Psycho Pharma Psycho Syrup is a stimulant-free liquid pump formula built around 10g of Glycerol per serving — up to 5x more glycerol than many traditional pump powders — alongside 1,500mg L-Citrulline, 750mg Agmatine Sulfate, and 500mg L-Arginine. The liquid delivery format eliminates the mixing, clumping, and gritty texture that glycerol-based powders are notorious for, delivering true hyperhydration and skin-splitting pumps in a fast, simple capful dose. 40 calories per serving. Zero caffeine. Take standalone for a pure pump experience, or stack with Edge of Insanity or VITALS for combined pump and energy support. Purple Drank flavor. 32 full-cap servings or 40 half-cap servings per bottle, depending on dosing protocol. California Prop 65 Warning applies.†

Why Psycho Syrup Exists — Solving the Glycerol Powder Problem
Glycerol has become one of the most sought-after pump ingredients in the supplement industry over the past several years, prized for its ability to draw water into muscle cells and produce a genuine state of cellular hyperhydration — the "skin-splitting" pump that vascular athletes specifically chase. But glycerol has a well-known formulation problem in powder form: it is intensely hygroscopic, meaning it absorbs moisture from the air aggressively. This is the origin of the supplement industry phrase "no clumps, no pumps" — glycerol-containing powders are notorious for turning into hardened bricks in the tub within weeks of opening, especially in humid environments.†
Psycho Pharma's solution is to skip the powder format entirely. By delivering 10g of glycerol per serving as a liquid, Psycho Syrup eliminates the clumping problem at its source — there's no powder to absorb moisture because the product is already in solution. The liquid format also allows for a meaningfully higher glycerol dose than most pump powders can practically achieve without becoming unusable — up to 5x more glycerol than many traditional pump powders, delivered in a format that pours cleanly and mixes instantly into water with zero clumping risk.†
The Formula — What Each Compound Does
Glycerol — 10g — True Hyperhydration
Glycerol pulls water into muscle cells for deep cellular hyperhydration — an osmotic mechanism distinct from the vascular pump that nitric oxide compounds produce. While NO-driven pump comes from increased blood volume in the vasculature surrounding muscle, glycerol's hyperhydration works at the intracellular level, drawing water directly into the muscle cell itself. At 10g per serving, Psycho Syrup delivers a clinically meaningful glycerol dose — well above the levels found in most pump powders that are limited by clumping concerns to lower doses. This concentrated liquid delivery is what produces the "skin-splitting" pump character that Psycho Syrup is specifically marketed around.†
L-Citrulline — 1,500mg — NO-Driven Vasodilation
L-Citrulline converts to Arginine in the kidney, providing substrate for eNOS-mediated nitric oxide production — the vasodilation mechanism that increases blood vessel diameter and blood flow to working muscle. At 1,500mg, Psycho Syrup's Citrulline dose is positioned as a complementary addition to the glycerol-driven hyperhydration rather than a standalone maximal pump dose — for athletes seeking the full clinical 6-8g Citrulline dose alongside Psycho Syrup's glycerol and hydration benefits, stacking with a Citrulline-forward product like VITALS or Edge of Insanity provides more complete NO pathway coverage.†
Agmatine Sulfate — 750mg — Sustained Pump Duration
Agmatine helps keep that pumped feeling going, even after your workout ends. Agmatine — the decarboxylated metabolite of arginine — inhibits arginase (the enzyme that degrades arginine before it can reach eNOS for NO synthesis) and directly activates imidazoline receptors for vasorelaxation through a separate, NO-independent pathway. This dual mechanism is specifically why Agmatine is associated with extended, longer-lasting pumps compared to Citrulline or Arginine alone — it both supports ongoing arginine availability and produces its own independent vasodilatory signal that persists beyond the immediate post-dose window.†
L-Arginine — 500mg — Direct eNOS Substrate
While Citrulline provides sustained arginine generation through the kidney conversion pathway, L-Arginine at 500mg provides direct substrate for immediate eNOS activity — the fast-acting complement to Citrulline's slower, sustained delivery. Together, the Citrulline, Agmatine, and Arginine combination addresses better blood flow to muscles through multiple complementary mechanisms, helping more blood reach working muscle for a strong, pumped-up look during training.†
Standalone or Stacked — How to Use Psycho Syrup
Psycho Syrup is positioned as full pumps, vascular pumps, non-stim — take standalone or stacked with Edge of Insanity. Used alone, Psycho Syrup delivers a pure, stimulant-free pump and hydration experience appropriate for late-night training, caffeine-sensitive athletes, or anyone who wants pump support without any energy or focus compounds attached. Stacked with a stimulant pre-workout like Edge of Insanity or VITALS, Psycho Syrup adds concentrated glycerol hyperhydration and additional pump compounds on top of whatever Citrulline and stimulant base the primary pre-workout already provides — without doubling up on caffeine the way stacking two full stim pre-workouts would.†
Frequently Asked Questions
Why is Psycho Syrup a liquid instead of a powder?
Glycerol is intensely hygroscopic — it absorbs moisture from the air, causing glycerol-containing powders to clump and harden in the tub over time (the source of the supplement industry phrase "no clumps, no pumps"). By formulating Psycho Syrup as a liquid, Psycho Pharma eliminates the clumping problem entirely and is able to deliver a higher, more concentrated glycerol dose (10g per serving) than most pump powders can practically achieve.†Can Psycho Syrup be stacked with Edge of Insanity or VITALS?
Yes — this is one of the product's primary intended use cases. Psycho Syrup contains zero stimulants, so stacking it with a caffeinated pre-workout adds pump and hydration support without doubling up on caffeine or stimulant compounds. Take Psycho Syrup alongside your regular pre-workout dose for enhanced glycerol-driven hyperhydration and additional pump compounds.†How many servings are actually in the bottle?
Serving count depends on dosing protocol — Psycho Syrup is dosed by capful, with some listings showing 32 servings at a full capful and others showing up to 40 servings when using a half-capful dose. Check the specific bottle label for exact serving size and count, and ask Get Yok'd staff if you need clarification on the current packaging.†Is Psycho Syrup appropriate for tested athletes?
Based on the disclosed formula — Glycerol, L-Citrulline, Agmatine Sulfate, and L-Arginine — Psycho Syrup does not contain any compounds currently prohibited by WADA or NCAA. Zero stimulants and no banned compounds. Tested athletes should review the full label and verify with their governing body as standard practice.†
How to Take Psycho Pharma Psycho Syrup
Take 1 serving (full capful or half capful per label directions) mixed into water, or consumed directly, 20-30 minutes before training. Can be taken standalone for a pure non-stimulant pump experience, or stacked with a caffeinated pre-workout like Edge of Insanity or VITALS for combined pump, hydration, and energy support. Zero caffeine — appropriate for any time of day including evening training. Stay well hydrated throughout the day when using glycerol-based products, as glycerol's hyperhydration effect increases total body water demand. Not for persons under 18. Not for pregnant or nursing women. Consult a physician before use if taking any prescription medications or having any medical condition. California Prop 65 Warning applies.†
