Peptide Comparison
Semaglutide vs Tirzepatide
Wegovy and Zepbound are the weight-loss formulations of semaglutide and tirzepatide. Both are FDA-approved for chronic weight management; Zepbound's dual-agonist mechanism has produced greater average weight loss in pivotal trials.
Semaglutide
Semaglutide is a GLP-1 receptor agonist FDA-approved for type 2 diabetes (Ozempic) and chronic weight management (Wegovy). Clinical trials demonstrate significant reductions in body weight and cardiovascular risk markers. It works by enhancing insulin secretion, suppressing glucagon, and reducing appetite.
