Why the 10mg price matters most
Mounjaro is titrated slowly to reduce side effects. You start on 2.5mg for four weeks (a starter dose, not a treatment dose), then step up to 5mg, and increase in 2.5mg increments — 7.5mg, then 10mg — after at least four weeks each, up to a maximum of 15mg.
10mg is a common maintenance dose. Many people find it gives strong results without needing to push to the top of the range, so it's often where you'll spend the most months of your treatment. In the SURMOUNT-1 trial, participants on 10mg lost an average of 21.4% of body weight over 72 weeks — very close to the 22.5% seen on 15mg.
That's why a first-month promo code on the 2.5mg starter dose, while nice, shouldn't drive your decision. The 10mg ongoing price is the number that shapes your real long-term spend. A £30-a-month difference here adds up to nearly £400 across a year on this dose alone.
Our recommended provider for 10mg
We recommend The Weight Clinic not because they're the rock-bottom cheapest on every dose, but because they combine competitive pricing with genuinely useful support: monthly video reviews with a prescriber, a £35-off-first-order code (NEWME), and a refund if the prescriber decides Mounjaro isn't right for you. Their 10mg price is £260 per four weeks, with a first month at £125 on the starter dose.
If your only priority is the lowest possible 10mg figure, the pharmacies at the top of the table above will save you more each month. Both routes are legitimate — it's a trade-off between price and hand-holding. What matters is that whoever you choose is UK-regulated.
How to tell a cheap 10mg deal from a dodgy one
Cheap does not mean dodgy — but genuinely cheap and genuinely dodgy can look similar at a glance. Here's how to spot the difference:
- Check the register. A legit pharmacy is GPhC-registered; a clinic should be CQC-regulated. You can search both registers for free.
- Expect a consultation. Mounjaro is a prescription-only medicine. No questions, no prescription, no deal — walk away.
- Genuine brand only. You want brand Mounjaro pens from Eli Lilly. Avoid anything described as "compounded" tirzepatide or vials sold without a prescription — these are unregulated and unsafe.
- Sensible pricing. A price wildly below the £229 floor should make you cautious, not excited.

What about the other doses?
If you're not on 10mg yet, it's worth knowing the price at your current dose and the one you'll step up to. The 5mg dose is a natural comparison point — see our cheapest Mounjaro 5mg guide — and our year cost planner maps out realistic dose-by-dose totals across 12 months.
Because most people move through several doses, the cheapest provider for you is the one that stays competitive across the range, not just on one pen.
Ready to start or switch?
The Weight Clinic is our recommended provider: 10mg at £260 per four weeks, £35 off your first order with code NEWME, monthly video reviews, and a full refund if the prescriber declines your request.
A note on side effects
Common side effects include nausea, diarrhoea, constipation, vomiting and tiredness. Rare but serious risks include pancreatitis and gallstones. If you experience a side effect, you can report it through the MHRA Yellow Card scheme. Always follow the guidance of your prescriber.
Frequently asked questions
What is the cheapest Mounjaro 10mg in the UK right now?
As of 24 August 2026, Medicine Marketplace has the lowest ongoing 10mg price at £229 per four weeks, followed by Next Script and PillSphere at £230. Always confirm the live price on the pharmacy's own website, as prices change often.
Why does the 10mg price matter more than a first-month deal?
10mg is a common maintenance dose where many people stay for months, so it drives your real long-term spend. First-month promo codes usually target only the 2.5mg starter dose, so the 10mg ongoing price is the more important number to compare.
Are these cheap 10mg prices legitimate?
Yes. Every provider in our table is UK-regulated — GPhC-registered or working with a CQC-regulated online doctor — and dispenses genuine brand Mounjaro after an online consultation. What's not legitimate is any seller offering Mounjaro with no prescription or an unregulated "compounded" version.
How much will a year on 10mg cost?
At the cheapest 10mg price of £229 every four weeks, a full year would work out around £2,977 if you stayed on 10mg throughout. Most people move through several doses, though — our year cost planner breaks down realistic dose-by-dose totals.
Can I use a discount code on the 10mg dose?
Some codes apply only to the 2.5mg starter dose, while others give ongoing savings. Check each code's terms — our verified discount codes guide lists which work and where. The Weight Clinic's NEWME code gives £35 off your first order.
Do I need a subscription to get the cheap 10mg price?
No. Several of the lowest 10mg prices come from pay-as-you-go pharmacies with no membership fee. Subscription services can suit people who want bundled coaching, but you never have to sign up to a plan to access a competitive Mounjaro price.
