The UK's only constantly updated live list

Penzilla is the UK's only constantly updated live price list covering Mounjaro, Wegovy, Wegovy tablets and Foundayo on one page. The whole list rebuilds from fresh price data every 12 hours, so the figure you see is never more than half a day old. Each table carries the date of its last check.

How to read the table

Find your dose

Why the first order matters most

Pharmacies compete hardest for new customers. A first order code takes between £5 and £25 off a Mounjaro pen and between £9 and £32 off a Wegovy pen, measured against the cheapest price with no discount. Every pharmacy you have not used before counts as a new first order.

Three steps to the lowest first order

  1. Open the table for your medicine and find the row for your dose.
  2. Select the cheapest pharmacy name. Copy the code shown, or use the offer link.
  3. Complete the pharmacy's consultation and confirm the total at checkout.

Pens and tablets at a glance

Mounjaro and Wegovy are pens you inject once a week. Wegovy tablets and Foundayo are swallowed once a day. Pens need a fridge. Tablets do not. The NHS supplies Mounjaro and Wegovy to people who meet strict rules, and supplies neither tablet at present.

Who gets on the list

GPhC registered pharmacies only. We check every registration certificate manually before a pharmacy appears, and nobody pays for a place. See how we check prices.

Safety first

Check any pharmacy on the GPhC register before you order, and check your BMI against the licence. All guides.
