Choose Your Single Weight Loss Injection Pen

Complete Single Pen Range Available

Our single-pen service provides access to all Mounjaro dose strengths for individual purchase. The 2.5mg starter pen costs £169.99 (£129.99 for first-time buyers), while the 5mg pen is priced at £199.99 (£159.99 with new customer discount). Higher doses include 7.5mg pens at £249.99, 10mg at £269.99, 12.5mg at £299.99, and the maximum 15mg strength at £318.99. Each pen delivers four weeks of once-weekly treatment to support your weight management goals alongside diet and exercise.

Why Choose Single Pen Ordering

Single-pen purchasing offers maximum flexibility for your prescription needs. You can start treatment without committing to larger quantities, test different dose strengths as prescribed, or maintain your current prescription schedule with individual orders. This approach works particularly well for patients transitioning between doses or those who prefer ordering one month at a time. Our clinical team provides the same comprehensive assessment and ongoing support regardless of order size.

Professional Prescription Service

Every single pen order includes a thorough clinical assessment by our qualified prescribers. As a prescription-only medicine, Mounjaro requires professional evaluation to ensure suitability and safety. Our GPhC-registered pharmacy maintains full regulatory compliance while offering convenient online ordering. The assessment covers your medical history, current medications, and weight management goals to determine the appropriate starting dose and treatment plan.

Fast Approval and Delivery

Standard prescription approval takes three working days, with express 24-hour processing available as a paid upgrade. Once approved, your single pen ships via secure courier with full cold-chain protection to maintain medication integrity. All orders include comprehensive injection guidance, dosing instructions, and access to our patient support team for ongoing assistance throughout your treatment.

Flexible Ordering Options

While single pens provide maximum flexibility, customers can also consider our 2-pen bundles for dose progression convenience. The Intro Duo combines 2.5mg and 5mg pens for £339.99, while the Progress Duo pairs 5mg and 7.5mg strengths at £409.99. Returning customers benefit from £25 off every order, making ongoing treatment more affordable. Choose the ordering pattern that best suits your prescription schedule and budget requirements.

Is GLP-1 treatment right for you?

GLP-1 medicines are powerful and prescription-only for good reason. They suit many people very well — and they aren’t appropriate for everyone. Here’s a clear, honest picture before you decide.
