Selank — 5 mg
Selank is a synthetic heptapeptide derived from tuftsin, an immunomodulatory peptide. Developed in Russia alongside Semax, it has been studied for its anxiolytic properties and effects on cognitive function.
Published Research
- Research published in Russian journals documented that Selank affects the expression of genes involved in GABAergic neurotransmission, which is associated with anxiety regulation.
- Studies have examined Selank's effects on anxiety-like behaviors in various animal models, with researchers noting modulation of stress-response pathways.
- Research has documented immunomodulatory properties, consistent with its derivation from the immunopeptide tuftsin.
- Clinical observations in Russia have examined Selank's effects on generalized anxiety and cognitive performance.
Mechanism of Action
Selank is proposed to modulate GABAergic neurotransmission and influence IL-6 expression. Research suggests involvement in stress adaptation and immune system regulation pathways.
