Choose Your Single Pen Dose Today

Complete Single Pen Range Available

Our single pen options give you the flexibility to order exactly what you need. Whether you're starting your weight management journey with the 2.5mg dose or maintaining progress with higher strengths, we stock all six Mounjaro doses as individual pens. Each pen contains four weeks of treatment, making it easy to manage your prescription-only medication alongside your reduced-calorie diet and exercise programme.

Single Pen Pricing - Start From £129.99

New customers enjoy significant savings with our first order discount. The 2.5mg starter pen costs just £129.99 for first-time buyers (regular price £169.99), while the popular 5mg pen is available for £159.99 first order (£199.99 regular). Higher doses include 7.5mg at £209.99 first order, 10mg at £229.99, 12.5mg at £259.99, and the maximum 15mg dose at £278.99 for new customers. Returning customers receive £25 off every order, ensuring ongoing value for your weight management treatment.

Why Choose Single Pen Orders

Single pens offer the perfect solution for those who prefer to order monthly rather than commit to multi-pen bundles. This approach allows you to adjust your treatment plan with your prescriber's guidance, ensuring you're always on the most appropriate dose. The flexibility of single pen ordering also means you can trial the medication without a larger upfront investment, making it easier to start your weight loss journey with confidence.

Clinical Assessment and Prescription Process

Every single pen order includes a comprehensive clinical assessment by our qualified prescribers. This prescription-only medication requires medical evaluation to ensure it's suitable for your individual circumstances. Our streamlined online consultation takes just minutes to complete, with standard approval within 3 working days or express 24-hour service available. The assessment covers your medical history, current medications, and weight management goals to ensure safe and effective treatment.

How Mounjaro Single Pens Support Weight Loss

Each single pen contains tirzepatide, which activates GIP and GLP-1 receptors - two natural hormones that regulate appetite and promote feelings of fullness. This dual action may help reduce food cravings and support portion control when combined with lifestyle changes. The once-weekly injection schedule makes it convenient to maintain consistent treatment levels, supporting your long-term weight management goals alongside reduced-calorie eating and increased physical activity.

Order Your Single Pen Today

Don't wait to start your weight management journey. Our single pen options provide the flexibility and value you need to begin treatment with confidence. With first order savings of £40 and ongoing discounts for returning customers, there's never been a better time to order. Complete your clinical assessment today and take the first step towards achieving your weight loss goals with the UK's most trusted online pharmacy for prescription weight management medication.
