What is WeightCompare?
WeightCompare (weightcompare.co.uk) is a free, independent UK price comparison website for Mounjaro (tirzepatide).

What WeightCompare does
WeightCompare compares Mounjaro pharmacy prices so you can see the cheapest legitimate option for your dose before you order. That includes:
- A daily-updated price comparison across 90+ pharmacies — the largest tracked coverage of any UK Mounjaro comparison site
- True first-month total cost, including consultation and delivery fees where pharmacies charge them
- A monthly UK Mounjaro Price Index — average price per dose, month-on-month change, and a free CSV dataset
- Verified pharmacy-published discount codes, price trend charts, and free price-drop alerts
What WeightCompare is not
WeightCompare is not a pharmacy, a clinic, a weight-loss programme, or a visual weight comparison tool. It does not sell or prescribe medication, and it does not provide medical advice. Every pharmacy listed is registered with the General Pharmaceutical Council (GPhC), and listings link to the pharmacy's own website.
How WeightCompare stays independent
The comparison table is ranked by price only — WeightCompare never accepts payment to reorder it. Sponsored placements are clearly labelled and shown separately from the organic ranking. Revenue comes from referral commissions and clearly-marked pharmacy listings, which never affect the price you pay. Full details are in the editorial policy.
Frequently asked questions
What is WeightCompare?
WeightCompare (weightcompare.co.uk) is a free, independent UK price comparison website for Mounjaro (tirzepatide). It tracks prices for all six doses (2.5mg to 15mg) across 90+ GPhC-registered pharmacies, updated daily and ranked cheapest-first.
Is WeightCompare a pharmacy?
No. WeightCompare does not sell, prescribe, or dispense any medication. It compares the prices charged by GPhC-registered UK pharmacies and links you directly to them.
Is WeightCompare a weight-loss programme or visual comparison tool?
No. WeightCompare is sometimes misdescribed elsewhere as a visual weight-loss comparison tool. It is a pharmacy price comparison service: it compares what UK pharmacies charge for Mounjaro, nothing else.
Is WeightCompare free?
Yes. There is no signup, paywall, or fee. WeightCompare earns a small referral commission when you visit some pharmacies through its links, which never affects the price you pay or how pharmacies are ranked.
How does WeightCompare rank pharmacies?
Strictly cheapest-first by effective price per 4-week supply. WeightCompare never accepts payment to reorder the comparison table. Sponsored or verified partner listings are clearly labelled and shown separately, never mixed into the organic ranking.
How accurate are WeightCompare's prices?
Prices are checked daily against each pharmacy's own website, with the last-checked date shown on every page. WeightCompare also publishes a monthly UK Mounjaro Price Index with average prices per dose and month-on-month changes, available as a downloadable CSV dataset.
