Health Canada's April 2026 peptide advisory, explained

On 9 April 2026, Health Canada published a public advisory about peptide products sold online without its authorization. It says peptides are generally regulated as prescription drugs in Canada, that research-use labels do not make a product legal, and it lists examples of products it has seized. A Canadian online seller of peptides later became subject to the injunction Health Canada described in its 29 July 2026 statement.

What the advisory is and who published it

Health Canada is the federal department responsible for drugs and health products in Canada. It published this advisory on 9 April 2026 on its Recalls and safety alerts website, under the title:

"Think twice before injecting peptides bought online: unauthorized products can seriously harm you"

Health Canada public advisory, 9 Apr 2026: "Think twice before injecting peptides bought online: unauthorized products can seriously harm you", retrieved 4 October 2026.

A public advisory is a warning notice written for the general public. This page goes through its six main lines one at a time, quoting each in full and then saying in plain words what it says. It does not add to what Health Canada wrote.

Peptides are generally regulated as prescription drugs

"In Canada, peptides are generally regulated as prescription drugs. Authorized peptide drugs should only be used under the care of a licensed healthcare professional, such as a doctor, to treat specific conditions."

Health Canada public advisory, 9 Apr 2026: "Think twice before injecting peptides bought online: unauthorized products can seriously harm you", retrieved 4 October 2026.

This is Health Canada's starting point: it places peptides under the rules for prescription drugs. Note the word "generally". The advisory states a general position rather than giving a full list, and the second sentence describes how Health Canada expects authorized peptide drugs to be handled, through a licensed professional.

Unauthorized products are illegal and have not been assessed

"Unauthorized drug products are illegal in Canada and have not been assessed for safety, efficacy, and quality by Health Canada. They have not been demonstrated, through scientific trials, to provide the health benefits that they claim."

Health Canada public advisory, 9 Apr 2026: "Think twice before injecting peptides bought online: unauthorized products can seriously harm you", retrieved 4 October 2026.

Health Canada says a drug product it has not authorized is illegal in Canada. It also says such products have not gone through its review, and that any health benefits claimed for them have not been shown in scientific trials.

Research-use labels do not change the rules

"Health Canada continues to identify products marketed as “For Research Use Only – Not for Human Consumption.” This type of labelling does not make these products legal or exempt from regulatory requirements. Canadians are advised not to buy or use products labelled in this way."

Health Canada public advisory, 9 Apr 2026: "Think twice before injecting peptides bought online: unauthorized products can seriously harm you", retrieved 4 October 2026.

Many peptide products online carry a label saying they are for research and not for people. Health Canada says this label does not make a product legal and does not exempt it from the rules. It also advises Canadians not to buy or use products labelled this way.

Seizures and work with the border agency

"Health Canada has seized several unauthorized injectable peptide drugs and is working with the Canada Border Services Agency to stop unauthorized shipments from entering the country."

Health Canada public advisory, 9 Apr 2026: "Think twice before injecting peptides bought online: unauthorized products can seriously harm you", retrieved 4 October 2026.

Health Canada says it has already seized products of this kind and is working with the Canada Border Services Agency on shipments it considers unauthorized. The advisory uses the word "several" and does not give a number.

The products Health Canada names

"The following products are examples of unauthorized injectable peptide drugs seized by Health Canada. Please note that many other unauthorized peptide drugs exist and should all be avoided:"

"BPC-157 CJC-1295 DSIP Epitalon GHK-Cu HCG Ipamorelin KPV Melanotan I and II MOTS-C NAD+ SS-31 TB-500 Retatrutide"

Health Canada public advisory, 9 Apr 2026: "Think twice before injecting peptides bought online: unauthorized products can seriously harm you", retrieved 4 October 2026.

Health Canada gives these names as examples of products it has seized. It says many others exist, so a name missing from this list has not been cleared by its absence. Being named here is also not the same thing as appearing on the Prescription Drug List. It means Health Canada seized unauthorized products of that kind.

How to check a product

"Check the label before you buy. Authorized prescription drugs in Canada have an eight-digit Drug Identification Number (DIN). You can also check whether a drug has been authorized for sale by searching Health Canada's Drug Product Database."

Health Canada public advisory, 9 Apr 2026: "Think twice before injecting peptides bought online: unauthorized products can seriously harm you", retrieved 4 October 2026.

"Search the Drug Product Database (DPD) to find drugs authorized for sale by Health Canada."

Health Canada: Drug Product Database, retrieved 4 October 2026.

The advisory gives two checks. First, look on the label for a Drug Identification Number, or DIN, which is eight digits long. Second, search Health Canada's Drug Product Database, a free public search tool on the Government of Canada website, to see whether the drug is listed as authorized for sale.

What came after: the court order

Later, after a May 2026 recall of two peptide powders (see the May 2026 peptide powder recall), came the injunction Health Canada described in its 29 July 2026 statement: a permanent court order against a Canadian online seller of peptide products. The statement repeats Health Canada's position:

"In Canada, injectable peptides are regulated as prescription drugs and must be authorized by Health Canada before they can be sold."

Health Canada statement, 29 Jul 2026: permanent injunction against a Canadian seller, retrieved 4 October 2026.

It also describes how far the order reaches:

"It also cannot advertise or assist others in advertising these products, including through any website or social media platform accessible with a Canadian Internet Protocol (IP) address."

Health Canada statement, 29 Jul 2026: permanent injunction against a Canadian seller, retrieved 4 October 2026.

A permanent injunction is a court order meant to last, rather than a temporary one. Health Canada's statement says this order covers advertising as well as selling, including on websites and social media that can be reached from a Canadian IP address. An IP address is the number that identifies an internet connection.

What this means for you

Put simply, the April 2026 advisory sets out four things. Health Canada generally regards peptides as prescription drugs. It says products it has not authorized are illegal. It says research-use labels do not change that. And it names examples of products it has seized. The injunction Health Canada described in its 29 July 2026 statement shows those rules being applied to a seller, including its online advertising. Health Canada's July statement puts it this way:

"Selling unauthorized prescription drugs or making false or misleading claims to prevent, treat or cure illnesses is illegal in Canada."

To see whether a specific drug is authorized, the DIN and the Drug Product Database, described above, are the checks Health Canada points to. For how the wider rules fit together, see are peptides legal in Canada?.
