Direct answer
No. Selank is not an approved medicine in the United States. Its legal category is "Not approved; research use only". 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, 3 completed human trials are cited on its profile.

What this means
- 01
No product containing Selank is approved by FDA for any use in the United States. 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 States. This page is general information, not legal advice.
What Selank is
A lab-made peptide from Russia, used for anxiety. It is said to calm people without making them sleepy.
Selank is a lab-made copy of tuftsin, a small peptide from the immune system. It was made in Russia to treat anxiety and is approved there.
How it works: It works on GABA, the brain's main calming chemical, and on mood chemicals like serotonin. It slows the breakdown of enkephalins, the body's own calming and pain-relief chemicals.
Approval history: Not FDA-approved (approved in Russia)
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 Selank 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.
Selank in sport and the military
Whether Selank 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 Selank 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.
