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: Bucked Up 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: Bucked Up Pre-Workout
$1.43 against $2.00 a serving at the prices FormulaSignal observed (Jul 23, 2026 and Oct 20, 2026). Not every price here is established as a list price.
You want creatine in the same scoop: Cellucor C4 Ultimate
Cellucor C4 Ultimate declares Creatine Nitrate (as NO3-T) at 1.5 g; Bucked Up Pre-Workout's complete label declares no creatine.

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.

Method
How this page was made.
What FormulaSignal did
- Read Cellucor C4 Ultimate's label as Cellucor published it, observed July 26, 2026.
- Read Bucked Up Pre-Workout's label as Bucked Up published it, observed August 18, 2026.
- Matched 17 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: 4 of 6 on Cellucor C4 Ultimate; 2 of 3 on Bucked Up Pre-Workout.
- Looked for confirmed formula changes on either product: 0 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.
