Clinical trials show tirzepatide produces greater average weight loss than semaglutide at comparable doses
Meaning it inhibits bacterial growth but does not sterilize

However, with the progression of research, it has become evident that GLP-1R is broadly distributed across various organs and tissues, including but not limited to the brain, heart, kidneys, intestines, eyes, and the vascular system (Meier, 2012
The FDA approved it in June 2021 specifically for chronic weight management making it one of the first GLP-1 receptor agonists with an explicit obesity indication rather than just a diabetes label
It is a unimolecular formulation based on the GIP structure, with structural modifications to the peptide chain that enable interaction with both GLP-1 and GIP receptors.39 Its biological action on the GIP receptor is five times greater than that on the GLP-1 receptor.39 Effects on weight loss, body composition and diabetes prevention The SURMOUNT programme shows that TZP reduces weight in a dose-dependent manner, achieving a 22.5% weight reduction at the maximum weekly dose of 15 mg40 (Table 1)
