How to compare Mounjaro prices in the UK: a buyer’s guide
A Mounjaro price comparison shows what each UK pharmacy charges for the same medicine at the same dose, including delivery and consultation fees, so you can see the real total rather than a headline figure. Prices for identical Mounjaro pens differ by well over £100 a month between GPhC-registered pharmacies, and the cheapest provider at your starting dose is often not the cheapest once you titrate up. Monj tracks those prices independently, takes no payment for ranking, and does not sell or dispense medicines. Last price update: August 21, 2026.

What actually changes the price you pay
Four things move the total, and only the first is usually advertised:
- The dose. Price rises as you titrate. A pharmacy that leads at 2.5mg can be mid-table at 10mg, so compare at the dose you expect to maintain on, not just the one you start on.
- First order versus repeat. Welcome discounts can hide a higher ongoing price. Treatment usually runs a year or more, so the repeat price is the number that matters.
- Consultation and delivery. Some pharmacies bundle both, others add them at checkout. Two identical headline prices can differ by £20 or more once these appear.
- Subscription terms. Recurring plans can be cheaper per month but harder to pause if you need a break or your dose changes.
Comparing safely, not just cheaply
Mounjaro is a prescription-only medicine, so every legitimate UK seller must be registered with the General Pharmaceutical Council and must assess you before supplying. A price far below the rest of the market is a warning sign rather than a bargain: unlicensed and counterfeit pens circulate, and the MHRA has repeatedly warned about them. Check the pharmacy’s GPhC number on the official register, expect a real consultation, and read our guides on spotting a fake pharmacy and how we verify every provider.
Common questions
How much does Mounjaro cost in the UK? Private prices vary widely by pharmacy and dose, and they move often, which is why we show live figures rather than fixed numbers. Use the live comparison table for current totals and the discount price list for prices with working codes applied.
Why is the same Mounjaro cheaper at one pharmacy than another? Pharmacies set their own margins, consultation fees and delivery charges, and negotiate different supply terms. The medicine is identical because it comes from the same manufacturer; what differs is the service wrapped around it.
Is the cheapest Mounjaro safe? Yes, provided it comes from a GPhC-registered pharmacy following a proper consultation. Cheap is not the same as unregulated. What is unsafe is buying without a prescription, from a seller you cannot verify, or from anywhere offering it without clinical assessment.
Can I get Mounjaro on the NHS? Access is limited and criteria are strict, with long waits in most areas. Read the full NHS guide before assuming private is your only route.
