Comparison

Tirzepatide vs Mazdutide

GIP/GLP-1 versus glucagon/GLP-1: two dual-agonist strategies compared.

Tirzepatide

Established

Brand names: Mounjaro, Zepbound

Dual GIP/GLP-1 receptor agonist producing greater average weight loss than semaglutide in head-to-head trials.

Full Tirzepatide profile

Mazdutide

Clinical

Dual GLP-1 / glucagon receptor agonist showing strong weight loss and metabolic effects in late-stage trials, particularly in Asian populations.

Full Mazdutide profile

Attribute	Tirzepatide	Mazdutide
Category	Incretin / GLP-1 Compounds	Incretin / GLP-1 Compounds
Evidence tier	Established	Clinical
FDA status	FDA-approved (T2D and chronic weight management).	Not FDA-approved. Approved in China (2025).
Mechanism	Tirzepatide activates both GIP and GLP-1 receptors. The GIP component appears to modulate adipose tissue and improve insulin sensitivity, while GLP-1 action drives appetite suppression and glycemic control. Half-life ~5 days enables weekly dosing.	Mazdutide activates both GLP-1 and glucagon receptors. The glucagon arm is hypothesized to increase energy expenditure and improve hepatic lipid handling, while GLP-1 drives appetite suppression and glycemic control.
Key benefits	Up to 22.5% body weight reduction at 15 mg (SURMOUNT-1) Superior HbA1c lowering vs. semaglutide (SURPASS-2) Improvements in sleep apnea severity (SURMOUNT-OSA) Favorable lipid profile changes	Substantial weight loss in Phase III (GLORY-1) Improvements in hepatic fat and liver enzymes Glycemic improvements in T2D
Dosage range	2.5 – 15 mg weekly	3 – 9 mg weekly
Frequency	Weekly	Weekly
Route	SubQ	SubQ
Common side effects	Nausea, diarrhea, constipation, Injection site reactions, Hypoglycemia when combined with insulin or sulfonylureas	Nausea, GI effects typical of incretin class
