Prepare to feel the volume
We’ve all experienced the pump - that feeling of your muscles blowing up after doing a set of intense lifts during your workout. You do the sets, you feel the fullness of your muscles and see your arms swell in front of you, but within minutes of concluding your workout, you lose the pump. That’s just how it is, and how it’s always been. Until now.
- The Best Pumps You've Experienced*
- Feel Great During Your Workout*
- Pumps For Hours*
- Loaded With L-Citrulline*
We wanted to take the “pump product” category and permanently turn it on its head. And after over a year of diligent research and development, we have finally created a product that doesn’t just stop working 5 or 10 minutes after your workout; High Volume is the first ever product in the category with a formula focused on long lasting pumps.*
L-Citrulline is one of the best N.O. ingredients on the market, but it is constantly used at tiny serving sizes. Stop wasting your money on citrulline malate in a pre-workout product -you need pure L-Citrulline. The citrulline malate found in most products is a blend of L-Citrulline and L-Malate. That means, the 4 grams of L-Citrulline that is found in High Volume is equivalent to the citrulline content in 8 grams of citrulline malate! That’s what we do at PES - we give you more of what you need.*
Remember, the key is to increase N.O., do it quickly, and have the pump last past the end of your workout. In our search for a long-lasting pump ingredient, we focused on the compound nitrate. Not just any nitrate, but a patented amino nitrate. Nitrate, in addition to having an 8 hour half-life, uses a unique pathway to boost N.O. 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 activity. This means that you are not limited to only the pump of L-Citrulline and other ingredients using its mechanism with the combination of nitrate and L-Citrulline. Nitrate acts as an “N.O. donor,” meaning it converts to N.O. directly via a 2-step process called the nitrate-nitrite-nitric oxide pathway - no enzymes or restriction points involved! Some of you might be asking why we use Arginine Nitrate as the source out of all possible amino-nitrates? Easy answer - the nitrate is increasing N.O., but the arginine plays a very important role when combined with nitrate. In an in-vitro study, scientists found that arginine may have the ability to reduce nitrate tolerance! In our opinion, this makes Arginine Nitrate the best form of nitrate to take.*
Why High Volume?
You have never experienced anything like this. Every product tells you that, but what company continues to deliver? We don’t put our money in mass marketing, we put it into developing the best product for the consumer. If you’ve been following science closely, you don’t need me to tell you that. High Volume users are coming out of their workouts unable to reach their arms over their heads from the massive pumps! The best quote we got from one of our initial users was, “I think my pumps got pumps!” Once you experience High Volume, you will call every other pump product flat. It’s time to feel the volume and get with the brand that brings the formulas that set the standard. You’ll look forward to your next workout knowing you’ll walk out of the gym looking like a bigger version of the guy who walked in. You’ll constantly want to train another group of muscle to see what High Volume will do next. This is the product that has redefined the pump category permanently.*
