Its front half copies tuftsin, a small immune peptide the body cuts out of an antibody; the back half was added to stop enzymes destroying it. Russia has licensed it as nasal drops since 2009, and sells it there without a prescription. Nowhere else is it approved. Five human studies exist, covering roughly 250 people, none of them registered and none of them blinded. In April 2026 the US Food and Drug Administration recorded that it lacks important information about the safety of Selank in people.","updated":"2026-09-06","url":"https://mypep.app/peptides/selank"}
