Calculate Your Monthly Slimming Injection Cost

Monthly Slimming Injection Costs Breakdown

Understanding your monthly investment in prescription-only Mounjaro treatment helps you budget effectively. Each pen provides exactly four weeks of once-weekly injections, making cost calculation straightforward. New patients benefit from significant first-order savings, while returning customers enjoy ongoing discounts on every purchase.

First Month Costs with £40 Discount

Your initial monthly investment is reduced with our FIRST40 discount code. Starting doses cost £129.99 for 2.5mg pens (regular £169.99), while maintenance doses like 10mg cost £229.99 monthly (regular £269.99). This first-month saving makes beginning treatment more affordable while you establish your routine alongside diet and exercise modifications.

Ongoing Monthly Costs for Returning Customers

After your first order, every subsequent purchase qualifies for £25 OFF with automatic returning customer pricing. Your 2.5mg monthly cost becomes £144.99, while higher-dose 15mg pens cost £293.99 monthly. These consistent savings reduce your ongoing treatment investment throughout your weight management journey.

Bundle Options to Reduce Monthly Spend

Multi-pen bundles can lower your effective monthly cost when purchasing treatment in advance. The Intro Duo bundle (2.5mg + 5mg pens) costs £299.99 for first-time buyers, providing two months' treatment at £149.99 per month. Progress Trio bundles offer three months of graduated dosing from £534.99, reducing monthly costs to approximately £178.33 per pen.

Higher Dose Monthly Investment

Maintenance doses require higher monthly investment but may provide enhanced appetite regulation support. Monthly costs for 12.5mg pens are £274.99 for returning customers, while maximum 15mg doses cost £293.99 monthly. Your prescriber will determine appropriate dosing during clinical assessment, ensuring your monthly spend aligns with clinical requirements.
