Choose Your Single Pen Dosage Strength

Single Pen Pricing - All Dosage Strengths Available

Our weight loss drugs online are available as individual pens, allowing you to purchase exactly what you need. Each prescription-only Mounjaro pen contains four doses for one month of treatment. First-time buyers benefit from significant savings with our FIRST40 discount code.

Available single pen strengths: 2.5mg pen from £129.99 (first order), 5mg pen from £159.99 (first order), 7.5mg pen from £209.99 (first order), 10mg pen from £229.99 (first order), 12.5mg pen from £259.99 (first order), and 15mg pen from £278.99 (first order). Returning customers receive £25 off every subsequent order.

Why Choose Single Pen Purchase

Buying a single pen gives you complete flexibility in your weight management approach. Whether you're starting treatment, adjusting your dosage, or continuing maintenance therapy, single pen purchase allows you to order precisely what your treatment plan requires without overcommitting to multiple pens.

Each pen undergoes clinical assessment by UK-registered doctors, ensuring your prescription-only medication is appropriate for your individual circumstances. The tirzepatide injection may help regulate appetite and promote feelings of fullness when used alongside reduced-calorie diet and increased physical activity.

Fast UK Approval and Delivery

Standard clinical approval takes 3 working days, with express 24-hour approval available as a paid upgrade. All orders are fulfilled by our GPhC-registered UK pharmacy, ensuring you receive genuine prescription-only medication with full regulatory compliance.

Your single pen order includes comprehensive injection guidance and ongoing support. The once-weekly injection activates GIP and GLP-1 hormones that can support appetite regulation and may help reduce food cravings as part of your overall weight management strategy.

Order Your Single Pen Today

Complete your clinical assessment online and select your required dosage strength. Use code FIRST40 for £40 off your first order, or enjoy automatic £25 savings as a returning customer. Express approval ensures you can start treatment within 24 hours if required.
