1. PEScience High Volume Stim-Free — Premium Pump Performance
PEScience High Volume is the gold standard for caffeine-free pre-workouts. The formula stacks 8g of l-citrulline (yes, eight grams — most pre-workouts use 4-6g), 1g of taurine, agmatine sulfate, and glycerol monostearate (HydroMax™) for cellular hydration and prolonged pumps. 36 servings at $54.99 works out to under $1.55 per serving for a premium-grade product.
Best for: Serious lifters, evening trainers, anyone who's tried other stim-free pres and found them weak. Buy: PEScience High Volume at Top Nutrition & Fitness.
2. Mammoth Pump (30 servings) — Budget-Friendly Daily Pump
Mammoth Pump delivers a solid pump at a budget-friendly $39.99 for 30 servings ($1.33/serving). Citrulline malate, agmatine, beetroot extract, and electrolytes for hydration support. Lighter on muscle-volume ingredients than PEScience High Volume, but a fraction of the price for daily use.
Best for: Daily users who train 5-6x/week, lifters new to stim-free pre-workouts. Buy: Mammoth Pump 30 servings.
3. Mammoth Pump (60 servings) — Best Value Per Serving
Same Mammoth Pump formula in a larger 60-serving tub at $59.99 — that's $1.00/serving, the best price-per-serving in our lineup. Stack a free shipping order ($125+ qualifies) and you've got 2 months of daily pre-workout for under $60.
Best for: Heavy users, anyone optimizing supplement spend. Buy: Mammoth Pump 60 servings.
4. Mammoth Swell — Cellular Volume + Hydration Angle
Mammoth Swell takes a different approach to the pump — instead of just blood-flow vasodilators, it stacks glycerol monostearate, taurine, and electrolytes for cellular hydration. Result: that "fuller" feeling that lasts the entire workout. $54.99 for 380g.
Best for: Lifters chasing the cellular swell sensation, hot-weather training, anyone who's a "responder" to glycerol-based formulas. Buy: Mammoth Swell Caffeine-Free Pre-Workout.
How to Choose Your Stim-Free Pre-Workout
- If you're a serious lifter chasing maximum pump: PEScience High Volume — the 8g citrulline dose is unmatched in the category.
- If you're price-conscious and train daily: Mammoth Pump 60 servings — best $/serving in the lineup.

Frequently Asked Questions
What's the best stim-free pre-workout in Canada?
PEScience High Volume is widely considered the best stim-free pre-workout for pure pump performance. It uses 8g of citrulline, agmatine, taurine, and glycerol monostearate — no caffeine, no stimulants. Top Nutrition & Fitness ships PEScience High Volume to all of Canada with same-day shipping, free shipping over $125, and 5% cashback rewards.
Can I take a stim-free pre-workout in the evening?
Yes — that's exactly what stim-free pre-workouts are designed for. Without caffeine or other stimulants, they don't disrupt sleep even when taken 1-2 hours before a 7-9 PM training session. PEScience High Volume, Mammoth Pump, and Mammoth Swell are all caffeine-free and safe for evening use.
Mammoth Pump vs Mammoth Swell — what's the difference?
Both are caffeine-free pump products from Mammoth. Mammoth Pump focuses on muscle pump and vascularity through citrulline and other vasodilators. Mammoth Swell adds a cellular hydration angle (glycerol, taurine) for fuller, more pronounced muscle volume. We carry both at Top Nutrition & Fitness — Mammoth Pump at $39.99 (30 svgs) or $59.99 (60 svgs), Mammoth Swell at $54.99.
Do stim-free pre-workouts actually work?
Yes, but they work differently than stim-based ones. Caffeine pre-workouts give you energy and focus; stim-free pre-workouts give you better blood flow, muscle pumps, and endurance through ingredients like citrulline malate, agmatine, glycerol, and taurine. Many lifters stack both — caffeine in coffee, stim-free pre-workout for the pump.
Are stim-free pre-workouts safe for women?
Yes — many women specifically prefer stim-free pre-workouts because they avoid caffeine sensitivity, anxiety spikes, and sleep disruption issues. There's nothing gender-specific about caffeine-free formulations; they're just gentler stimulant-wise.
Where can I buy stim-free pre-workouts in Canada?
Top Nutrition & Fitness ships stim-free pre-workouts including PEScience High Volume, Mammoth Pump (30/60 servings), and Mammoth Swell to all of Canada and the USA. Free shipping over $125, 5% cashback on every order, same-day shipping when ordered before 1 PM ET.
Can I stack a stim-free pre with creatine?
Absolutely — that's a popular combination. Stim-free pre-workouts and creatine work synergistically: the pre handles your pump and endurance, creatine handles your strength and recovery. They don't compete for absorption.
