First-month price by treatment
Prices are for the first 4-week supply at each treatment's usual starting dose, including any published new-customer offer. Introductory prices usually carry conditions; the ongoing price below is what treatment costs to continue.

Ongoing (repeat) price and multi-month cost
The repeat price at the starting dose, and the lowest 3-month and 6-month estimates at that dose. Real courses usually step up through doses, so treat multi-month totals as a floor, not a quote: our true cost guide explains the difference.

Coverage, confidence and limitations
- Coverage is the 20 UK online providers GLPInfo currently lists, not the whole UK market. A provider we do not list may exist and may be cheaper.
- Prices marked unconfirmed on our comparison pages are excluded from every statistic on this page.
- Delivery, consultation and fee terms differ by provider; per-record notes are in the data feed.
- These are private online prices. NHS access is a separate route with its own criteria.

Price index questions
How is the UK GLP-1 price index calculated?
Every figure on this page is computed live from the prices GLPInfo reads on each provider's own public pages, re-checked automatically every 12 hours. Lowest, median, average and highest are taken across providers with a published price at the treatment's usual starting dose. Providers without a confirmed price are excluded from the statistics rather than counted as zero. Full methodology.
Can I download the data?
Yes. The full dataset behind this index is free at /data/v1/prices.json and /data/v1/prices.csv, with sources, observation dates and GPhC verification links per record. Licence and citation instructions are at the data feed page.
Why is there no price history chart yet?
The index publishes only observations our checker has actually made. Historical trend sections will appear as monthly snapshots accumulate; we never reconstruct or estimate past prices we did not record.
