Calculate Your Monthly Diet Injection Treatment Cost

Monthly Mounjaro Costs - Single Pen Pricing

Your monthly diet injection cost depends on your prescribed dosage strength. Our Mounjaro prescription-only injections start at £129.99 for first-time buyers on the 2.5mg starter dose, rising to £278.99 monthly for the highest 15mg strength. Returning customers benefit from £25 off every order, reducing monthly costs significantly. The 2.5mg starter dose costs just £144.99 monthly for returning customers, whilst the 5mg maintenance dose - commonly prescribed long-term - costs £174.99 monthly after your first discounted order.

Reduce Monthly Costs with Bundle Options

Smart buyers choose our bundle packages to reduce monthly treatment costs during dose escalation phases. The Intro Duo bundle (2.5mg + 5mg pens) provides two months' treatment for £299.99 on your first order - equivalent to just £149.99 monthly. This represents substantial savings versus buying single pens separately, reducing your average monthly diet injection cost during the crucial first two months of treatment.

Long-Term Monthly Budget Planning

Most patients stabilise on 5mg, 7.5mg or 10mg maintenance doses, making monthly budget planning straightforward. The popular 5mg monthly cost is £174.99 for returning customers, whilst the 7.5mg strength costs £224.99 monthly. Our 10mg maintenance dose - often the optimal therapeutic dose - costs £244.99 monthly for returning customers. These transparent monthly costs help you budget effectively for ongoing treatment success.

First Order Savings Reduce Initial Monthly Cost

New customers save £40 on their first order with code FIRST40, dramatically reducing initial monthly treatment costs. Your first 2.5mg pen costs just £129.99, whilst the 5mg dose costs £159.99 initially. This first order discount makes starting your diet injection treatment more affordable, with the full monthly cost only applying from your second order onwards.

How Ongoing Discounts Affect Monthly Costs

Our returning customer discount provides £25 off every order after your first purchase, ensuring your monthly diet injection costs remain competitive long-term. This ongoing saving reduces the standard monthly cost for all dosage strengths, making sustained treatment more affordable. Combined with our bundle options during dose escalation, you can minimise your average monthly treatment expense throughout your weight management journey.
