Is tirzepatide the same as Mounjaro?
Yes. Mounjaro is a brand name for tirzepatide. This site's profile lists Mounjaro and Zepbound as other names for the same molecule. Mounjaro is the FDA approved brand for type 2 diabetes and, from August 2026, for cutting major heart events in adults with type 2 diabetes. That is based on SURPASS-CVOT (13,299 people; major heart events in 12.2% on tirzepatide versus 13.1% on dulaglutide) and SURPASS-2 (1,879 people over 40 weeks, against semaglutide 1 milligram). Zepbound is the same molecule under a different brand, for weight and sleep apnea. A research-chemical vial labeled tirzepatide is not either approved product.

Part of names, absences, and legal limits. Brand versus molecule, side effects this site's citations did not measure, how long the trials actually ran, what national legal-status fields can say, and why two-compound answers do not scale to a larger stack.
