Monthly Cost Breakdown: Best Weight Loss Injections UK

Mounjaro Monthly Cost Comparison

When choosing the best weight loss injection, monthly cost is a crucial factor for budgeting your treatment. Mounjaro (tirzepatide) offers the most effective prescription weight loss support, with flexible monthly pricing to suit your budget and treatment stage.

Starting Dose Monthly Costs

Your first month with Mounjaro 2.5mg costs just £129.99 with our first-order discount (code FIRST40). This starting dose helps your body adjust to treatment whilst keeping initial costs low. Regular price is £169.99 monthly, but returning customers pay only £144.99 monthly with automatic £25 discount.

Maintenance Dose Monthly Costs

Most patients progress to 5mg monthly, costing £159.99 for first orders or £174.99 for returning customers (regular £199.99). Higher maintenance doses include 7.5mg at £209.99 first order (£224.99 returning, £249.99 regular) and 10mg at £229.99 first order (£244.99 returning, £269.99 regular).

Bundle Options Reduce Monthly Spend

Our 2-pen bundles spread costs across multiple months whilst securing lower per-pen pricing. The Intro Duo (2.5mg + 5mg) costs £299.99 first order, covering your first two months for £149.99 monthly average. Progress Duo (5mg + 7.5mg) costs £369.99 first order, averaging £184.99 monthly.

Maximum Strength Monthly Costs
