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 Original
200 mg against 350 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 Original
$1.17 against $2.50 a serving at the prices FormulaSignal observed (Oct 27, 2026 and Jul 25, 2026). Not every price here is established as a list price.
You want creatine in the same scoop: Cellucor C4 Original
Cellucor C4 Original declares Creatine Nitrate (as NO3-T) at 1 g; Legion Athletics Pulse's complete label declares no creatine.
You want more of the main actives at researched doses: Legion Athletics Pulse
2 of 3 main actives on Legion Athletics Pulse sit inside the dose range the cited research used, against 1 of 5 on Cellucor C4 Original. A comparison of numbers, not of how well either works.

Method
How this page was made.
What FormulaSignal did
- Read Legion Athletics Pulse's label as Legion Athletics published it, observed August 3, 2026.
- Read Cellucor C4 Original's label as Cellucor published it, observed October 20, 2026.
- Matched 10 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 3 on Legion Athletics Pulse; 1 of 5 on Cellucor C4 Original.
- Looked for confirmed formula changes on either product: 2 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.
