Are peptides legal in Canada?
It depends on the product. Peptides that Health Canada has authorized, like insulin, semaglutide and tirzepatide, are legal prescription drugs. Unauthorized peptides, including ones labelled "research use only", are illegal to sell, advertise or distribute.
How Health Canada classifies peptides
Health Canada says a peptide product can be a drug (Food and Drug Regulations) or a natural health product (Natural Health Products Regulations), depending on what it's used for, what it's made of and how it's taken. Injectable peptides are always classified as drugs, and injectable products cannot be natural health products.
Authorized products have an 8-digit DIN (drug identification number) or NPN (natural product number). Unauthorized peptides have neither, and haven't been assessed for safety, efficacy and quality.
"Research use only" labels don't make it legal
Health Canada says a research-use label "does not make a product legal to import or sell in Canada", and advises consumers not to buy or use products labelled "For Research Use Only – Not for Human Consumption".
Which peptides has Health Canada named?
Its April 9, 2026 advisory lists these as examples of unauthorized injectable peptides it has seized: BPC-157, CJC-1295, DSIP, Epitalon, GHK-Cu, HCG, Ipamorelin, KPV, Melanotan I and II, MOTS-C, SS-31, TB-500 and Retatrutide. It says many others exist.
Enforcement
Health Canada says it takes action against people and businesses that sell, advertise, promote or distribute unauthorized peptides. Actions include recalls, seizures, stop-sale requests, entry warrants, permanent court injunctions and ministerial orders. It works with the Canada Border Services Agency, and imported shipments may be refused entry, detained or seized.
On June 11, 2026, the Superior Court of Québec granted Health Canada a permanent injunction against online seller Canlab Research, barring it from selling or advertising unauthorized injectable peptides, including through any website or social media accessible from a Canadian IP address.
What about compounding?
Compounding by pharmacists generally falls under provincial rules, but Health Canada says it must not be used to get around federal drug review, and practitioners must not advertise compounded products to the public. CBC News reported in July 2026 that BPC-157 was being compounded as an oral product under natural health product rules, which experts criticized; see our BPC-157 page.
What about personal use?
Health Canada's materials focus on selling, advertising and importing. We did not find a Health Canada page stating a specific penalty for a person who uses an unauthorized peptide. Its safety advice is clear, though: don't buy or use them, buy prescription drugs only from licensed pharmacies, and check for a DIN.
Clinical trials are the legal route to unauthorized peptides
Health Canada says people may access unauthorized peptides only if enrolled in an approved clinical trial and followed under the trial protocol.
