Are pump supplements stimulant-free?

Not all of them. HD Muscle PumpHD Stim Free, Ghost Pump Non-Stim and Believe Pump Addict Stim-Free list no caffeine, but Believe Pump Addict MAX 2.0 lists 175 mg per half scoop and Mammoth Pump 200 mg per scoop. Check the panel before you buy.

How much citrulline is in a serving?

HD Muscle PumpHD lists 5.5 g L-citrulline per half scoop, Ghost Pump 3,000 mg per scoop and Believe Pump Addict Stim-Free 6,000 mg citrulline malate. Citrulline malate includes malic acid: Believe's MAX label shows 4,080 mg providing 2,285 mg L-citrulline.

What is glycerol in a pump formula?

Glycerol is another common pump ingredient. RAW Pump2's supplement facts list one ingredient, 6 g of Glycersize (65% glycerol powder) per scoop, while Believe Pump Addict Stim-Free includes 1,000 mg glycerol monostearate alongside citrulline and agmatine.

Can I take a pump product with my pre-workout?

A stimulant-free pump is often paired with a caffeinated pre-workout. Check both panels first: Applied Nutrition ABE Pump and HD Muscle PumpHD also contain creatine and beta-alanine, so those amounts add to what's in your pre-workout.

Do pump supplements contain allergens?

Some do. HD Muscle PumpHD lists casein hydrolysate from milk, and RAW Pump2 is made on shared equipment that also processes milk, soy, egg, wheat and other allergens. Read the label if you avoid dairy or other allergens.

Does Fuel Supplements ship pump supplements across Canada?

Product Description

HD Muscle Pump HD Stim Free Pre Workout is a stimulant-free pump formula built around L-Citrulline, Beta-Alanine, Creatine Monohydrate, Betaine, and Nitrosigine, with Alpha GPC, Choline, and L-Tyrosine rounding out the label. Available in 20 and 40 serving sizes, it's suited to lifters who want blood-flow and workout-feel support without caffeine. Buy it online at fuelsupplements.com with fast Canada-wide shipping.

Cost per serving: $2.00 (40 servings at $79.99) · serving size 1/2 scoop (17.25 g)

Key Benefits

L-Citrulline and Nitrosigine (arginine silicate inositol) for blood flow and muscle pump support
Beta-Alanine included at a measured dose per serving
Creatine Monohydrate and Betaine Anhydrous for training performance
Alpha GPC and Choline Bitartrate plus L-Tyrosine for focus during training
Zero added stimulants — no caffeine on the label
Available in 20 or 40 serving formats with a 1/2 scoop or full scoop serving option

When to Use It

This is a fit for lifters training in the evening, or anyone who wants pump and focus support without a stimulant crash afterward. Because it's stim-free, it pairs well with a separate caffeine source on days you want more of a kick, or stands alone on days you don't. Beta-Alanine and Creatine are also present, so some users treat it as a daily training-day formula rather than an occasional-use pre-workout.

Directions and Suggested Use

Suggested Use

Mix 1/2 scoop or 1 scoop with water, according to your chosen serving size and personal tolerance, and consume before training. Always follow label directions.

Payment Methods

Your payment information is processed securely. We do not store credit card details nor have access to your credit card information.

Why these go together

Stimulant pre-workouts raise sweat rate — electrolytes protect hydration and pumps, while creatine compounds the strength work you're showing up to do.
