Mounjaro®
Tirzepatide · GLP-1 / GIP Injection
Weekly weight-loss injection that targets two appetite-regulating hormones.
Mounjaro® (tirzepatide) is a once-weekly prescription injection that activates both GLP-1 and GIP receptors. In clinical studies, patients taking Mounjaro achieved some of the highest average weight reductions recorded for a weight-loss medicine. It works by slowing digestion, reducing hunger signals and improving how your body responds to food — helping you stick to a lower-calorie lifestyle with far less effort.
