The form
Is it nose drops or a shot?
Ask whether the studies tested nose drops or injections.
The Russian maker’s Selank leaflet describes a nose-drop product.
Distinguish the product and its records
If an injection is offered, ask which studies tested Selank shots. Ask for the product’s name and maker, not just the name Selank.
A past medicine listing in Russia
Russia had listed Selank as an anxiety medicine on its official medicine list. As of September 2026, it was unclear whether that listing was still valid.
That history gives Selank no U.S. approval.
If someone refers to use in another country, ask which product they mean and when it was listed. Ask whether they mean nose drops or a shot.
The drug list shows raw powder
In September 2026, FDA’s drug directory listed Selank powder supplied as an ingredient, rather than a finished medicine.
Products listed in that directory have a number called a National Drug Code, shortened to NDC. The number does not mean FDA approved the product.
If an offer shows a drug code, ask whether it refers to raw powder or the finished shot. Ask who made the shot being offered.
Keep the product description
Write down whether the product is nose drops or a shot. Ask for the maker’s name and the studies about that product in writing. Keep those details with your questions.
