How to Use Your FIRST40 Discount Code

Apply Code FIRST40 for Maximum Savings

Save £40 on your first Mounjaro prescription by entering discount code FIRST40 at checkout. This exclusive offer reduces your first pen cost significantly - 2.5mg starter pen drops from £169.99 to just £129.99, while the popular 5mg strength reduces from £199.99 to £159.99. The discount applies automatically when you complete clinical assessment and proceed to payment.

Bundle Savings with FIRST40 Code

Maximise your savings by combining FIRST40 with our starter bundles. The Intro Duo (2.5mg + 5mg pens) drops from £339.99 to £299.99 with your discount code, giving you two months of treatment at exceptional value. Progress Duo (5mg + 7.5mg) reduces from £409.99 to £369.99, perfect for continuing your weight management programme. Apply FIRST40 during checkout to unlock these bundle prices.

Express Approval with Your Discount

Your FIRST40 discount code works with both standard and express approval services. Standard clinical assessment takes 3 working days and includes comprehensive medical review. Upgrade to express 24-hour approval for faster treatment start - ideal when you want to begin your prescription fat jab programme immediately. Both services include the same thorough clinical assessment by UK-registered prescribers.

Ongoing Savings for Returning Customers

After using FIRST40 on your initial order, returning customers receive £25 off every subsequent prescription. This means your 2.5mg pen costs £144.99, 5mg costs £174.99, and higher strengths remain competitively priced. Bundle deals also include returning customer discounts, making ongoing treatment more affordable than searching for "fat jabs near me" repeatedly.

Complete Your Order with FIRST40

Ready to claim your £40 discount? Complete our clinical assessment questionnaire, select your preferred Mounjaro strength, and enter FIRST40 at checkout. Our GPhC-registered pharmacy team will review your assessment and arrange prescription dispensing. Free delivery ensures your treatment arrives discreetly within 1-2 working days of approval.
