Stim vs Non-Stim Pre-Workout: Which Should You Choose?

Quick answer

Choose a stim pre-workout if you train earlier in the day and tolerate caffeine well. Choose a non-stim pre-workout if you train in the evening, are sensitive to caffeine or already drink a lot of coffee.

What is a stim pre-workout?

A stim pre-workout contains caffeine, sometimes with other stimulants. Check the caffeine per serving on the label and start with half a scoop if you are new to it.

What is a non-stim pre-workout?

Non-stim formulas leave out caffeine and usually focus on pump ingredients such as citrulline. They will not keep you awake after a late session.

Can I use both?

Yes. Plenty of our customers keep a stim tub for morning sessions and a non-stim tub for evening sessions.

How long before training should I take pre-workout?

20 to 30 minutes before you start.

Who should avoid stim pre-workouts?

Anyone under 18, pregnant or breastfeeding, or sensitive to caffeine.
