No. LOY-002 is not an approved medicine in the United Kingdom. Its legal category is "Not licensed". 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, no study in people is cited on its profile.

What this means
- 01
No product containing LOY-002 is approved by MHRA for any use in the United Kingdom. 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 the United Kingdom. This page is general information, not legal advice.
What LOY-002 is
A daily pill for older dogs that could become the first drug the FDA approves to extend lifespan. The FDA accepted its safety and effectiveness sections in 2025 and 2026.
LOY-002 is a daily pill from Loyal for dogs aged ten and older. It is meant to fix the changes in how the body handles fuel that come with age.
How it works: Not made public. The company says it corrects changes in how the body handles fuel that come with age.
Approval history: On a conditional-approval path as an animal (veterinary) drug; not for humans
How MHRA treats this kind of product
Licenses medicines for sale in the UK. A compound without a licence to be sold (a marketing authorisation) is an unlicensed medicine. The law only lets it reach people through a prescriber, under the specials scheme (unlicensed medicines made for one patient's needs). It cannot be sold as a research product.
The legal category above is how The Longevity Archive reads Medicines and Healthcare products Regulatory Agency listings for LOY-002 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.
LOY-002 in sport and the military
Whether LOY-002 is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in the United Kingdom. Before you compete or get tested, look up LOY-002 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)
