Selank

Selank is a synthetic heptapeptide derived from the endogenous immunomodulatory peptide tuftsin and developed within broader neuroregulatory peptide research. It has been studied in cognitive research for its relationship to anxiolytic signaling, neurotransmitter modulation, stress-response pathways, and immune-neural interactions across preclinical and experimental models.

Selank is a synthetic heptapeptide derived from the endogenous immunomodulatory peptide tuftsin and developed within broader neuroregulatory peptide research. It has been studied in cognitive research for its relationship to anxiolytic signaling, neurotransmitter modulation, stress-response pathways, and immune-neural interactions across preclinical and experimental models. Its sequence modification improves peptide stability while preserving interaction with central regulatory signaling systems associated with tuftsin-derived compounds. Lyophilized powder, 3mL vial. Sold at 10mg per vial. For research use only.

Heptapeptide TKPRPGP. Russian-developed nootropic, tuftsin analog.
