How does Selank work for anxiety and cognitive function?

Selank is a synthetic analog of the immunopeptide tuftsin developed at the Russian Academy of Sciences. Its anxiolytic effects appear to stem from allosteric modulation of GABA-A receptors, producing calming effects similar to benzodiazepines but without the associated risks of tolerance or dependence. Research suggests Selank also supports cognitive function through BDNF upregulation, enhanced synaptic plasticity, and protection of enkephalins from enzymatic degradation, though international validation remains limited.
