Mounjaro 5mg Single Pen - Best Value in the UK

Our Mounjaro 5mg single pen offers exceptional value for UK customers seeking prescription-only tirzepatide treatment. At £159.99 for first-time buyers (regular price £199.99), we provide the cheapest legitimate supply available. Each pen contains four weeks of once-weekly injections, making it perfect for those wanting to trial the medication or continue their established routine.

Why Choose a Single 5mg Pen?

The 5mg dose represents the second step in most Mounjaro treatment programmes. After completing the initial 2.5mg dose, many patients progress to 5mg for enhanced appetite regulation. Our single pen option allows flexibility - you can assess your response before committing to larger quantities. This approach suits budget-conscious customers and those preferring to order monthly.

Prescription Process Made Simple

Every Mounjaro purchase requires clinical assessment by our qualified prescribers. Complete our comprehensive online consultation covering your medical history, current medications, and weight management goals. Our team reviews submissions within three working days, or upgrade to express service for 24-hour approval. Once approved, your 5mg pen ships discreetly to your chosen address.

All Mounjaro Single Pen Doses Available

Beyond 5mg, we stock every Mounjaro strength as individual pens. Start with 2.5mg at £129.99 (first order), progress through 7.5mg (£209.99 first order), 10mg (£229.99), 12.5mg (£259.99), up to 15mg (£278.99). Returning customers enjoy £25 off every order, making ongoing treatment more affordable.

Genuine UK-Licensed Medication

All our Mounjaro pens come directly from licensed UK wholesalers to our GPhC-registered pharmacy. Each pen carries full MHRA authentication and proper cold-chain storage certification. You receive the same medication supplied to NHS trusts and private clinics, ensuring complete authenticity and safety.

Treatment Bundle Alternatives

While single pens offer maximum flexibility, consider our bundle options for better value. The Progress Duo (5mg + 7.5mg) costs £369.99 for first orders, saving £30 compared to individual purchases. The Intro Trio covering 2.5mg, 5mg, and 7.5mg provides three months' treatment progression for £534.99 initially.

Delivery and Support

Every order includes free UK delivery with tracking confirmation. Our customer support team provides ongoing guidance throughout your treatment journey. Access injection technique videos, dietary advice, and 24/7 support for any concerns. We also offer convenient repeat prescription services to ensure continuity.
