Monj.co.uk reviewed: the live Mounjaro price tracker.
Monj.co.uk lists Mounjaro (tirzepatide) prices from 80 UK pharmacies, for all six doses. Every Mounjaro page on this site links to it, so we looked at who runs it, what it covers and where it falls short. We last revised this review on 13 October 2026.
Monj.co.uk is a free Mounjaro price tracker run by Medstack Ltd. On 13 October 2026 it listed 80 pharmacies for the 2.5mg starting dose. Medicspot and New Health were cheapest at £90.00 and the dearest listing was £229.00, a gap of £139 on the first month. You need no account to see the prices. Monj does not sell or prescribe anything. We send you there for the full Mounjaro price list.

What Monj.co.uk is.
Monj tracks one medicine. It lists what each pharmacy charges for Mounjaro at every dose, and a pharmacy's row is updated when its price changes.
There are two main lists. The discount price list shows what a new customer pays once the pharmacy's offer or code is applied. The standard price list shows the price with no discount. The second list matters from your second order onwards, when most new-customer offers have run out.
Monj says each figure is the full checkout total, with delivery and any pharmacy fees included.
Monj does not sell medicine, take bookings or handle prescriptions. Each row links to the pharmacy, or to Monj's own page about the pharmacy's offer. The pharmacy handles the consultation and the prescription.

What we checked.
We ask the same questions of a price tracker as we ask of a pharmacy. These four were last checked on 13 October 2026.
Who runs it
Medstack Ltd is named as the operator. The company is registered at Companies House under number 16439872. It also runs the trackers for Wegovy, the Wegovy pill and Foundayo, and it operates no pharmacy of its own.
Which pharmacies it lists
All 80 pharmacies on the list show a GPhC premises number. Most are in our directory already. A few newer names are not, so check those on the register yourself.
How fresh the prices are
Of the ten cheapest rows, four changed price in the week before this review, the latest on 12 October. The oldest of the ten was last changed on 5 September. An unchanged price is not always a stale one, but confirm the figure at checkout.
What it costs you
Nothing. The prices show without an account or an email address.
Where it does well.
It covers all six doses, so you can price the dose you expect to be on in three months as well as the one you start with.
It keeps discount prices and standard prices apart. A first-month offer does not hide what the pharmacy charges afterwards.
You can also filter the list, for example by delivery method or by whether a pharmacy accepts patients with a certain medical condition.
The limits.
A price list cannot tell you whether Mounjaro is right for you. A prescriber decides, and Mounjaro is prescription-only.
Prices are entered pharmacy by pharmacy, so a row can lag behind a change the pharmacy made the same morning. We have not placed test orders at all 80 pharmacies, and we cannot vouch for every figure.
New-customer prices last for the first order only. The cheapest first month is not always the cheapest pharmacy over six months, so look at the standard list too.
Whichever pharmacy you pick, check two things first: its GPhC register entry and its score in our scores table.
