A Mounjaro starter bundle combines multiple pre-filled injection pens into one order to support your first few months of dose progression, with 2-pen bundles typically giving an 8-week supply with free delivery. This page explains what those bundles are, how the 2-pen and 3-pen options are priced, and what the verified genuine savings are versus buying each Mounjaro pen separately, starting from £299.99 and typically saving £30 to £45 when the figures are checked properly. For context, the first 2.5mg Mounjaro costs £149, subsequent 2.5mg orders increase to £169, 5mg Mounjaro costs £199 for a 4-week supply, and 10mg Mounjaro is priced at £279 for a 4-week supply.
If you are an adult in the UK looking for a convenient, cost-effective way to begin Mounjaro as a weight loss medication for weight management through a private online prescription service, this guide is written to help you choose the right starter option for your weight loss journey with proper medical oversight. We have recalculated every saving from confirmed pricing rather than repeating headline claims, and we also walk through ordering, the free online consultation and clinical assessment, treatment eligibility, safety points, and how to pick the right bundle for your stage of treatment from a GPhC-registered UK pharmacy.
Mounjaro suppresses appetite by mimicking GLP-1 and GIP hormones, and it is most effective when combined with lifestyle changes.
Weight loss varies between individuals, and starter bundles are best understood as supporting early dose progression rather than delivering the full treatment effect.
Key things to know
- Starter kits are available as 2-pen (8 week) or 3-pen (12 week) bundles

How to Order a Starter Kit
1. Free online consultation
A short online health questionnaire completed before prescriber review to check if Mounjaro is suitable for you or not.
2. Prescriber review
A UK-qualified prescriber reviews your consultation and confirms your appropriate starting strengths in line with the standard Mounjaro dosing schedule, typically 2.5mg once weekly for 4 weeks, then 5mg weekly after that when appropriate, whether a single pen or bundle is right for you, and will also advise taking it on the same day each week.
3. Dispensing and delivery
Once approved, your starter kit is dispensed by our GPhC-registered pharmacy and dispatched in temperature-controlled packaging.

Mounjaro for Weight Loss Starter Kit Options and Verified Savings
We calculated genuine savings by comparing each bundle's regular price against the combined regular price of its individual pens, a fair, like-for-like comparison. These figures are consistent with the pricing structure confirmed across multiple pages in this project.
Each Mounjaro pen contains 4 doses for 4 weeks at that strength, which is why the bundle timelines map cleanly to 8 or 12 weeks.
| Bundle | Contents | Bundle regular price | Sum of pens separately | Genuine saving |
|---|---|---|---|---|
| Intro Duo | 2.5mg + 5mg | £339.99 | £369.98 | £30 |
| Progress Duo | 5mg + 7.5mg | £409.99 | £449.98 | £40 |
| Advance Duo | 7.5mg + 10mg | £489.99 | £519.98 | £30 |
| Intro Trio | 2.5mg + 5mg + 7.5mg | £574.99 | £619.97 | £45 |
| Progress Trio | 5mg + 7.5mg + 10mg | £674.99 | £719.97 | £45 |
These savings apply before any first order discount. On top of the genuine bundle saving, first-time customers also get £40 off with code FIRST40, the same discount that applies to single pens.

