How much are Mounjaro shots in the UK — and what does the price actually cover?

Step 1: understand what the quoted price usually refers to

Most private providers quote a monthly price that corresponds to a single KwikPen, which contains four weekly doses at one specific strength. Mounjaro is available in six strengths (2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg and 15 mg) and prices rise at each tier because the pen itself costs more. Treatment begins at 2.5 mg to let your system adjust, then a prescriber titrates the dose upward at roughly four-week intervals based on how you're responding. So the price you see advertised for a starter pen and the price you'll pay at a therapeutic dose can look quite different from each other, and if you want a full breakdown of what drives that difference, our page on how much Mounjaro jabs cost walks through the tier-by-tier picture in detail. For a deeper look at how the per-pen cost breaks down at a particular strength, the 5 mg pricing page gives a useful concrete example of how dose-level affects what you pay.

A quick check worth doing: look at the provider's pricing page and count how many separate line items appear before you reach a final total. Some services list the pen price alone, then add consultation, prescription and delivery as extras. Others (like the treatment options at nume) fold everything into one number. Neither approach is inherently wrong, but mixing up the two types makes comparisons meaningless.

Step 2: list what is and isn't included in the price you're looking at

Headline prices for Mounjaro shots frequently exclude some or all of the following: an initial consultation fee (which can run to £30–£50 or more separately), a prescription charge on top of the medicine cost, delivery (especially if you want tracked or next-day), and any ongoing aftercare or dose-review appointments. If you're trying to work out what a single administration is likely to set you back once those extras are accounted for, our dedicated page on how much the Mounjaro shot costs unpacks the components that typically make up that final figure. A service that charges £149 all-in for a starter pen is structured very differently from one charging £130 for the pen alone before three further fees stack on top.

Clinical oversight has real value that doesn't always show in a price comparison. Mounjaro is a Black Triangle medicine under additional MHRA monitoring, and the prescriber reviewing your case before each repeat order is not an optional extra, it is a legal and clinical safeguard. NICE's appraisal of tirzepatide, TA1026, is built on the assumption that treatment happens within a structure that includes ongoing clinical oversight and lifestyle support. Services that don't provide that are not offering the same thing, even if the pen is the same.

Step 3: place nume's pricing in context, and understand why we're not the cheapest

At nume, one price covers the full picture: consultation, prescription, the treatment itself, free next-working-day DPD delivery, and seven-day aftercare with clinical re-review before every repeat. There is no subscription. Every order is assessed fresh. We are not the cheapest option available. That is a deliberate position, not an oversight. Running a GPhC-registered pharmacy with a clinical team that reads every single consultation personally costs more than a model that automates the assessment or skips the aftercare. Our about us page sets out who we are and how we work; the clinical team page shows who is reading your notes. You can verify our pharmacy on the GPhC register directly at registration number 9012878. Current treatment prices are shown on the consultation and treatment page, we don't list per-pen prices in body copy because the right price for you depends on the dose your prescriber determines is appropriate.

Step 4: why cheapest is the wrong question for a prescription medicine

The MHRA has documented the seizure of roughly 20 million doses of illegally traded weight-loss medicines (worth around £45 million) including the first UK raid on a site manufacturing counterfeit tirzepatide pens, in Northampton in October 2025. Fake pens have in some cases contained insulin rather than the stated medicine, with serious consequences for patients. The MHRA advises verifying any online pharmacy against the GPhC register before buying, and warns that sellers offering these medicines without a prescription or at prices far below the market rate are significant red flags. Discount codes from unknown sources for prescription-only medicines are another warning sign worth taking seriously.

For a POM like Mounjaro, the question that actually protects you is not "who is cheapest?" but "is this pharmacy registered, is this medicine coming through the licensed UK supply chain, and is a real clinician assessing me?" Those things have a floor price, and providers below it are cutting something that matters. If you have questions about how our process works or what happens at each step, the FAQs page covers the most common ones, and the contact page connects you directly with our team.
