How Mounjaro Works

Mounjaro mimics natural gut hormones (GLP-1/GIP) to:

1. Regulate appetite, reducing food cravings

2. Enhance satiety, promoting longer fullness between meals These dual actions create sustainable calorie reduction for significant weight loss. For optimal results, combine with a reduced-calorie diet.
