Did Cellucor C4 Original change its formula?
THE SHORT ANSWER
Yes. Caffeine 150 to 200 mg, between the label states FormulaSignal observed on January 25, 2024 and February 26, 2024. It also moved beta-alanine 1.6 to 2 g. Those are observation dates; the exact day the brand changed it is not established.
CONFIRMEDReviewed July 29, 2026
The canonical DTC page transitioned from 150 mg caffeine to a fifth-generation formula with 200 mg caffeine, 2 g beta-alanine, Velox and PeptiPump. The page price shown alongside moved from $29.99 to $34.99 across the same two states.
FormulaSignal observed the earlier state on January 25, 2024 and the newer state on February 26, 2024. Those are observation dates, not the date the brand made the change.
CORRECTED · corr-unknown-basis-list-price-20260803
FormulaSignal corrected this Signal after publication. The finding stands with the corrected content below. Correction accepted August 3, 2026.
What we said: List price $29.99 to $34.99 on the homepage signal card, with observed standard price and price per serving increased 16.7% as commercial context
What the source showed: Both endpoint offer observations for 2024-01-25 and 2024-02-26 carry price_basis UNKNOWN. The record does not establish that either archived price was a list price rather than a promotional one, so neither the List price label nor a percentage move between them was supported.
What changed
The two labels, side by side.
Amounts as each label declares them. The percent is FormulaSignal's calculation.

DECLARED FACT COMPARISON
Caffeine: 150 mg to 200 mg (+33.3%).
DECLARED FACT COMPARISON
Beta-alanine: 1.6 g to 2 g (+25%).
OBSERVED PRICE, BASIS NOT COMPARABLE
Observed price: $29.99 observed January 25, 2024, $34.99 observed February 26, 2024.
Price basis recorded as UNKNOWN to UNKNOWN. The Record does not establish whether either figure was a list price, so no percentage is published from them.
OBSERVED PRICE, BASIS NOT COMPARABLE
Price per serving: $1.00 observed January 25, 2024, $1.17 observed February 26, 2024.
Price basis recorded as UNKNOWN to UNKNOWN. The Record does not establish whether either figure was a list price, so no percentage is published from them.
- Servings per container held at 30 across both states.
RECORDED COMMERCIAL CONTEXT
Caffeine increased 33.3% and beta-alanine increased 25%. The observed page price moved from $29.99 to $34.99 and price per serving from $1.00 to $1.17, but neither endpoint records a price basis, so this is a movement between two observed prices and not a measured list-price increase.

What this change does not tell you.
Limitations
- The evidence establishes an observation window, not an exact reformulation date.
- An observation date is the date FormulaSignal read a source. It is not a manufacture date and not the date a change was made.
- The window is based on nearest archived canonical states, not manufacture dates. Shopify metadata points to a likely February 20 DTC publication, and the legacy formula later coexisted on a hidden live page. Flavor is not resolved on either endpoint. Both are canonical DTC page states whose declared actives are presented product-wide rather than per flavor, so the comparison is like for like on actives and says nothing about flavor-specific excipients. Both offer observations carry price_basis UNKNOWN: an archived page shows the price displayed that day, and nothing on file establishes whether either figure was a list price or a promotion, so no percentage price change is published from them.
- A price in this Signal does not have list basis recorded on both endpoints, so it is reported as two observed prices and no percentage is derived from it.
- At least one endpoint did not record its claim set in full, so a claim present on one side and absent on the other is non-disclosure rather than removal.
- At least one endpoint did not record its certification set in full, so a certification present on one side and absent on the other is non-disclosure rather than removal.
