Is LOY-002 legal in the United States?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
No. LOY-002 is not approved for any medical use in the United States. Its legal category is "Investigational as an animal (veterinary) drug; not for human use". 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
LOY-002 is being tested in registered clinical trials (official studies in people). FDA has not approved it for sale in the United States.
- 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.

How FDA treats this kind of product
Approves prescription drugs, each for a named use. It also acts against unapproved products, including peptides sold online. Compounding pharmacies, which mix drugs to order, may make some compounds with a prescription. That only applies when the FDA puts the compound in a category of bulk ingredients it allows.
The legal category above is how The Longevity Archive reads U.S. Food and Drug Administration 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 States. 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.
