Caffeine-Free Pre-Workout

Pre-workouts made without caffeine or other stimulants, often called stim-free or non-stim. They suit evening training, anyone sensitive to caffeine, and people who already get enough caffeine from coffee and want a pre-workout that won't add more. Every product here states caffeine-free, stim-free, non-stim or zero stimulant in its name.

Without caffeine, these formulas usually focus on ingredients such as citrulline (often as citrulline malate), arginine, beta-alanine, betaine and glycerol, which many people use for the "pump" feel during training. Beta-alanine commonly causes a tingling sensation on the skin. The range includes Applied Nutrition Pump 3G Zero and ABE Stim Free Pump Shots, Bulk Dope Caffeine Free, Animal Pump Non Stim, NXT TNT Nuclear Pump, Kaged Pre-Kaged Stim-Free, Raw Nutrition Pump Non-Stim and Axe & Sledge Hydraulic. Compare the amount of each ingredient per serving, not just the ingredient list. Read our caffeine-free pre-workout guide for more.

How to compare stim-free pre-workouts

  • Citrulline: check the dose per serving and whether it is L-citrulline or citrulline malate.
  • Beta-alanine: check the amount, and expect some tingling.
  • Servings: some formulas use a double scoop; compare cost per full serving.
  • Label check: ingredients can change between batches, so always read the current label.

FAQs

Does caffeine-free pre-workout work?

Caffeine-free pre-workouts will not give the stimulant lift that caffeine does. They are built around ingredients such as citrulline and beta-alanine, and many people use them for training later in the day without caffeine.

What is in a stim-free pre-workout?

Common ingredients are citrulline or citrulline malate, arginine, beta-alanine, betaine, glycerol, taurine and electrolytes. Each product's label lists the exact amounts.

Is stim-free the same as caffeine-free?

Stim-free products leave out caffeine and other stimulants. Every product in this range states caffeine-free, stim-free, non-stim or zero stimulant in its name, but always check the label.

Can I take a stim-free pre-workout with coffee?

Yes, many people do. The caffeine then comes only from your coffee, so you control the amount.
