Is tirzepatide the same as Zepbound?

Yes: Zepbound is a brand name for tirzepatide, the same dual GIP and GLP-1 receptor agonist sold as Mounjaro for other labeled uses. This site's tirzepatide profile lists both names as aliases. Zepbound is the FDA approved brand for chronic weight management and for obstructive sleep apnea in people with obesity, based on SURMOUNT-1 (2,539 adults, up to 20.9% mean weight loss at 72 weeks on 15 milligrams versus 3.1% on placebo) and SURMOUNT-OSA (apnea-hypopnea index down by about 25 events per hour at 52 weeks). The molecule is the same; the labeled use and the pen you are handed are what differ.

Educational use only. This database summarizes published research and is not medical advice. Where a dose appears it is a record of what a trial or clinic ran, or what people describe doing, with its source attached. Nothing here is a recommendation for personal use.

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.
