Choose Your Mounjaro Single Pen Dose

Complete Range of Single Pen Doses

Our single pen service caters for patients at every stage of their Mounjaro treatment journey. Whether you're starting at 2.5mg or maintaining at 15mg, each pen provides four weeks of once-weekly injections. The 2.5mg starter pen costs £169.99, whilst the highest 15mg maintenance dose is £318.99. First-time customers save £40 on any single pen purchase using code FIRST40.

Flexible Dosing Options

Mounjaro treatment typically begins with 2.5mg weekly for four weeks, before increasing to 5mg. Your prescriber may recommend further increases to 7.5mg, 10mg, 12.5mg, or the maximum 15mg dose based on your response and tolerance. Single pen purchases allow complete flexibility to adjust your treatment without committing to multiple pens. Each dose escalation should be made under clinical supervision through our online consultation service.

Professional Online Prescribing

Every Mounjaro purchase requires a prescription from our qualified UK prescribers. Complete the clinical assessment detailing your medical history, current medications, and weight management goals. Standard approval takes 3 working days, though express 24-hour processing is available for urgent requirements. Our prescribers ensure Mounjaro is clinically appropriate and provide personalised dosing recommendations for your single pen purchase.

Prescription-Only Weight Management

Mounjaro contains tirzepatide, a prescription-only medicine that activates GIP and GLP-1 receptors to support appetite regulation. It may help reduce food cravings and promote feelings of fullness when used alongside a reduced-calorie diet and increased physical activity. This dual-action approach can support sustainable weight management as part of a comprehensive lifestyle programme. Single pen purchases ensure you can monitor your individual response before committing to larger quantities.

Returning Customer Benefits

Returning customers receive £25 off every single pen order, making ongoing treatment more affordable. The 5mg pen drops to £174.99 for existing patients, whilst the 10mg maintenance dose costs £244.99. Regular customers also benefit from streamlined reordering and faster approval times as our prescribers become familiar with your treatment history. Set up automatic reminders to ensure continuous treatment without interruption.

Secure UK Delivery Service

All single pen orders are dispatched from our GPhC-registered pharmacy via secure tracked delivery. Packaging is completely discreet with no external indication of contents. Standard delivery takes 2-3 working days following prescription approval, with next-day options available. Orders placed before 2pm with express approval can be delivered the following working day. Track your order online and receive SMS updates throughout the delivery process.
