Which pre-workouts changed their formula?
THE SHORT ANSWER
15 of the 147 pre-workouts FormulaSignal has verified to the label have a confirmed formula change or two labels published at once: Cellucor C4 Original, GHOST Legend, Gorilla Mind Gorilla Mode, Legion Athletics Pulse, REDCON1 Total War, RSP Nutrition AminoLean Energy / Pre Workout, RYSE Loaded Pre, Cellucor C4 Sport Pre-Workout, NutraBio Base Pre-Workout, ProSupps Mr. Hyde Max Pump, ProSupps Mr. Hyde Xtreme, Jacked Factory Altius Clinically Dosed Pre-Workout, Axe & Sledge DBAP, Huge Supplements Pump Serum and Huge Supplements Wrecked Enraged. The other 132 have no confirmed change on file. For 147 of the 147, archives have not yet been fully searched for earlier labels, so "no change on file" is not proof nothing changed.
Each change is between two dated labels of the same product, compared like for like.

Method
How this page was made.
What FormulaSignal did
- Answered from the 515 records that are Signal Verified today: labels read twice, dated and sourced.
- Counted a change only between two dated labels of the same product, flavor, size and sales channel.
- Computed every figure on this page from those records when the page was served, so it moves when the Record does.
What it did not do
- No look inside a tub. A label says what a product declares. A record does not establish what a particular container holds.
- 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.

Did C4 change its formula?
Yes. Caffeine went from 150 mg to 200 mg. Beta-Alanine went from 1.6 g to 2 g. Between labels seen Jan 25, 2024 and Feb 26, 2024, compared like for like. Two labels are still published. Both seen Oct 20, 2026. One declares 200 mg caffeine and 2 g beta-alanine. The other declares 150 mg caffeine and 1.6 g beta-alanine.
Why do pre-workouts change formulas?
A label does not give a reason. FormulaSignal records what changed and when each label was seen, not why.
