Great preworkout
"Great pre-workout for anyone that works out at night. Gives you the pump for the workout without keeping you awake afterwards if you have to sleep after."
RAW Nutrition Pump Non-Stim Pre-Workout, formulated by Chris Bumstead (CBum), is a versatile, 100% stimulant-free pre-training formula that can be stacked with a caffeinated pre-workout or taken solo. Built around a combination of powerful vasodilators and nitric oxide enhancers — 2,500mg L-Citrulline, 750mg Nitrosigine® (inositol-stabilized arginine silicate), 750mg Agmatine Sulfate, and a heavy 790mg combined dose of Himalayan Pink Salt electrolytes — Pump engorges your muscles with fresh blood, oxygen, and nutrients for massive fullness and vascularity. Beyond pump, the formula adds 2,500mg Betaine Anhydrous and 1,000mg Beta-Alanine for cellular hydration and muscular endurance, 1,000mg L-Tyrosine and 150mg Lion's Mane Extract for mental clarity and focus, and 750mg L-Taurine for hydration and recovery. This stim-free formula comes in clutch for the night owls who enter the iron dungeon late into the day and must avoid caffeine to get a good night's rest — no crash, no jitters. Mix 1 scoop with 6-8oz of water 20-30 minutes before training. Start with 1 scoop to assess tolerance; adjust to 2 scoops based on gym performance and goals. 40 servings per container.†

L-Citrulline is an amino acid that, once absorbed, is efficiently converted into L-Arginine and used for nitric oxide production — at 2,500mg, this is a meaningful contribution to the formula's overall vasodilation effect. Nitrosigine® (Inositol-Stabilized Arginine Silicate) is a patented complex of bonded Arginine Silicate shown to boost nitric oxide levels far superior to Arginine alone — the inositol stabilization specifically improves Arginine's otherwise poor oral bioavailability. Agmatine Sulfate is a powerful compound that stimulates nitric oxide production more potently compared to Arginine directly, while also possessing documented neuroprotective and anti-anxiety properties. Together, these three ingredients target the nitric oxide pathway from three distinct, complementary mechanisms rather than relying on a single compound.†
At 2,500mg, Betaine Anhydrous sits within the researched range for supporting cellular hydration and power output — betaine functions as an osmolyte, pulling water into cells for a fuller, more supported feeling during heavy lifts. Beta-Alanine at 1,000mg buffers intramuscular acid buildup during high-intensity training, though this dose is below the 3.2g standard clinical dose most commonly cited in endurance research — meaningful, but a more moderate contribution than a beta-alanine-focused product would provide.†
Lion's Mane is typically touted for its beneficial effects on brain health, and at 150mg contributes to the formula's mental clarity claims, alongside secondary benefits for immune health and nitric oxide balance. L-Tyrosine at 1,000mg is the direct precursor for dopamine and norepinephrine, supporting focus and mental drive without any stimulant mechanism. L-Taurine at 750mg is an amino sulfonic acid with documented roles in hydration, cellular osmolyte balance, and recovery — rounding out the formula's non-stimulant approach to focus and endurance.†
Between the dedicated 500mg Himalayan Pink Salt inclusion and the additional Chloride (290mg) and Sodium (210mg) sourced from Himalayan Pink Sea Salt in the mineral panel, Pump delivers a substantial combined electrolyte dose — supporting fluid balance, nerve signaling, and muscle contraction during training, particularly relevant for anyone training in heat or with heavy sweat loss.†
Pump is specifically built for two use cases. First, night owls who train late into the day and must avoid caffeine to get a good night's rest — Pump delivers the full pump, hydration, and non-stimulant focus experience without any risk of sleep disruption. Second, stacking: Pump can be combined with your favorite caffeinated pre-workout to enhance blood flow and nutrient delivery on top of whatever stimulant formula you're already using, without adding to your total caffeine intake. Either way, there's no crash or jitters, since the formula contains zero stimulant compounds.†
Can Pump Non-Stim be stacked with Thavage or another CBum pre-workout?
Yes — this is one of Pump's primary intended use cases. Since it's completely stimulant-free, it can be added to a stimulant pre-workout like Thavage to enhance blood flow and pump without increasing total caffeine intake.†
Should I start with 1 scoop or 2?
Start with 1 scoop to assess tolerance. Based on gym performance and goals, you may wish to move up to 2 scoops for a more pronounced pump and hydration effect.†
Is this the same as RAW Nutrition's Pump2 product?
No — Pump2 is a dedicated liquid glycerol supplement for hydration and muscle fullness. Pump Non-Stim Pre-Workout is a broader multi-ingredient formula covering nitric oxide production, endurance, hydration, and focus in one product, though the two can be stacked together for an even more comprehensive pump protocol.†
Is Pump Non-Stim appropriate for tested athletes?
Based on the disclosed formula — L-Citrulline, Betaine Anhydrous, Beta-Alanine, L-Tyrosine, Nitrosigine, Agmatine Sulfate, L-Taurine, Himalayan Pink Salt, and Lion's Mane — Pump Non-Stim does not appear to contain compounds prohibited by WADA or NCAA. Tested athletes should review the complete label and verify with their governing body as standard practice.†
Mix 1 scoop with 6-8oz of water 20-30 minutes prior to training. Start with 1 scoop to assess tolerance; may increase to 2 scoops based on goals and gym performance.
