The King of Pumps — Zero Stimulants, Maximum Performance

Use High Volume as a standalone for pure pump and performance, or stack it with Prolific or Versa to add energy and focus on top of your pump foundation.

Who It's For

Training at night or caffeine-sensitive athletes
Those already getting caffeine from coffee, Versa, or Prolific
Anyone who wants elite pump and performance without stimulants

Leucine is the anabolic trigger.

Leucine is unique because it does not just act as a structural component of muscle tissue. Instead, it functions as a metabolic signal that tells the body to begin building new muscle protein.

Select Protein includes added PepForm leucine peptides to help maximize muscle building potential per scoop.

2 to 2.5 grams of leucine in a standard 20 to 25 gram scoop of protein

3 and 5 grams of leucine per meal is the threshold

PDCAAS: What It Means, and Why Your Label Might Not Be Telling the Truth

The problem is that not all protein is created equal. Scores range from 0.0 (very poor quality) to 1.0 (high quality).

The %DV is calculated using the formula: (Protein grams ÷ 50) × 100

Protein on the label 10 g Protein source

%DV on the label: 20%
Usable protein our math: 10 g
%DV after PDCAAS our math: 20%

If a product provides 10 grams of protein and lists 20% DV, the protein has likely been adjusted properly and has a PDCAAS close to 1.0. If that same product lists only 5% DV, you know the protein quality is much lower and the usable protein is overstated.

Common Proteins and Their PDCAAS

To qualify as a “good source,” a product must provide at least 5 grams of protein, or 10% of the daily value (DV), which is set at 50 grams. To qualify as an “excellent source,” it must provide at least 10 grams of protein.

For example, a product containing 10 grams of wheat gluten protein may list 10 grams on the label. But since wheat gluten has a PDCAAS of around 0.25, only about 25% of that protein is available to your body. In reality, it should be listed closer to 3 grams of usable protein.

This simple check can help you determine whether a product’s protein content reflects what your body can actually utilize.

Quality is more than a buzzword.

A fully developed quality system takes years to perfect and comes with a hefty price tag, causing many in the industry to fall short. We take pride in our commitments, and hold ourselves to the highest standards as we make products that our customers trust to put into their bodies every day.

20 years of experience lead our quality department in pharmaceutical, food, and supplement manufacturing practices.

Third-Party Audits: As part of our ongoing commitment to going above and beyond, we regularly have ourselves audited by a third-party quality control team, and we send third parties to audit any manufacturing partners we work with.
Raw Material Testing: An often skipped step in most quality programs, we start our testing at the raw material level. Before any ingredients are ever mixed or put into a bottle, they are analyzed for quality, purity, potency, and contaminants like heavy metals, microbes, mold, yeast, and pesticides.
Finished Product Testing: Once a batch of products is completed, it is then tested again to ensure the manufacturing process is a success. For example, if a product says it has 200 mg of caffeine, it is tested and validated for meeting that claim.
Heavy Metal Testing: Our raw materials and finished products are tested for the following heavy metals: Lead, Mercury, Cadmium, Arsenic
Pesticide & Herbicide Testing: We periodically conduct additional third-party testing for multiple pesticides and herbicides, including: Glyphosate, AMPA, Atrazine
Microbial Testing: Our raw materials and finished products are tested for: Yeast, Mold, Staph, E. Coli, Salmonella
PDCAAs: All of our protein products have been tested for their true protein content using a test called PDCAAs.
CoAs, Lab Partners & Transparency: Colmaric Analyticals, Mérieux NutriSciences, Eurofins Scientific, Analytical Resource Labs, Advanced Labs Inc, Medallion Laboratories.
NSF Audited Facilites: All of our powders and capsules are manufactured in NSF certified facilities, recognized as one of the strictest and toughest certifications to receive.
Sensory testing: No matter how many batches of a product we have made, every single new batch goes through full sensory testing by our quality team.

For 15 years, we have taken seriously the responsibility of creating products that customers put into their bodies every day to achieve their goals. At PEScience, we don’t just make products; we set new standards in nutrition.
