Tirzepatide
Tirzepatide is Eli Lilly’s dual GLP-1 and GIP receptor agonist. Marketed as Mounjaro for T2D and Zepbound for weight loss (plus obstructive sleep apnea since 2024), it consistently outperforms semaglutide in head-to-head trials. We cover why dual-agonist works better, the SURMOUNT and SURPASS trial data, and which patients see the strongest results.
