Peptides and Canadian law: how Health Canada regulates drugs, and where research-use material sits

This page describes the regulatory framework. It is not legal advice, it does not tell anyone what they may personally import or possess, and it does not predict what any border officer or regulator will decide in a particular case. Those are questions for a lawyer or for Health Canada; a supplier is the wrong source. What follows is the well-established part, with the unsettled parts marked as unsettled.

The statute, and why "drug" is defined by purpose

Drugs in Canada are regulated federally under the Food and Drugs Act and the regulations made under it, principally the Food and Drug Regulations.

The most important feature of the framework is that the Act's definition of a drug does not turn only on chemistry. It captures substances manufactured, sold or represented for use in the diagnosis, treatment, mitigation or prevention of a disease, disorder or abnormal physical state, and for restoring, correcting or modifying organic functions. Representation is part of the definition: the same powder can fall inside or outside the regime depending on what is claimed for it. Which is why claims about what a compound does for a person are not a marketing question in this field, they are a classification question.

Two prohibitions in the same Act are worth knowing by name. Section 3 restricts advertising a drug to the general public as a treatment, preventative or cure for the diseases listed in the Act's Schedule A. Section 9 prohibits labelling, selling or advertising a drug in a manner that is false, misleading or deceptive, or likely to create an erroneous impression about its character, value, composition or safety.

Market authorisation: DIN, NOC and the Drug Product Database

Before a drug can be sold for human use in Canada it needs authorisation. For a product containing a new active ingredient, that means a New Drug Submission reviewed by Health Canada and, if the review succeeds, a Notice of Compliance (an NOC). Authorised products carry a Drug Identification Number — a DIN — identifying the specific product: that manufacturer, formulation, strength, dosage form and set of approved uses.

The authorisation attaches to the product, not the molecule, and this is what most discussion of research peptides gets wrong. An approval is a finding that one manufacturer's preparation, made under an inspected licence to a filed specification, has evidence supporting particular uses in particular patients. It does not travel to a different preparation of the same chemical. Separately, Health Canada maintains a Prescription Drug List; an ingredient on it requires a prescription when sold as a drug.

Natural health products run a parallel track under the Natural Health Products Regulations, with an NPN rather than a DIN; absence from both databases means a substance is authorised under neither. What is authorised is public record, and worth checking rather than taking from a seller. Health Canada publishes the Drug Product Database, searchable by medicinal ingredient, and a portal for drugs and health products.

What "research use only" means, and what it does not

Selling a substance as a laboratory chemical for research is a different activity from selling an approved medicine. Research reagents are not reviewed by Health Canada for safety or efficacy, not manufactured under a drug establishment licence, not dispensed, and carry no authorised uses. Three consequences follow.

Research-use-only material is not authorised for human use. That is not a disclaimer attached to make a sale possible; it describes the material's actual position. Nobody has reviewed it for that, and no authorisation exists.

"Research use only" is not a licence or an exemption. It states what the material is supplied for. It creates no category outside the Food and Drugs Act, and it does not protect a seller who makes therapeutic claims — because, per the definition above, making those claims is part of what turns a substance into a drug.

Research on humans has its own regime entirely. Administering an unauthorised drug to people in Canada for research requires an authorised clinical trial under Division 5 of the Food and Drug Regulations, with research ethics board approval. Animal work runs through institutional animal care committees to Canadian Council on Animal Care standards. Buying a research chemical satisfies neither.

Three positions a compound can occupy

Compounds in this section do not share one status, and collapsing them is where most confusion starts.

Worked examples. Tesamorelin sits in the first row: authorised in Canada and the United States as a specific licensed product, for one indication in one patient population — and research-grade tesamorelin is not that product, as the certificate-of-analysis guide sets out. Tirzepatide is also the medicinal ingredient of an authorised prescription product here; the Drug Product Database is where to confirm which products and indications, rather than any supplier's page. Semax and Selank are registered medicines in Russia and not authorised in Canada, which puts them in the second row. Retatrutide is investigational and approved by no major regulator, and BPC-157, TB-500, KPV and thymosin alpha-1 are in the third row: not approved by Health Canada, the FDA or the EMA for any indication.

Anti-doping rules are separate from drug law. Several of these compounds appear on the World Anti-Doping Agency's prohibited list, which binds competitors through sport governing bodies rather than through the Act.

What is genuinely unsettled

Some questions here have no clean public answer, and it is more useful to say so than to invent one. How enforcement discretion is exercised against individuals, as opposed to commercial sellers, is not published in a form supporting any general statement. What happens to a particular shipment at a particular crossing depends on facts specific to it and on officer discretion. Whether a substance can be authorised as a natural health product, or is restricted to the drug framework, is a determination Health Canada makes case by case.

Anyone whose position depends on one of those answers should get it from a lawyer or from Health Canada, in writing, about their own facts. This page cannot answer it, and nor can anyone selling the material.

For the chemistry behind the compound names, see peptides explained and the glossary. Everything supplied here, BPC-157 and tesamorelin included, is for laboratory research use only. Nothing here is medical, dosing, or therapeutic guidance.

Common questions

Is it legal to sell research peptides in Canada? Material can be supplied as a laboratory chemical for research use, which is what is done here: not authorised for human use, not sold for human use, no therapeutic claim made for it. Whether a particular sale is lawful turns on what is claimed and what it is sold for — the point the Act's definition of a drug rests on.

A compound is approved in the United States. Does that make it legal here? No. Authorisation is national. An FDA-approved product has no Canadian authorisation unless Health Canada has granted one, and even then the approval belongs to that licensed product rather than to the molecule.

Can you tell me whether I can import this for myself? No, and be sceptical of any supplier who does. Personal importation involves the Act, its regulations and customs administration, and an individual's position depends on their own circumstances. Ask a lawyer or Health Canada.

How do I check a compound's status myself? Search the medicinal ingredient in the Drug Product Database. If no authorised product appears, no drug with that ingredient is authorised for sale in Canada. The Act is published in full on the Justice Laws website, and reading the definition of "drug" in section 2 is a better use of ten minutes than any supplier's summary of it, including this one.

All products sold by NovaEvum are for research and laboratory use only. They are not intended for human or animal consumption, diagnosis, treatment, cure, or prevention of any disease.
