THE SHORT ANSWER
15 pre-workouts meet this list's rule, out of 76 normalized pre-workouts in the FormulaSignal Record. Six Star Pro Nutrition Pre-Workout Explosion 2.0 declares the least caffeine of the pre-workouts that declare any: 160 mg per serving.
Read from the labels on file, the newest observed August 18, 2026. No brand pays to appear, and the order comes from the rule printed below.
The rule
What qualifies, and how it is ordered.
Qualifies: The label declares caffeine and the Record holds its total. Products declaring no stimulant are on the stim-free list instead.
Order: Ranked by declared caffeine per serving, lowest first, then by lower cost per serving. Only the lowest fifteen are shown.
Note: A half serving is not a lower-caffeine product and the Record does not treat it as one. Serving advice is a question for a clinician.
