Selank 0.15% is an anxiolytic peptide drug with nootropic properties usually sold as a nasal spray or drops. By its structure, Selank is based on endogenous tetrapeptide Tuftsin, which plays an important role in the immune system. To slow the breakdown of peptides and prolong its effects, the inventors of Selank added a Glyproline to its structure.

Tuftsin was found to have anxiolytic effects in 1995 and over the next decade, Russian scientists were focusing on developing a peptide drug that was able to have the most pronounced anxiolytic effects. This research, as well as clinical trials, lasted until 2009 when Selank was finally brought to market under the brand name Selank 0.15%It is produced in a GMP-compliant factory by Peptogen Inc.
