Is Goserelin legal in Canada?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Yes. Goserelin 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 (2 human records with no result or no dose given).

Legal category
Health Canada approved, prescription only
Health Canada authorisation and DIN status, from the Goserelin 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 Goserelin 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 Goserelin is
A prescription medicine, not a research peptide. It is an implant approved as Zoladex and used for decades for prostate cancer, hormone-driven breast cancer and endometriosis.
Goserelin is a GnRH drug approved as Zoladex and used for decades. It comes as a small implant placed under the skin that releases the drug over one to three months.
How it works: A steady signal on the GnRH receptor wears out the pituitary gland's response. That lowers LH, FSH, testosterone and oestrogen.
Approval history: FDA-approved (Zoladex)
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 Goserelin 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.
Goserelin in sport and the military
Whether Goserelin 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 Goserelin 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.
