Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from the immunomodulatory peptide tuftsin. It is one of the most studied nootropic research peptides, investigated for its potential anxiolytic, cognitive, and neuroprotective activity without the sedative profile of traditional anxiolytics. Each Kynetide vial contains 10mg of Selank (CAS 129954-34-3), third-party HPLC tested to 99.8% purity with a full Certificate of Analysis and batch traceability.
Selank is most often investigated for anxiolytic and stress-modulating activity, with studies examining its influence on GABAergic signaling, serotonin balance, BDNF expression, and inflammatory and immune markers. It is frequently studied alongside Semax in nootropic and neuropeptide research and is typically administered intranasally in published animal and clinical models.
