A Canadian drug authorization appears as a Drug Identification Number in a database open to the public. Nothing without one has passed a review. On 9 April 2026 Health Canada stated that "Research Use Only" labelling does not make a product legal or exempt from regulatory requirements, and that is the reading this site works to.
Retatrutide is among the peptides named in a Health Canada public advisory about unauthorized injectable products sold online. That advisory concerns material sold for people to inject without authorization. Borealis Peptides supplies research material for in-vitro laboratory work and sells nothing for injection or for any use in a person, which is the distinction the advisory turns on.
