Selank

Selank is an investigational synthetic heptapeptide developed as a nasal spray or injectable candidate. It is a synthetic analogue of the human immunomodulatory peptide tuftsin. It is being researched for potential anxiolytic (anti-anxiety), nootropic (cognitive enhancement, focus, memory), and neuroprotective effects, as well as possible immunomodulatory and stress-resilience properties. As of 2026, Selank remains unapproved by the Therapeutic Goods Administration (TGA) for general use and is primarily available for research purposes.
