Our single pen options cover the full treatment range, from starter 2.5mg pens to maximum strength 15mg doses. Each pen contains four weeks of once-weekly injections, making them perfect for trial periods or maintaining your current prescription strength.

Single Pen Pricing - Transparent and Competitive

Our single weight loss injection pens start from £169.99 for the 2.5mg dose, with first-time buyers saving £40 using code FIRST40. The 5mg pen costs £199.99 (£159.99 first order), while higher doses range up to £318.99 for the 15mg strength. Returning customers receive £25 off every order, ensuring ongoing value for your weight management investment. All prices include clinical assessment, prescription, and secure UK delivery.

Perfect for Flexible Treatment Plans

Single pens offer maximum flexibility for your weight loss journey.
