How Weight Loss Injections Work

Mounjaro activates two natural hormones - GIP and GLP-1 receptors - which may help regulate appetite and promote feelings of fullness. This prescription-only medication can support weight management when combined with reduced-calorie eating and increased physical activity. Each single pen contains four weekly injections, administered subcutaneously using the simple pre-filled pen device.

How treatment works

How GLP-1 treatments help

Reduces appetite

Helps you feel fuller, sooner — so portions naturally shrink.

Curbs cravings

Quietens food noise so snacking and cravings ease off.

Slows digestion

Food stays in your stomach longer, steadying hunger between meals.

Steady blood sugar

Supports more stable glucose levels through the day.
