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.
What is not counted
Not counted: 169 pre-workouts in the Record whose label has not been normalized yet; 17 adjacent amino, EAA and thermogenic products, which are ranked on their own names and never as pre-workouts; 890 products in other categories. A product missing from this list may still qualify once its label is read.
Method
How this page was made.
What FormulaSignal did
- Counted every one of the 173 normalized pre-workouts and tested each against one rule: the label declares caffeine and the Record holds its total. Products declaring no stimulant are on the stim-free list instead.
- Ordered the 15 that qualify by the rule printed above, the same rule for every product.
- Took every figure from each product's dated Record; the labels read here were observed between August 2, 2026 and October 24, 2026. Each Record links the source for every figure.
What it did not do
- No taste test and no lab test. Every figure is what a label or a brand's own page declares, not what was measured in a tub.
- No score and no winner. Differences are measured and shown; nothing is rated.
- No payment and no preview. No brand paid to appear, and none saw this page before it was published.
- No health advice. Whether an ingredient or an amount suits you is a question for a clinician.
Questions
Common questions
Which pre-workout has the least caffeine?
15 pre-workouts meet this list's rule, out of 173 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. The full list is above, with a link to each product's dated Record.
How is this list ranked?
Ranked by declared caffeine per serving, lowest first, then by lower cost per serving. Only the lowest fifteen are shown.
Why isn't my pre-workout on this list?
Either its label does not meet the rule, or the Record has not read it completely yet. This list excludes 169 pre-workouts in the Record whose label has not been normalized yet; 17 adjacent amino, EAA and thermogenic products, which are ranked on their own names and never as pre-workouts; 890 products in other categories. You can request any product free from your Locker.
Does any brand pay to be ranked?
No. FormulaSignal takes no payment for a conclusion, a ranking or a placement. Product pages link to the product's Amazon listing, where FormulaSignal earns from qualifying purchases, but this list carries no such link and nothing that ranks it can read one: the order comes from the rule above and the labels on file.
