Mounjaro for £99 a Month: What Private Treatment Actually Costs in the UK

Is there a legitimate Mounjaro prescription for £99 a month in the UK?

It's a question our prescribers hear most weeks, and the honest answer is: not through a properly regulated pathway. Mounjaro (tirzepatide) is a Prescription-Only Medicine under the Human Medicines Regulations 2012. That means every supply requires a valid prescription issued after genuine clinical assessment, there is no lawful shortcut around that step.

The UK list price of Mounjaro alone (before any pharmacy margin, consultation fee or delivery cost) already exceeds £99 at all but the starting dose, and it rose sharply in September 2025. The highest-dose pen now carries a list price of around £330 per four-week supply, as widely reported following Eli Lilly's UK pricing update. For context, if you want to understand what the Mounjaro price looks like across all available doses and strengths, typical figures range from around £149 at the lower end to around £375 at the upper. A price of £99 sits well below that range for every available strength.

That doesn't make every low headline price fraudulent, some providers separate their consultation, prescription and delivery charges so the medicine price appears low before extras are added. But some sellers operating outside the regulated UK supply chain have priced medicines at figures that have no legitimate explanation. The MHRA has seized millions of doses of illegally traded weight-loss medicines and raided an illicit manufacturing site producing counterfeit tirzepatide pens in 2025. If a price looks implausible, it should prompt a question, not a purchase.

What do the headline prices from legitimate providers usually leave out?

Even where a provider is regulated and genuine, a headline monthly price doesn't always tell the full story. How much Mounjaro costs per month for most patients includes several distinct components, and providers bundle these differently.

Consultation fees are the most common omission. Some clinics charge £30–£50 per consultation, billed separately at each dose review. Prescription fees may also sit outside the advertised price. Delivery (which for a temperature-sensitive injectable medicine requires tracked, refrigerated-compatible logistics) is sometimes charged per order. Aftercare, dose-increase reviews and clinical support between orders can be add-ons too.

When those elements are added back, the effective monthly cost often looks quite different from the figure in the headline. A genuinely all-inclusive price is worth identifying before you start treatment, because the costs of ongoing support (prescriber reviews at each titration step, clinical oversight if side effects arise) aren't optional extras in safe prescribing. They're the point.

You can see how providers compare on this by looking at what a transparent all-in monthly cost looks like and checking exactly which services are covered.

What does the price at a regulated service like nume actually include?

We don't try to win on price. That's a deliberate position. A named prescriber reads every consultation personally, the same day it's submitted, not a day or two later, not via an algorithm. ID is verified with photo documentation. Weight is confirmed on a live video call. Every repeat order receives a fresh clinical review before anything is dispatched. None of that is optional and none of it is charged separately.

One transparent price at nume covers the consultation, the prescription, genuine Mounjaro from the licensed UK supply chain, and free next-working-day tracked delivery by DPD in plain packaging. There is no subscription. Aftercare is available seven days a week. If you order before noon on a working day and your prescription is clinically approved, your treatment leaves our GPhC-registered pharmacy the same day.

You can verify our pharmacy directly on the GPhC register at pharmacyregulation.org, registration number 9012878, that's the check worth doing for any online pharmacy before you hand over personal details or payment. Breaking down the total cost of Mounjaro treatment shows why the components of that price matter as much as the total.

Why is 'cheapest' the wrong question to ask about a prescription medicine?

For most purchases, the lowest legitimate price is a reasonable target. Prescription medicines are different. Mounjaro is not a supplement or a wellness product, it is a regulated injectable that requires clinical screening to identify contraindications, a licensed supply chain to ensure authenticity, and ongoing prescriber oversight to titrate safely and monitor for adverse effects.

The NICE appraisal of tirzepatide (TA1026) and the NHS patient information for tirzepatide both make clear that this is a medicine used within a clinical framework, not a product you adjust independently based on how things feel. Prescribers are assessing you as an individual: your weight history, other medicines you take, any conditions that may affect suitability, and your progress at each dose.

A small saving that comes at the cost of that clinical infrastructure isn't a saving at all if the supply chain is unverified, if no one is reviewing your progress, or if the pen that arrives isn't what it claims to be. The right question isn't which provider charges least, it's which provider gives you a genuine prescription, a confirmed-authentic medicine, and someone to call if something doesn't feel right.
