High Volume: Caffeine-Free, Two-Scoop Serving
PEScience High Volume is caffeine-free and leaves out beta-alanine. The current Raspberry Lemonade panel lists two scoops, 15 g per serving, with 18 servings per tub. The pictured “36 scoops” is not 36 full two-scoop servings. Caffeine-free does not mean risk-free or automatically suitable to stack.
6 g L-Citrulline and 2 g Arginine Nitrate
That two-scoop serving supplies 6 g L-citrulline and 2 g arginine nitrate (NO3-T). The arginine-nitrate amount is not 2 g pure nitrate. These quantities identify the formulation; they do not prove greater pumps than another complete product.
The panel also lists a 3,925 mg Performance & Hydration Matrix containing taurine, trisodium citrate, magnesium glycerophosphate and HydroMAX glycerol 65%. Individual amounts are undisclosed. Its mineral declarations include 250 mg sodium and 50 mg magnesium; those are not extra amounts to add to the blend’s weight.
No Beta-Alanine Is Not a Flaw
High Volume does not include beta-alanine on this panel. That is a formulation choice, not proof that nobody will experience tingling or other adverse effects. It also means you cannot count this serving toward a beta-alanine intake merely because it is sold as a pre-workout.
Read the Nitrate Warnings
The manufacturer’s warning says not to use High Volume with erectile-dysfunction medication or additional nitrate medication/supplements, and to consult a physician, particularly with medications or pre-existing conditions. Its lack of caffeine does not remove those restrictions.
High Volume vs PUMP-OCALYPSE

The inspected PUMP-OCALYPSE Blueberry Pomegranate panel lists 3.5 g HydroPrime glycerol powder standardized to at least 65% glycerol, 3 g L-citrulline, 1 g PeakO2, 1 g arginine HCl, 500 mg agmatine sulfate and 500 mg betaine per 12.4 g scoop. The 3.5 g figure is powder material, not 3.5 g pure glycerol.
High Volume discloses more L-citrulline per labeled full serving: 6 g versus 3 g. Its individual glycerol amount is undisclosed, so the claim that PUMP-OCALYPSE supplies “much more glycerol” cannot be verified. Neither difference proves superior fullness, hydration or performance.
