What Is Selank?

Selank 0.15% is an anxiolytic peptide with nootropic properties. The main effects inlcude antianxiety, antidepressant, and antiasthenic. By its structure, Selank is based on endogenous tetrapeptide Tuftsin which plays an important role in the immune system.

Selank usually goes in the form of nasal spray or drops.

The History Behind Selank Peptide

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.

To slow the breakdown of the peptide and prolong its effects, the inventors of Selank added glyproline to its structure. Numerous clinical trials confirmed the safety of this peptide, which was found to be void of dependence and to be non-toxic even in doses 200–500 times higher than therapeutic ones.

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. Read more about the producer in this blog post.
