— What to expect
A typical course of Tirzepatide.
— The science
How Tirzepatide works, and what the research shows.
— How it works
Tirzepatide is a dual GIP/GLP-1 receptor agonist — it activates both incretin pathways instead of just one.
This dual action produces superior weight loss results vs semaglutide alone.
Phase 3 trials showed up to 22.5% body weight loss.
— Clinical evidence
The SURMOUNT-1 trial randomized 2,539 adults with obesity to tirzepatide 5/10/15 mg vs placebo.
Jastreboff et al., NEJM 2022At 72 weeks, mean weight reductions were 15.0%, 19.5%, and 20.9% on the active arms vs 3.1% on placebo — the highest weight-loss outcomes recorded for a pharmacological intervention at the time.
SURMOUNT-2 confirmed efficacy in patients with type 2 diabetes, and the SURPASS program demonstrated superior HbA1c reduction vs semaglutide head-to-head.
Frias et al., 2021Tirzepatide's dual GIP+GLP-1 mechanism appears to drive both stronger appetite suppression and improved metabolic flexibility.
