Direct answer
No. ARD-101 is not an approved medicine in Canada. Its legal category is "Not approved". Nothing that contains it is allowed for any use in people. Vials labeled "for research use only" get no exception: that label does not make them legal to use in people. On the evidence, 1 completed human trial is cited on its profile.

What this means
- 01
No product containing ARD-101 is approved by Health Canada for any use in Canada. So nothing on sale is allowed for use in people.
- 02
"Research use only" is a label sellers put on. It is not a legal category that allows use in people, and it does not get a product out of medicines law.
- 03
Importing it, supplying it or promoting it for use in people can fall under medicines law in Canada. This page is general information, not legal advice.
What ARD-101 is
It made adults less hungry by switching on bitter taste receptors in the gut. Both of its final-stage studies, in a rare hunger disorder called Prader-Willi syndrome, were stopped.
Bitter taste receptors are not just on your tongue. They line your gut too.
How it works: ARD-101 is a pill that switches on bitter taste receptors. It is built to stay inside the gut and not get absorbed into the blood.
Approval history: Never approved. Both final-stage studies in Prader-Willi syndrome, a rare genetic condition, are listed as TERMINATED (stopped) on ClinicalTrials.gov.
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 ARD-101 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.
ARD-101 in sport and the military
Whether ARD-101 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 ARD-101 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.

- Operation Supplement Safety (US service members)
