Compounded GLP-1 in Canada: what Health Canada says.
Online ads for compounded or “research” semaglutide and tirzepatide target Canadians searching for cheaper GLP-1s. Health Canada's position is clear. This page quotes that position and links authorized alternatives. We don't sell anything.
Health Canada's warning
The April 2026 advisorysays unauthorized peptides bought online can seriously harm, and that “research use only” or “not for human consumption” labels give no legal exemption for sale for human use.
Verify any product's DIN in the Drug Product Database.
