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 (Aug 3, 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.

What both declare, and what only one does.

Matched by FormulaSignal's normalized identity, so two brand names for the same compound line up and two forms of one ingredient do not. Vitamins, minerals and electrolytes are left out; caffeine is compared as a total above.
