (capable of improving exercise performance). 
Amentoflavone will not give the same physical stimulation as caffeine, making it a perfect fit in this stimulant-free formula.

HydroMax® and Taurine – High Volume Achieved

HydroMax® is a high potency glycerol compound. Glycerol is an ingredient that gets transported to your plasma after ingestion…and it doesn’t leave the plasma for a long time. While in the plasma, glycerol sucks up water by acting as a sponge. People love Glycerol for the pump/fullness feel it gives them, but have hated it for the gritty texture it has in their cup. It could be like drinking sand! Until HydroMax® solved that nasty little problem.

Taurine is a compound that localizes primarily to the intracellular muscle, and like glycerol, where taurine goes, water follows. This makes taurine a great compound to complement HydroMax®.

You have never experienced anything like this before. Every product might tell you that… but we at PES deliver! We don’t put our money in mass marketing, instead we put it into developing the best product we can for the consumer. If you’ve been following the clinical science closely, you don’t need me to tell you that High Volume has users coming out of their workouts unable to reach their arms over their heads due to the massive hard pumps! The best quote we got from one of our initial users was, “I think my pumps got pumps”!

Once you experience PES High Volume, you will call every other pump nitric oxide booster flat. It’s time to FEEL THE VOLUME, and get with the brand that brings formulas that set the standard above all.

You’ll look forward to your next training session knowing you’ll walk out of the weight room looking like a bigger version of the guy who walked in. You’ll constantly want to train another group of muscle just to see what High Volume will do next.

This is the product that has redefined the pump category permanently.

This is PES High Volume
