Which Bundle is Right for You?

New to Mounjaro? Start with our Intro Duo or Intro Trio bundles. These include the essential 2.5mg starting dose required for all new patients. Already established on treatment? Choose Progress bundles that match your current dose level.

All bundles require clinical assessment by our UK prescribers. Mounjaro is a prescription-only medicine that works alongside a reduced-calorie diet and increased physical activity. The medication activates GIP and GLP-1 hormones to help regulate appetite and promote feelings of fullness.

Complete your online consultation when ordering any bundle. Our GPhC-registered pharmacy team will assess your suitability for treatment. Standard approval takes 3 working days, or choose express processing for 24-hour approval.

First-time customers automatically receive £40 off with code FIRST40. Returning customers save £25 on every order. All bundles include discreet UK delivery and full prescriber support throughout your treatment.

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.
