Mounjaro vs Zepbound

Mounjaro and Zepbound are the same molecule — tirzepatide. They are sold under separate FDA applications (NDA215866 and NDA217806), which is why they carry different approved indications, different labels and different supply records. On the regulatory record they are distinct products with an identical active ingredient.

Everything above is a field from Drugs@FDA, the FDA Drug Shortage Database, the EMA register or ClinicalTrials.gov. There is no efficacy comparison here and there will not be one: head-to-head claims belong to the trials that made them, and which drug suits a particular person is a question for a clinician.
