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 Aug 3, 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.

Which label?

Which label is a number from?

A caffeine figure without a date may describe a label that is no longer sold. These are the changes FormulaSignal has confirmed for this pair, and what each brand's shelf showed.

Bucked Up Pre-Workout: FormulaSignal could not read Bucked Up's product page at its last check. That is a fact about the page, not a finding that the product was discontinued.
