What the official sources say
Lilly's retatrutide FAQ, updated September 2026, says it is not available for public use and is available only to participants in Lilly's clinical trials. It does not announce an Irish launch date.
We checked the HPRA human-medicines XML list on 13 October 2026 for both retatrutide and LY3437943. Neither appeared. Lilly's TRIUMPH-1 listing identifies LY3437943 as retatrutide. This is a dated list check, rather than a guarantee that the status will stay the same.
Irish price and launch date
There is no confirmed approved Irish retail price in the sources checked. A price advertised by a research-peptide seller is not a price for an approved retatrutide medicine.
The sources checked do not confirm an Irish launch date. Lilly says public availability depends on clinical trials and regulatory approval. Trial news does not establish an Irish launch date.
What about research-peptide sellers?
Lilly warns that illicit products sold as retatrutide may contain unknown ingredients or contaminants. We do not list these sellers, their prices or instructions for using their products. Read the HPRA's warning about buying medicines online.
Retatrutide, orforglipron and the Wegovy pill
Retatrutide, orforglipron and the Wegovy pill are different products. Each has its own approval and availability status. Read our separately dated orforglipron (Foundayo) Ireland status and Wegovy pill Ireland guide.
