What is Tirzepatide?
Tirzepatide is a synthetic peptide that simultaneously activates two incretin receptors — GLP-1 and GIP. This dual-agonist mechanism produces stronger effects on glucose control and body-weight than single-receptor GLP-1 agonists like semaglutide.
It is dosed once-weekly and titrated over months. The SURMOUNT trials reported ~22.5% mean body-weight reduction at the 15 mg dose, currently the leading approved weight-management agent by efficacy.
