Which fits you
Choose by what you care about.
Each line is a measured difference between the two labels, not a verdict. Nothing here says either product works, or is safe for you.
You want less caffeine per serving: Cellucor C4 Sport Pre-Workout
200 mg against 300 mg declared per serving. Less is not safer and more is not better; how much suits you is a question for a clinician.
Cost per serving matters most: Cellucor C4 Sport Pre-Workout
$1.10 against $2.00 a serving at the prices FormulaSignal observed (Oct 20, 2026). Not every price here is established as a list price.
You want more of the main actives at researched doses: Cellucor C4 Ultimate
4 of 6 main actives on Cellucor C4 Ultimate sit inside the dose range the cited research used, against 2 of 5 on Cellucor C4 Sport Pre-Workout. A comparison of numbers, not of how well either works.

Method
How this page was made.
What FormulaSignal did
- Read Cellucor C4 Sport Pre-Workout's label as Cellucor published it, observed October 16, 2026.
- Read Cellucor C4 Ultimate's label as Cellucor published it, observed July 26, 2026.
- Matched 12 declared active ingredients by normalized identity, so two brand names for one compound line up.
- Checked each main active's declared dose against the range the cited research used: 2 of 5 on Cellucor C4 Sport Pre-Workout; 4 of 6 on Cellucor C4 Ultimate.
- Looked for confirmed formula changes on either product: 1 on file, each reviewed against two dated sources.
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.
