How to Use Your £40 Discount Code FIRST40

Apply Code FIRST40 for Maximum Savings

Our discount code FIRST40 gives you £40 off your first order of prescription weight loss injections. Simply enter FIRST40 at checkout to unlock the cheapest prices online. This exclusive offer applies to all Mounjaro strengths and bundles, making your weight management journey more affordable.

Cheapest Weight Loss Injection Prices After Discount

With code FIRST40, our already competitive prices become unbeatable. Mounjaro 2.5mg drops to just £129.99 (RRP £169.99), while the 5mg strength costs £159.99 after discount. Our popular Intro Duo bundle containing both starter strengths costs just £299.99 with your discount code - that's £80 savings compared to buying separately at full price.

Calculate Your Total Savings

The FIRST40 discount code delivers substantial savings across our entire range. Order the 7.5mg strength and pay £209.99 instead of £249.99. Choose the Progress Trio bundle and your discount brings the price down to £534.99 from £674.99. Every order qualifies for the full £40 reduction, making us the cheapest option for prescription weight loss injections online.

Quick Order Process with Instant Discount

Ordering with your discount code takes minutes. Select your preferred Mounjaro strength or bundle, complete the clinical assessment, then enter FIRST40 during checkout. Your £40 discount applies immediately, showing your final discounted price before payment. Clinical approval typically takes 3 working days, or upgrade to express 24-hour service.

Why Our Discount Makes the Difference

Beyond the cheapest prices, your FIRST40 code includes everything needed to start treatment. Clinical assessment by UK-qualified prescribers, GPhC-registered pharmacy dispensing, and free discreet delivery are all included. These once-weekly injections may help support appetite regulation and feelings of fullness when used alongside reduced-calorie diet and increased physical activity.

Returning Customer Benefits

After using FIRST40 on your first order, returning customers automatically receive £25 off every subsequent order. This ongoing discount ensures you continue getting the cheapest weight loss injections online throughout your treatment journey. No codes needed for returning customer discounts - savings apply automatically.
