Selank

A synthetic anxiolytic/nootropic peptide derived from tuftsin.

Research peptideLimited

Identity

Class
Synthetic heptapeptide (tuftsin analog)
Source
Synthetic; based on the immunopeptide tuftsin
Receptor
No single established receptor; effects on GABA/serotonin and immune signaling proposed

Key properties

Molecular weight
751.9 Da

Approximate values for the native hormone. Engineered analogs are often deliberately larger and far longer-acting.

Mechanism

Selank is a synthetic heptapeptide based on the immune-active fragment tuftsin, developed (largely in Russia) as an anxiolytic and nootropic. Proposed effects touch GABAergic, serotonergic, and immune signaling, but well-controlled independent human evidence is limited.

Reference notes

  • Derived from tuftsin, an endogenous immunomodulatory peptide fragment.
  • Developed primarily outside large international trial programs; independent evidence is limited.
  • Mechanism is proposed across several systems rather than firmly established.
