How to Use Your FIRST40 Discount Code

Apply Code FIRST40 for Maximum Savings

Your FIRST40 discount code saves £40 on any first order of Mounjaro, the prescription-only weight loss medicine. This exclusive offer makes proven treatment accessible - Mounjaro 2.5mg starts at just £129.99 instead of £169.99. The code works on all strengths and bundle options, giving you flexibility to choose the right treatment plan.

Mounjaro Prices with FIRST40 Discount

Single pen options with your discount: 2.5mg for £129.99 (save £40 from £169.99), 5mg for £159.99 (save £40 from £199.99), and higher strengths with the same £40 saving. Bundle deals offer even better value - the Intro Duo (2.5mg + 5mg) costs £299.99 with FIRST40, normally £339.99. These bundles support the recommended dose escalation protocol.

Why Choose Mounjaro for Weight Loss

Mounjaro contains tirzepatide, which activates GIP and GLP-1 hormones to regulate appetite and promote fullness alongside reduced-calorie diet and increased physical activity. This prescription-only medicine may help reduce food cravings and support sustainable weight management. Clinical assessment ensures suitability before dispensing.

Your FIRST40 code applies automatically at checkout, reducing your total by £40. All orders include prescription fees and delivery to your door from our GPhC-registered pharmacy.

Returning Customer Benefits

After using FIRST40, returning customers receive £25 off every subsequent order automatically. This ongoing discount ensures continued affordability for your weight loss journey. Most customers progress through different Mounjaro strengths, making regular ordering convenient and cost-effective.
