Question 1

What is a stim-free pre-workout?

Accepted Answer

A pre-workout without caffeine or other stimulants. You still get pump and focus ingredients like citrulline, beta-alanine and tyrosine, just without the wired feeling.

Question 2

Why choose stim-free?

Accepted Answer

If you train in the evening and want to sleep normally. Or if you already drink a lot of coffee and don't want to stack more caffeine. Also good if your heart or blood pressure is sensitive to stimulants.

Question 3

What ingredients should you look for?

Accepted Answer

Look for at least 6g citrulline (that's the clinical dose for pump). Beta-alanine works from 3.2g. Many stim-free products underdose these ingredients, so compare carefully.

Question 4

Can you train just as hard without caffeine?

Accepted Answer

For strength and endurance, yes. But you miss the mental kick from caffeine. Pump and blood flow are the same. Some people actually perform better because they're calmer and more focused.
