Is Metreleptin legal in Canada?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Yes. Metreleptin is an approved medicine in Canada. Its legal category is "Health Canada approved, prescription only". The approval covers the use on its label. It is given out on prescription, not sold over the counter. Products labeled "research use only" are not covered by that approval, and that label does not make them legal to use in people. On the evidence, no completed trial in people is cited on its profile (1 human record with no result or no dose given).

Legal category
Health Canada approved, prescription only
Health Canada authorisation and DIN status, from the Metreleptin profile.
Reviewed Sep 2026. This is a legal category, not legal advice.
A "research use only" label on a vial does not make it legal to use on people.

What this means
- 01
Health Canada has approved Metreleptin for at least one use named on its label. So a proper pharmacy-grade product exists in Canada, and pharmacies hand it out on prescription.
- 02
Approval covers only the uses named on the label. Any other use is a prescriber's call. The approval itself does not cover it.
- 03
Unlicensed vials sold online, including those labeled "research use only", are not the approved product. The approval does not cover them.
What Metreleptin is
Life-changing in people who make almost no leptin, and useless for ordinary obesity. The clearest case on this site of a hormone that only works when you are short of it.
When leptin was found in 1994, a cure for obesity looked close. Here was the hormone that tells the brain how much fat you carry.
How it works: Metreleptin is a lab-made copy of human leptin, with one extra amino acid (methionine) added. Fat cells release leptin in line with how much fat you carry.
Approval history: FDA-approved as Myalept for problems caused by too little leptin in generalised lipodystrophy, a rare condition where the body has almost no fat. It carries a boxed warning, the FDA's strongest, for two risks. The body can make antibodies that block the drug, and it can raise the risk of T-cell lymphoma, a blood cancer. It is only supplied through a restricted program. Not approved for obesity or partial lipodystrophy.
How Health Canada treats this kind of product
Allows a drug to be sold by issuing a Notice of Compliance and a Drug Identification Number (DIN). A compound that is not allowed for sale cannot legally be sold for use in people. Bringing in prescription drugs for your own use is also limited.
The legal category above is how The Longevity Archive reads Health Canada, Health Products and Food Branch listings for Metreleptin on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.
Metreleptin in sport and the military
Whether Metreleptin is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in Canada. Before you compete or get tested, look up Metreleptin by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.

- Global DRO (check a named product)
