WHY A DATE MATTERS

Anyone can say 150 mg.
A record carries the date.

“How much caffeine is in Cellucor C4 Original?”

AN UNDATED ANSWER

150 mg

No date. No source. No way to know which formula.

THE DATED RECORD

200 mg

Per serving, on the label captured .

Open the source & history

Both numbers came from Cellucor’s own page. Only one tells you when.

An illustration, not a quote from any service. 150 mg was declared in the source captured Jan 25, 2024.

HOW THE RECORD HOLDS UP

Sources you can open.
Limits we say out loud.

EVIDENCE

Every finding names its source.

Reviewed by FormulaSignal and linked to a dated source; a changed webpage alone is only a lead.

FAILURES

Failed checks stay visible.

No confirmed change is not proof that nothing changed.

LIMITS

Nobody buys a verdict.

A label is what was declared, not what is in your tub or right for you. Brands cannot buy conclusions or placement.
