GLP-1/Glucagon

Mazdutide

Also known as IBI362, LY3305677

Mazdutide is an experimental weekly injection that activates two hormones (GLP-1 and glucagon) to drive weight loss and improve blood sugar — glucagon adds an extra fat-burning angle.

Typical dose

Investigational GLP-1 / glucagon receptor dual agonist (an oxyntomodulin analog) for obesity and diabetes. Once weekly.

Mechanism of action

Oxyntomodulin-based dual agonist pairing GLP-1 incretin effects with glucagon-mediated energy expenditure.

Investigational — not FDA approved. Half-life is poorly constrained in public data (reported ~7–45 days); treat the model as approximate.
