Calculate Your Monthly Slimming Pen Investment

Monthly Cost Breakdown for UK Slimming Pens

Understanding your monthly slimming pen costs helps you budget effectively for your weight management treatment. Our Mounjaro prescription pens offer clear monthly pricing with significant first-order and returning customer discounts. Starting doses at 2.5mg cost £169.99 monthly, but drop to just £129.99 for your first month with our new customer offer.

First Month Savings Reduce Initial Costs

Your first month benefits from £40 off with code FIRST40. The 2.5mg starter pen costs £129.99 instead of £169.99, while the 5mg pen reduces from £199.99 to £159.99. This first-month saving helps manage initial treatment costs while you begin your prescribed weight management programme alongside reduced-calorie diet and increased physical activity.

Returning Customer Monthly Costs

Continuing treatment remains affordable with £25 off every order for returning customers. Your monthly 2.5mg pen costs £144.99, while 5mg pens cost £174.99 monthly. Higher maintenance doses like 10mg cost £244.99 monthly for returning customers, down from the standard £269.99 price.

Bundle Options Lower Monthly Per-Pen Costs

Multi-pen bundles significantly reduce your monthly per-pen investment. The Intro Duo bundle (2.5mg + 5mg pens) costs £299.99 for first orders - effectively £149.99 per pen monthly when using both pens over two months. The Progress Trio bundle offers even better value at £534.99 for first orders, covering three months of treatment.

Budgeting for Dose Progression

Most patients progress through increasing doses during treatment. Budget for monthly costs increasing from £144.99 (2.5mg returning customer price) to £293.99 (15mg returning customer price) as your prescription may be adjusted. This progression happens gradually, allowing you to plan monthly expenses accordingly.
