How online clinic Mounjaro prices are structured — and what they should include

Step 1: understand what a legal Mounjaro price must cover

Mounjaro (tirzepatide) is a Prescription-Only Medicine under UK law. That means no clinic, pharmacy or website can lawfully supply it without a clinician's assessment first. So when you see a monthly figure on a provider's page, that figure should, at minimum, include the clinical consultation and the prescription itself, not just the pen.

In practice, many headline prices don't. Consultation fees of £20–£50, separate prescription charges, delivery fees and follow-up costs can all sit outside the number shown at the top of the page. A quick way to check: before you enter any payment details, look for a checkout summary that lists every line item. If the total jumps between the product page and the cart, something was hidden. That one check takes under a minute and tells you most of what you need to know about how transparent a provider is.

The NHS tirzepatide medicines page is a useful independent reference for what tirzepatide is and how it works, separate from any commercial pricing.

Step 2: factor in dose, because it changes the number significantly

Tirzepatide treatment starts at 2.5mg (a dose designed to let your system adjust, not to deliver the full therapeutic effect) and is typically titrated upward over several months toward 5mg, 7.5mg, 10mg, 12.5mg or 15mg, as a prescriber judges appropriate. Each pen covers four weeks. The cost per pen rises with the dose, so a patient on 5mg is paying considerably less per month than someone on 15mg.

This matters for price comparisons: a low headline figure often reflects the starter dose only. If you want to understand the realistic cost of a full treatment course, our Mounjaro price page walks through how the dose ladder affects what you'd actually spend. Separately, if you're looking at a specific point in your titration, there are detailed cost breakdowns for individual doses such as the 5mg pen, the 10mg pen, and if you want to see how costs stack up at the mid-range step, our page covering where to buy the 7.5mg pen at the most competitive UK price breaks that down in detail.

Step 3: read the aftercare terms before you commit

The pen is only part of the service. Mounjaro is titrated over months, which means you'll need clinical re-review each time your dose changes. Some providers charge for that separately; others lock you into a subscription that auto-renews whether you want the next pen or not.

At nume, there are no subscriptions and no auto-renewals. Every repeat order is reviewed by a prescriber before it ships. The price you see on our treatment page covers consultation, prescription, the medicine and next-working-day delivery, nothing charged separately afterward. We're not the cheapest provider in the market, and that's deliberate: the margin funds the clinical infrastructure that makes the service safe. You can read more about how we work on our about us page, and our clinical lead's background is outlined on the clinical team page.

If you have questions before starting, our FAQs cover the most common ones, and our team is reachable via contact seven days a week.

Why 'cheapest' is the wrong test for a prescription medicine

A small saving on a pen is not worth much if the supply chain isn't verified. The MHRA has warned publicly about counterfeit tirzepatide pens circulating online, fake pens have contained the wrong substances entirely, and in October 2025 an illicit manufacturing site producing counterfeit tirzepatide was raided in the UK. Sellers offering these medicines without a prescription, via social media or at prices noticeably below the market range, are the clearest red flags.

The right question isn't which clinic is cheapest, it's which clinic you can verify. Every legitimate UK online pharmacy is listed on the GPhC register; you can check any pharmacy at the GPhC register entry for nume's pharmacy in seconds. NICE's appraisal of tirzepatide, TA1026, sets out what clinically appropriate prescribing looks like, that's the standard a good provider holds itself to, regardless of price. For a broader look at what separates a credible online clinic from a risky one, our page on cheap Mounjaro online covers the warning signs plainly, and if you want a straightforward comparison of the most competitive Mounjaro prices available from legitimate UK providers, that guide pulls the key information together in one place.
