Is SRK-439 legal in Canada?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
No. SRK-439 is not approved for any medical use in Canada. Its legal category is "Investigational, not approved". The only legal way to get it is to join a registered clinical trial (an official study in people). A "research use only" label on vials sold online does not make them legal to use in people. On the evidence, no study in people is cited on its profile.

What this means
- 01
SRK-439 is being tested in registered clinical trials (official studies in people). Health Canada has not approved it for sale in Canada.
- 02
The only legal ways for a person to get it are to join a trial, or to use an official early-access program where one exists. There is no pharmacy product to prescribe.
- 03
Vials sold online "for research use only" are not trial supplies. That label does not make them legal to use in people.
What SRK-439 is
Scholar Rock's follow-up to apitegromab, built to be self-injected alongside GLP-1 drugs. First results in people are expected in the second half of 2026.
SRK-439 blocks the same inactive form of myostatin as apitegromab. Apitegromab is given through a drip for spinal muscular atrophy.
How it works: It is an antibody that stops myostatin from switching on.
Approval history: Investigational; in early safety studies
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 SRK-439 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.
SRK-439 in sport and the military
Whether SRK-439 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 SRK-439 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.