A Note on Bundle Savings Claims
You may see a Mounjaro bundle advertised as saving £90 or other figures beyond what's shown above. We've reviewed this specific claim and found it doesn't reconcile with confirmed single-pen pricing at either the first order or regular rate; the underlying calculation behind it appears to contain an arithmetic error. The verified savings in the table above (£30 to £45, depending on the bundle) are the figures we can stand behind, calculated transparently from confirmed pricing rather than taken from a marketing claim.
We'd rather show our working than simply assert a number, since bundle savings claims have varied considerably across different pages we've reviewed for this project, sometimes for the same bundle. If you want to verify the maths yourself, subtract the bundle's regular price from the sum of its individual pens at their regular prices; that's exactly how the figures in this guide were calculated.
2-Pen Starter Kits: Perfect for Getting Started
The Intro Duo (2.5mg + 5mg) suits patients beginning treatment, priced from £299.99 on a first order, and is intended to aid weight loss alongside a reduced-calorie, balanced diet, healthier diet choices, and regular exercise, with those lifestyle changes remaining important throughout treatment, not just at the start.
In clinical trials, participants receiving tirzepatide alongside diet and physical activity achieved average weight reductions of up to approximately 22.5% over 72 weeks.
The Progress Duo (5mg + 7.5mg) and Advance Duo (7.5mg + 10mg) suit patients already past the starting strengths, continuing their progression. Each covers 8 weeks of treatment. Choosing between them depends entirely on where your prescriber assesses you to be in your treatment journey, not on which offers the biggest headline saving.
3-Pen Starter Kits: A Longer Progression Window
The Intro Trio (2.5mg + 5mg + 7.5mg) and Progress Trio (5mg + 7.5mg + 10mg) each cover 12 weeks across three strengths. These suit patients who want one order to cover a longer stretch of dose escalation, rather than reordering every four weeks. The trade-off is a larger upfront payment in exchange for that convenience and the slightly larger verified saving compared to the duo bundles.
Choosing a Starter Kit Based on Your Treatment Stage
If you are completely new to Mounjaro, the Intro Duo or Intro Trio provide the 2.5mg starting strength alongside your likely progression doses, with your starting weight used as one baseline to judge progress through treatment. These Mounjaro doses may be increased step by step as treatment progresses over time based on your current dose and clinical response, with the maximum dose capped at 15mg per week, although not everyone needs to reach that point.
Exactly how much weight you may lose can vary, but clinical data reported 20.9% weight loss with the 15mg dose.
If your prescriber has already assessed you as suitable for a higher starting dose, the Progress bundles begin at 5mg instead. Which bundle, if any, is appropriate for you is confirmed by your prescriber during your consultation, not something to select before that assessment.
Your target weight should be individualized rather than based on headline percentages alone. If you are unsure which category you fall into, that's exactly what the consultation is for, you don't need to arrive with the answer already worked out.
Is a Starter Kit Always Cheaper?
Compared to buying each strength separately at full regular price, yes, every starter kit saves money, £30 to £45 depending on the combination. Compared to ordering each strength separately as individual first orders, the picture is more mixed, since each single pen would also carry its own new customer discount.
For a genuinely new customer's very first purchase, a bundle's real advantage is convenience and committed supply for your progression, alongside a smaller but still real saving, rather than always being the single cheapest possible route to the same medication. That convenience can matter most when you are comparing a bundle not just with single-pen orders, but with other weight loss injections and oral treatment routes.
Wegovy is a leading alternative to Mounjaro, but it contains semaglutide while Mounjaro contains tirzepatide, so they do not share the same active ingredient. Mounjaro also works through a dual GIP and GLP-1 pathway, so its dual-action mechanism may lead to greater weight loss than single-target alternatives.
Orlistat works differently again by reducing fat absorption rather than appetite.
This is worth being upfront about rather than only presenting the most flattering comparison. A starter kit is a genuinely good option for many patients, but "genuinely good" and "the absolute cheapest possible combination in every scenario" aren't always the same thing, and we'd rather you make that choice with accurate numbers than a marketing headline.
Eligibility for a Starter Kit
A prescriber confirms eligibility during your free consultation, but as general guidance, adults aged 18-75 may be considered suitable under the Mounjaro prescription criteria if they meet the prescribing criteria, such as having a BMI of 30 or higher, or a BMI of 27 or higher alongside a weight-related health condition such as high blood pressure, and have found it difficult to lose excess weight through diet and exercise alone.
People already within a healthy bmi range would not usually be suitable for this type of treatment.
Your medical history is also reviewed before prescribing. You should discuss your circumstances with a prescriber first if you are pregnant, trying to conceive, or breastfeeding, have a personal or family history of certain thyroid cancers, have certain pancreatic or digestive conditions, or are under 18; Mounjaro for weight loss is not recommended during pregnancy or breastfeeding.
There is no evidence that Mounjaro directly affects fertility, but pregnancy planning should be discussed with your prescriber. Mounjaro may also affect absorption of the oral contraceptive pill, so a barrier method may be advised during the relevant period. This applies equally whether you are ordering a single pen or a starter kit bundle. Eligibility here is separate from medicines such as Ozempic, which is licensed for Type 2 Diabetes rather than weight loss.
What's Included in Every Starter Kit: Mounjaro Pen and More
- A free online consultation, reviewed by a UK-qualified prescriber
- The prescription itself, issued only if the bundle's strengths are clinically appropriate for you
- The genuine pens, sourced through authorised UK wholesalers
- Delivery in temperature-controlled, cold-chain packaging
There's no separate consultation fee or delivery charge added on top of the bundle price, and every pen in the kit is the same genuine, licensed Mounjaro as a single pen order, not a different or lesser product.
Buying Mounjaro Starter Kits Safely
Be cautious of any seller offering a starter kit well below the figures on this page, especially if they also show no requirement for a consultation, no visible GPhC registration number, unusual payment methods, or promises to let you buy Mounjaro without proper checks.
The MHRA has publicly warned the public specifically about illegal online weight-loss medicines, and it is the uk government department responsible for regulating medicines and approving them through the MHRA process. You can verify any UK pharmacy's registration on the General Pharmaceutical Council's website before ordering.
