Same word on a label does not mean same product.

Misleading
The circulating claim

“Peptide vendors sell the same tirzepatide as Zepbound.”

What the source record says

Sharing an ingredient name does not make an online product the FDA-approved drug. FDA warning letters have targeted tirzepatide sold as a research peptide without the approved product's verified manufacturing and labeling framework.

Why the claim misleads

An ingredient name is being used as proof of product equivalence.

Correction

Same word on a label does not mean same product.

What changed

Added the source-verified Claim Check to the structured claim/source/change registry.

What would change our answer

A well-controlled human study tied to the exact product, population, route, and claimed outcome could change the answer. Mechanism, anecdotes, or a different product cannot substitute for that evidence.
