Single Pen Doses: Find Your Perfect Starting Point

Complete Single Pen Range Available

Our prescription-only Mounjaro single pens offer flexibility for every stage of your weight management journey. Each pen contains one week's treatment of tirzepatide, designed to work alongside your reduced-calorie diet and increased physical activity programme.

2.5mg Starting Dose - £129.99 First Order

Perfect for treatment beginners, our 2.5mg single pen helps your body adjust to tirzepatide therapy. This lowest dose may help reduce initial side effects while activating GIP and GLP-1 hormones to support appetite regulation. Regular price £169.99, new customers save £40.

5mg Progressive Dose - £159.99 First Order

Most patients progress to 5mg after completing their 2.5mg introduction. This intermediate strength can support enhanced appetite control and feeling of fullness. Single pen priced at £199.99 normally, first-time buyers benefit from substantial savings.

Higher Strength Options: 7.5mg to 15mg

Advanced users requiring stronger doses can select from 7.5mg (£209.99 first order), 10mg (£229.99 first order), 12.5mg (£259.99 first order), or maximum 15mg strength (£278.99 first order). Each higher dose may provide enhanced appetite suppression for established users.

Clinical Assessment Process

Every single pen order requires clinical assessment by our qualified prescribers. Complete your online consultation covering medical history, current medications, and weight management goals. Standard approval takes 3 working days, with express 24-hour processing available for urgent orders.

How Single Pens Work

Mounjaro activates two natural hormone pathways - GIP and GLP-1 receptors. This dual action may help regulate appetite, promote feeling of fullness, and reduce food cravings when combined with lifestyle modifications. Each single pen delivers precisely measured weekly doses.

Returning Customer Benefits

Existing customers save £25 on every single pen order. Our 2.5mg pens cost £144.99, 5mg £174.99, and higher strengths proportionally reduced. Build your treatment programme gradually with consistent savings on repeat orders.
