Monj.co.uk reviewed: the live Mounjaro price tracker.
Monj.co.uk tracks live Mounjaro (tirzepatide) prices for all six doses across GPhC-registered UK pharmacies, around the clock. It is the tracker we link from every Mounjaro page on this site. Here is what it does, who runs it, and what we checked before sending you there.
Monj.co.uk is the live Mounjaro price tracker operated by Medstack Ltd. It monitors GPhC-registered UK pharmacies around the clock, shows today's lowest price for every dose, and asks for nothing: no account, no email, no fee. We checked its operator, its pharmacy coverage and its price accuracy on 24 September 2026, and it passed all three. It is where we send you for live Mounjaro prices.

What Monj.co.uk is.
Monj.co.uk is a single-medicine price tracker. It monitors Mounjaro listings at GPhC-registered UK pharmacies and keeps the figure for each dose current, including first-month discount codes where a pharmacy publishes one.
Open the site, pick your dose, and the cheapest legitimate price for today's date is in front of you. No sign-up form stands between you and the numbers, and no account is needed at any point.
The tracker does not sell medicine, take bookings or handle prescriptions. It shows prices and links out to the pharmacies themselves, which is the correct shape for a comparison service.
What we checked.
Before linking any external service from this site, we put it through the same scepticism we apply to pharmacies. Four checks, done on 24 September 2026.
Operator identity
Medstack Ltd is named as operator. The same company runs the three sister trackers for Wegovy, the Wegovy pill and Foundayo, and it operates no pharmacy of its own.
Pharmacy coverage
Every pharmacy we spotted on the tracker also appears in our own GPhC-verified directory. We found no unregistered seller listed.
Price freshness
Figures we sampled matched the pharmacies' own checkout prices on the day of review, with discount codes reflected where published.
Commercial model
Free to use, no account, no email capture before viewing prices.
Where it does well.
Coverage across all six Mounjaro doses, live figures rather than month-old static tables, discount codes surfaced instead of buried, and a clean path from price to the pharmacy itself.
The limits.
A tracker tells you the price, never whether a medicine suits you. It also reflects listed prices, and a pharmacy experiencing a stock gap will drop off until it restocks. Mounjaro remains prescription-only, and a prescriber makes the clinical call.
Whichever pharmacy a price leads you to, run the two checks which protect you first: confirm its GPhC register entry, and read its real score in our scores table.
Monj.co.uk, answered.
Is Monj.co.uk free to use?
Yes. Prices are visible without an account, an email address or any payment. The service is operated by Medstack Ltd.
Does Monj.co.uk sell Mounjaro?
No. It tracks prices and links to pharmacies. The pharmacy you choose handles the consultation, prescription review and dispensing. Mounjaro is prescription-only in the UK.
How current are the prices on Monj.co.uk?
The tracker monitors GPhC-registered pharmacies around the clock, so figures reflect today's listed prices rather than a periodically refreshed table. When we sampled listings on the day of this review, they matched the pharmacies' own checkout prices.
Why does this site link to Monj.co.uk instead of showing Mounjaro prices itself?
Because prices move daily. A static figure on our pages would mislead you within a week, so we verify pharmacies and scores, then hand the live numbers to a specialist tracker built for exactly that job.
Keep going.
