Last checked 9 Oct 2026 at 7:09pm Prices update several times a day. Every pharmacy at your dose sits in the Mounjaro discount price list.

Job two: check the pharmacy before you pay

Every pharmacy on Monj holds a General Pharmaceutical Council registration. Monj checks certificates manually. Run the five checks yourself with the guide to checking a pharmacy is genuine. Published inspection outcomes sit in the pharmacy score records.

Job three: a tested discount code

Many pharmacies give money off a first order. Monj applies each tested offer inside the price list, so the total on screen matches the total at checkout. Each pharmacy has its own code page in the pharmacy directory.

Job four: switching and maintenance

Pharmacies set their own BMI rules inside the licence, so a low price is worth nothing from a pharmacy unable to prescribe for you. The BMI requirements guide lists every pharmacy. Moving provider? Read the switching guide. Staying on treatment at a lower weight? See the maintenance pharmacies.

Job five: straight answers
