Choose Your Mounjaro Single Pen Dose

Mounjaro Single Pen Pricing

Our single pen options cater for every stage of your weight management journey. Starting doses begin at £129.99 for first-time buyers, with all six available doses stocked as individual pens. The 2.5mg starter dose costs £169.99 (£129.99 first order), whilst the highest 15mg dose is £318.99 (£278.99 first order). Each pen delivers four weekly doses, providing one month's treatment.

Complete Dose Range Available

We stock all Mounjaro doses as single pens: 2.5mg (£169.99), 5mg (£199.99), 7.5mg (£249.99), 10mg (£269.99), 12.5mg (£299.99), and 15mg (£318.99). First-time buyers save £40 with code FIRST40, whilst returning customers receive £25 off every order. This flexible approach means you can purchase exactly what you need without committing to larger bundles.

Why Choose Single Pen Purchase

Single pens offer maximum flexibility for your treatment. Whether you're starting your weight management journey or maintaining your current dose, purchasing individual pens allows you to adjust your order based on your clinical needs. This prescription-only medicine requires clinical assessment, and our single pen option lets you trial your prescribed dose before considering larger quantities.

Clinical Assessment Process

Every Mounjaro purchase requires clinical assessment by our qualified prescribers. Standard assessment takes 3 working days, with express 24-hour approval available as a paid upgrade. Our GPhC-registered pharmacy ensures full compliance with MHRA regulations. Once approved, your single pen ships with full prescribing information and injection guidance.

How Mounjaro Works

Mounjaro (tirzepatide) activates two natural hormones - GIP and GLP-1 - which may help regulate appetite and promote feelings of fullness. This prescription-only injectable is designed to be used alongside a reduced-calorie diet and increased physical activity. The once-weekly injection schedule makes it convenient to incorporate into your routine.
