FAQ
Common questions
How much does retatrutide cost in Canada?
Peptigo sells retatrutide in 10mg and 20mg vials, plus 30mg when it is in stock, priced in Canadian dollars. Current prices, with the sale applied, are in the table above, and the 20mg vial costs less per mg. Orders over $250 ship free.
Is retatrutide approved in Canada?
No. Retatrutide is an investigational compound and is not approved as a drug in Canada or anywhere else. Eli Lilly announced Phase 3 (TRIUMPH) results in 2026 and plans to submit it to the U.S. FDA in early 2027. Peptigo supplies it strictly for laboratory research, not for human or veterinary use. More in are peptides legal in 2026.
How fast does retatrutide ship?
In-stock orders ship from Canada the same business day, in cold-chain packaging. Shipping is free on orders over $250.
How is retatrutide different from semaglutide and tirzepatide?
Semaglutide acts on one receptor (GLP-1), tirzepatide on two (GLP-1 and GIP), and retatrutide on three (GLP-1, GIP and glucagon). We compare all three in semaglutide vs tirzepatide vs retatrutide, and Peptigo also carries Semaglutide and Tirzepatide.
Where can I read the research on retatrutide?
Our retatrutide research monograph summarizes the published studies, the trial status and the references.
