Mounjaro 10mg in stock: how to access it safely and legally in the UK

Is Mounjaro 10mg available, and how do dose requests actually work?

Mounjaro comes in six UK strengths: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg. Treatment always begins at 2.5mg — the first pen's job is to let your body adjust, not to drive the bulk of your weight loss. Dose increases happen in roughly four-week steps, and a prescriber decides each one based on your response and tolerability.

So if you're searching for Mounjaro 10mg specifically, you're almost certainly already on treatment and looking to continue at that dose. A question our prescribers hear most weeks is whether a patient can order a higher dose directly if they feel ready for it. The honest answer: no. Each dose step requires a clinical review, and at nume that review happens before every repeat order. That's not a barrier placed in your way, it's what keeps treatment safe. You can see an overview of the full treatment pathway on our Mounjaro information page.

If you want to confirm whether the 10mg pen is currently available, you can check our dedicated page covering Mounjaro 10mg stock, which is updated as supply changes. The right place to confirm current stock is during your consultation, not on a product listing page. If a particular strength is unavailable, your prescriber will discuss the options with you directly.

What is the only legal route to a Mounjaro prescription in the UK?

Mounjaro (tirzepatide) is a Prescription-Only Medicine. Under the Human Medicines Regulations 2012, it cannot legally be supplied without a valid prescription issued after a clinical assessment. That applies to every dose, including 10mg.

The licensed private route runs like this: you complete a consultation, a GPhC-registered prescriber reviews it personally and decides suitability, a prescription is issued if appropriate, and your pharmacy dispenses and ships it. At nume, that whole sequence (from consultation submission to same-day dispatch) happens within a single working day when you order before 12pm. You can check current stock and start that process at our Mounjaro online ordering page, or explore how the wider process works through our guide to buying Mounjaro in the UK.

The NHS route exists too, but the eligibility criteria are strict and phased, and waiting lists are common. Private treatment through a regulated online pharmacy is the practical alternative for many people who don't meet the current NHS thresholds or prefer not to wait. The weight loss treatment overview sets out what's available and why clinical oversight matters regardless of the route you choose.

How do you know an online pharmacy is genuine before you hand over any details?

This matters more for prescription medicines than almost anything else you'd buy online. The GPhC (the pharmacy regulator in Great Britain) maintains a public register of every registered pharmacy premises. Any legitimate online pharmacy operating legally in the UK will appear on it. You can search by name or registration number at the GPhC pharmacy register. nume's registration number is 9012878, verifiable directly at that link.

The MHRA has issued repeated warnings about fake weight-loss pens being sold through social media and unofficial websites. In October 2025, enforcement teams raided the first illicit UK site manufacturing counterfeit tirzepatide pens. Fake pens have been found to contain insulin rather than the labelled medicine, a potentially life-threatening substitution. Red flags to watch for: sellers offering these medicines without a prescription, prices far below the market rate, and discount codes from unverified sources. Report suspect sellers via the MHRA Yellow Card scheme. A small saving on a prescription medicine is not worth the risk; it's simply the wrong measure to apply here.

If you want to understand more about what makes a registered pharmacy different from an unverified seller, our page on using a registered pharmacy for Mounjaro covers this in detail.

Who is eligible for Mounjaro 10mg, and does BMI alone decide it?

The licensed eligibility criteria for private treatment are: adults with a BMI of 30 or above, or a BMI of 27 or above alongside at least one weight-related health condition such as high blood pressure, type 2 diabetes, high cholesterol or obstructive sleep apnoea. Lower BMI thresholds can apply for some ethnic backgrounds under UK clinical guidance. These are the criteria the prescriber works from, but BMI alone is never the whole picture. A prescriber reviews your full health history before any prescription is issued.

At 10mg specifically, the clinical question is whether you've been titrating appropriately and tolerating the treatment well. Jumping to 10mg from an earlier dose without that escalation path isn't something a responsible prescriber would approve. If you're transferring from another provider at this dose, you'll be asked for evidence of your current treatment, that's standard clinical practice, not extra bureaucracy. Our FAQs answer common questions about transfers and repeat orders.

For a broader look at how all Mounjaro doses fit together, the Mounjaro stock and availability page covers what to expect across the titration journey. And if you're currently on 5mg and considering the next step, the 5mg access page explains how that dose transition is handled clinically, while patients approaching the higher end of the titration schedule can find current availability information on our page covering Mounjaro 12.5mg stock.
