Psycho Pharma Edge Pump is a stimulant-free pump and hydration formula built around a simplified, high-dose approach: 4,000mg of pure L-Citrulline per scoop (8,000mg at the full 2-scoop serving) alongside 1,000mg of HydroPrime Glycerol Powder (65% concentration) for cellular hyperhydration, 25mg of AstraGin for absorption enhancement, and Pink Himalayan Salt for sodium and chloride electrolyte support. Zero stimulants — ideal for nighttime workouts, taking a break from stims, or stacking with Edge of Insanity to create what Psycho Pharma calls the "SUPER PRE." Mix 1 scoop with 4-6oz water 20-30 minutes before training, or 2 scoops with 8-12oz water for maximum results. Do not exceed 2 scoops daily. 40 servings (single scoop) or 20 servings (double scoop) per container. Flavors: Vein Nectar and Veinorade. Manufactured in a facility that processes milk, eggs, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. California Prop 65 Warning applies.†

Edge Pump — A Reformulated, Simplified Approach
Edge Pump's current formula reflects a deliberate simplification from earlier versions of the product, which combined L-Citrulline Malate, Glycerpump, Taurine, Agmatine Sulfate, Inositol-Enhanced Arginine Silicate (nooLVL), and S7 into a six-ingredient stack. The current formula strips this down to four core actives at meaningfully higher individual doses: pure L-Citrulline (not diluted with Malic Acid the way Citrulline Malate is), a full-strength HydroPrime Glycerol dose, AstraGin for absorption, and Pink Himalayan Salt electrolytes. The result is a formula built around fewer, higher-dosed ingredients rather than a longer list of moderate-dose compounds — the same design philosophy trend seen across several premium stim-free pump products in 2025-2026.†
The Formula — What Each Ingredient Does
L-Citrulline — 4,000-8,000mg — Pure Citrulline, No Dilution
Edge Pump uses pure L-Citrulline rather than Citrulline Malate — a meaningful distinction for total active Citrulline content. Citrulline Malate at a 2:1 ratio delivers roughly two-thirds actual Citrulline by weight, with the remaining third being Malic Acid. Edge Pump's 4,000mg per scoop (8,000mg at 2 scoops) is 100% Citrulline — no diluting Malic Acid content. Citrulline converts to Arginine in the kidney, providing substrate for eNOS-mediated nitric oxide production, vasodilation, and the pump and blood flow improvements that define the pump training category. At the full 2-scoop 8,000mg dose, Edge Pump delivers one of the higher pure Citrulline doses available in a stim-free pump product.†
HydroPrime Glycerol — 1,000-2,000mg — Cellular Hyperhydration
HydroPrime is a trademarked glycerol powder standardized to 65% glycerol concentration — dramatically more concentrated than standard glycerol monostearate (GMS) powders, which typically contain only 1.5-25% actual glycerol depending on formulation. Glycerol is a potent osmolyte that draws water into and around muscle cells through osmotic pressure, producing a state of cellular hyperhydration distinct from the vascular pump that Citrulline's NO pathway produces. At 1,000mg of a 65%-concentration extract per scoop (650mg actual glycerol), and 2,000mg at the full serving (1,300mg actual glycerol), Edge Pump adds the intracellular "water pump" dimension alongside Citrulline's vascular pump — producing the fuller, rounder muscle appearance that combining both mechanisms is known for.†
AstraGin — 25-50mg — Absorption Enhancement
AstraGin (NuLiv Science's patented combination of Astragalus membranaceus and Panax notoginseng root extracts) upregulates intestinal nutrient transporter proteins, improving the absorption rate of amino acids and other bioactive compounds. In Edge Pump specifically, AstraGin supports more complete absorption of the high-dose Citrulline and glycerol content — ensuring more of the stated 4-8g Citrulline dose actually reaches systemic circulation rather than being partially wasted in GI transit.†
Pink Himalayan Salt — Sodium and Chloride Electrolyte Support
Pink Himalayan Salt provides the sodium (58-115mg) and chloride (86-171mg) electrolyte content in Edge Pump. Sodium is the primary extracellular electrolyte governing fluid balance and neuromuscular membrane potential during training — its inclusion alongside glycerol's hyperhydration effect supports the overall fluid retention and hydration status that both compounds work toward. Pink Himalayan Salt also carries trace minerals beyond standard sodium chloride, though the primary functional contribution here is the sodium and chloride electrolyte support itself.†
Stacking Edge Pump — The "Super Pre" Combination
Edge Pump is specifically designed as a stackable pump enhancer for Psycho Pharma's other pre-workout products. Adding 1-2 scoops of Edge Pump to a scoop of Edge of Insanity is Psycho Pharma's recommended "Super Pre" combination — layering Edge Pump's high-dose Citrulline and glycerol on top of Edge of Insanity's stimulant and Citrulline Malate base for maximum combined pump without doubling stimulant intake. Edge Pump can also be stacked with Psycho Pharma's mild-stimulant cognitive focus products for a pumped, focused training experience without high-stim intensity. Used standalone, Edge Pump is ideal for nighttime training, stimulant tolerance breaks, or any session where pump and hydration are the priority without any energy component.†
Frequently Asked Questions
Why does Edge Pump use pure L-Citrulline instead of Citrulline Malate?
Pure L-Citrulline delivers 100% of the stated weight as actual Citrulline, while Citrulline Malate (commonly used at a 2:1 ratio) delivers only about two-thirds actual Citrulline, with the remainder being Malic Acid. At 4,000-8,000mg, Edge Pump's pure Citrulline provides more total active Citrulline than an equivalent stated weight of Citrulline Malate would.†Can Edge Pump be stacked with Edge of Insanity?
Yes — this is one of Edge Pump's primary intended use cases. Psycho Pharma specifically recommends adding 1-2 scoops of Edge Pump to a scoop of Edge of Insanity to create what they call the "Super Pre" — maximizing pump and hydration on top of Edge of Insanity's stimulant and focus profile, without adding any additional caffeine or stimulant load.†Has Edge Pump's formula changed recently?
Yes. Earlier versions of Edge Pump used a six-ingredient formula including Citrulline Malate, Glycerpump, Taurine, Agmatine Sulfate, Inositol-Enhanced Arginine Silicate (nooLVL), and S7. The current formula simplifies to four core actives — pure L-Citrulline, HydroPrime Glycerol, AstraGin, and Pink Himalayan Salt electrolytes — at higher individual doses. If you've used Edge Pump previously and don't recognize this ingredient list, this reflects the updated formulation.†Is Edge Pump appropriate for tested athletes?
Based on the disclosed formula — L-Citrulline, HydroPrime Glycerol, AstraGin, and Pink Himalayan Salt — Edge Pump does not contain any compounds prohibited by WADA or NCAA. Zero stimulants, no banned compounds of any kind. Tested athletes should review the complete label and verify with their governing body as standard practice.†
