Whether you're starting treatment or maintaining your current dosage, buying individual pens allows you to control your supply without committing to larger quantities. Each pen contains four weekly injections of tirzepatide, a prescription-only medicine that may help support weight management when used alongside a reduced-calorie diet and increased physical activity.

How Mounjaro Works

Each pen contains tirzepatide, which activates GIP and GLP-1 - two natural hormones that regulate appetite. The treatment may help promote feelings of fullness and reduce food cravings, supporting your weight management goals when combined with lifestyle changes. Clinical studies demonstrate its effectiveness as part of a comprehensive weight management approach.
