How to Get £40 Off the Best Weight Loss Injection

Claim Your £40 Discount on Mounjaro Today

Use discount code FIRST40 at checkout to save £40 on your first Mounjaro order. This brings our 2.5mg starter pen down to just £129.99, making it one of the most competitive prices for this prescription weight management injection in the UK. The code applies automatically during checkout, with no minimum order required.

Why Mounjaro is the Best Weight Loss Injection UK

Mounjaro (tirzepatide) is a once-weekly injectable that activates two natural hormones - GIP and GLP-1. This dual action may help regulate appetite and promote feelings of fullness, potentially reducing food cravings when used alongside a reduced-calorie diet and increased physical activity. As a prescription-only medicine under MHRA monitoring, it requires clinical assessment before dispensing.

First-Time Customer Pricing with FIRST40

Our discounted first-order pricing makes starting your weight management journey more affordable. Single pens start from £129.99 (2.5mg) after your £40 discount. Popular bundle options include our Intro Duo (2.5mg + 5mg pens) for £299.99 first order, or the comprehensive Intro Trio for £534.99, covering your initial 12-week treatment period.

Fast Clinical Assessment and Approval

Complete your online clinical assessment in minutes. Our qualified prescribers review applications within 3 working days as standard, or upgrade to express 24-hour approval. Once approved, your Mounjaro ships discreetly from our GPhC-registered facility with tracked delivery. No GP visit required - everything handled online.

How to Apply Your Discount Code

Simply add your chosen Mounjaro strength to basket, proceed to checkout, and enter FIRST40 in the discount code field. Your £40 saving applies immediately. Returning customers save £25 on every future order automatically. Start your clinical assessment now to secure your discounted first order.

Bundle Deals for Maximum Savings

Combine your FIRST40 discount with our money-saving bundles. The Progress Trio (5mg, 7.5mg, 10mg) costs £634.99 for first-time customers - a significant saving versus buying individual pens.
