What it is

Selank is a synthetic peptide based on the immunomodulatory peptide tuftsin, developed in Russia as an anxiolytic/nootropic.

Proposed mechanism

It is reported to modulate GABAergic and monoamine systems and BDNF, and to influence enkephalin metabolism, producing anxiolytic effects in animal models.¹

State of the evidence

Russian clinical use; limited independent trials; RUO elsewhere.

Regulatory & status

Approved in Russia; RUO in the US/EU.
