How Prescription Slimming Drugs Work

Mounjaro (tirzepatide) is a prescription-only weekly injection that may help support weight management goals. The medication activates GIP and GLP-1 - two natural hormones that regulate appetite and promote feelings of fullness. This can support reduced calorie intake when used alongside a structured diet and exercise programme.

How to Apply Code FIRST40

1. Select your prescribed Mounjaro dose or bundle
2. Complete the online clinical assessment
3. Enter code FIRST40 at checkout
4. Your £40 discount applies automatically
5. Receive approval within 3 working days (or 24 hours with express)

Ongoing Savings for Regular Customers

After using your first-order discount, returning customers receive £25 off every subsequent order automatically. This means continued savings on your weight management treatment journey.

Clinical Assessment Required

All prescription slimming medications require clinical assessment by our registered prescribers. This ensures the treatment is suitable for your individual health profile and weight management goals. Assessment typically takes 3 working days, with express 24-hour options available.
