Why Choose Single Pen Purchase?

Buying individual Mounjaro pens offers maximum flexibility for your treatment journey. Whether you're beginning with the 2.5mg starter dose or maintaining on a higher dose, single pen purchase allows you to order precisely what you need without committing to larger quantities upfront.

Each pen contains four doses for one month's treatment, making our single pen option ideal for testing tolerance, adjusting between doses, or maintaining steady supply without bulk purchasing.

First Order Savings

New customers save £40 on every pen with code FIRST40. This brings your first 2.5mg pen down to just £129.99 - the cheapest Mounjaro price available in the UK. Higher doses also benefit from the same £40 reduction, making your first 15mg pen £278.99 instead of £318.99.

Returning customers automatically receive £25 off every order, ensuring continued value whether you're ordering single pens or progressing through doses.

Clinical Assessment Included

Every single pen purchase includes comprehensive clinical assessment by our qualified prescribers. This prescription-only medicine requires proper medical evaluation to ensure suitability and safety for your individual circumstances.

Standard assessment completes within 3 working days, with express 24-hour service available for urgent requirements. All assessments meet MHRA guidelines and GPhC standards for online prescription services.

How Mounjaro Works

Mounjaro (tirzepatide) activates GIP and GLP-1 receptors - two natural hormone pathways that may help regulate appetite and promote feelings of fullness. This dual-action approach can support weight management when used alongside reduced-calorie diet and increased physical activity as prescribed.

The once-weekly injection is designed to fit seamlessly into your routine, with each pen providing exactly four weeks of treatment at your prescribed dose.
