High Volume is a specific PEScience product
High Volume is PEScience’s stimulant-free pump pre-workout. The product name is easy to confuse with high-volume training, but the supplement has a defined formula. The current manufacturer page describes it as caffeine-free and beta-alanine-free, making stimulant content a useful first distinction from many conventional pre-workouts.
Read “36 scoops” correctly
The inspected Guava Pineapple Punch Supplement Facts panel defines a serving as two scoops, totaling 15 g. That makes the 36-scoop tub 18 full label servings. Per two-scoop serving it lists:
- L-citrulline: 6,000 mg.
- Arginine nitrate: 2,000 mg.
- Performance and Hydration Matrix: 3,925 mg, containing taurine, trisodium citrate, magnesium glycerophosphate and HydroMax glycerol powder.
- Vitamin C: 250 mg; magnesium: 50 mg; sodium: 250 mg.
The matrix does not provide an individual amount for each constituent. Do not present its 3,925 mg combined weight as a glycerol or taurine dose. Likewise, the prominently advertised 6 g citrulline belongs to the two-scoop serving; a single scoop supplies half that amount.
What “pump” can and cannot tell you
Citrulline participates in the pathway to nitric oxide, but a mechanism is not a guarantee of better workouts. The NIH Office of Dietary Supplements describes performance evidence for citrulline as limited and mixed. It is reasonable to compare disclosed ingredients and doses; it is not reasonable to promise more muscle or a fixed increase in repetitions from this tub.
High Volume’s 6 g figure is L-citrulline, not 6 g of a citrulline-malate mixture. Keep those ingredient forms separate when comparing labels. Caffeine-free also does not mean interaction-free or suitable for everyone.
Practical buying and mixing checks
PEScience lists one to two scoops mixed with 8–12 oz water about 30 minutes before exercise. Follow the directions and warnings on the container you receive. If using another supplement, check overlapping ingredients and the combined serving rather than assuming every pump-and-energy stack has been studied.
Compare cost per intended serving, not merely the number printed beside “scoops.” This explanation follows the current 36-scoop formula shown by PEScience. Older labels or retailer summaries can describe a different serving or composition, so match the actual panel before transferring ingredient figures.
