Did Cellucor C4 Original change its formula?
THE SHORT ANSWER · CHANGED
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.

What the confirmed change shows
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.
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 Both offer observations carry price_basis UNKNOWN: an archived page shows the price displayed that day, and nothing on file establishes whether either figure was a list price or a promotion, so no percentage price change is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. Both endpoints are cellucor.com pages, so this change describes the brand's own store only. Retail and the legacy first-party page still sell a 150 mg caffeine label under their own GTINs (finding fnd-cellucor-c4-original-channel-split).
Tastes different?
Check your tub against this label. Line by line.
Turn your tub to the Supplement Facts panel. If an amount differs, you hold a different label from the one read here. If every line matches, the label does not explain the difference.

Method
How this page was made.
What FormulaSignal did
- Read the label Cellucor published for Icy Blue Razz, dated Oct 20, 2026, twice and independently: 60 of 60 fields agreed.
- Kept all 3 dated labels with the day each was seen and its source.
- Counted a change only between two dated labels of the same flavor, size and sales channel: 1 confirmed change on file.
- Printed every gap the Record knows about, above, instead of leaving it out.
What it did not do
- No look inside your tub. A product record does not establish what a particular container holds, and label dates are not manufacture dates.
- 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
Cellucor C4 Original: formula questions
Did Cellucor C4 Original 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.
My Cellucor C4 Original tastes or feels different. Is it a new formula or a bad batch?
A label can answer half of that: whether the formula on the label changed. Compare the Supplement Facts panel on your tub with the label dated Oct 20, 2026 on this page (it declares Vitamin B6 (as Pyridoxal-5-Phosphate) 3.4 mg, Folate (as 6S-5-Methyltetrahydrofolate calcium salt) 100 mcg DFE and Vitamin B12 (as Methylcobalamin) 6 mcg per serving). If your amounts differ, you hold a different label from the one on file. If they match, the label does not explain the difference. FormulaSignal does not test what is inside a tub.
How do I know if I have the old or new Cellucor C4 Original?
Read the Supplement Facts panel. The label seen Jan 25, 2024 declares 150 mg caffeine; the label seen Feb 26, 2024 declares 200 mg. The label seen Jan 25, 2024 declares 1.6 g beta-alanine; the label seen Feb 26, 2024 declares 2 g. The date on a tub is not a formula date, so go by the amounts printed.
Why can two Cellucor C4 Original labels both be published?
When observed on October 20, 2026, Cellucor published two C4 Original labels side by side. cellucor.com/products/c4-original showed the 5th Gen panel (200 mg caffeine, 2 g CarnoSyn beta-alanine). A second Cellucor listing, cellucor.com/products/c4-original-old, offered 30 and 60 servings "from 150mg of caffeine" under GTINs whose filed and retail-photographed panels declare 150 mg caffeine, 1.6 g CarnoSyn beta-alanine, 1 g creatine nitrate and 1 g citrulline malate.
What did FormulaSignal check, and what not yet?
Checked: the Icy Blue Razz label from Cellucor, dated Oct 20, 2026, read twice with 60 of 60 fields matching. Not yet: 2 of 3 flavors on the brand's store (2026-10-27) have no panel read yet; Earlier labels may exist that the Record has not recovered; a missing observation is not proof nothing changed.
Will I find out if Cellucor C4 Original changes its formula later?
Cellucor C4 Original is re-checked within 180 days, and it is on the monitoring schedule so the next label change is looked for. Save it to your Locker free to keep its dated label beside the one you take. A change counts only when two dated labels of the same flavor, size and sales channel differ.
