Yes. Lamivudine is an approved medicine in Canada, classified as "Health Canada approved, prescription only". Approval covers its labeled indication and it is supplied on prescription, not over the counter. Products labeled "research use only" fall outside that approval and the label does not make human use lawful. On the evidence, 2 human studies are cited on its profile.

What this means
- 01
Health Canada has approved Lamivudine for at least one labeled indication, so a pharmaceutical-grade product exists in Canada and is dispensed on prescription.
- 02
Approval is indication-specific. Uses outside the label are a clinical decision for a prescriber, not something the approval itself authorizes.
- 03
Unlicensed online vials, including those labeled "research use only", are not the approved product and are not covered by the approval.
What Lamivudine is
A thirty year old HIV and hepatitis B drug repurposed on the hypothesis that LINE-1 retrotransposons drive the sterile inflammation of ageing. The human ageing evidence is one 12 person open-label pilot in Alzheimer disease with no control group.
Roughly 40 percent of the human genome is retrotransposon sequence. Most of it is silenced, and the silencing appears to fail with age.
Mechanism: A cytidine analogue that is phosphorylated intracellularly to lamivudine triphosphate, which is incorporated by reverse transcriptase and terminates the growing DNA chain because it lacks a 3 prime hydroxyl group. In HIV and hepatitis B that stops viral replication.
Regulatory history: FDA approved for HIV-1 infection in combination therapy and, as a separate lower-dose product, for chronic hepatitis B. Not approved for ageing, inflammation or neurodegeneration.
How Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for Lamivudine at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
