Selank
Said to ease anxiety without making you drowsy — approved as a nasal spray in Russia, otherwise barely proven.
What it does in the body
Findings, each with its evidence level — animal data kept visibly apart from what's unproven in humans.
Said to ease anxiety without making you drowsy — approved as a nasal spray in Russia, otherwise barely proven.
ANIMAL MODELS ONLYWorks differently from classic sedatives (benzos) — the exact pathway is still unclear.
MECHANISM ONLYThe available studies come from Russia and haven't been independently confirmed.
UNPROVEN IN HUMANSMechanism of action
What Selank does in the body — step by step.
Selank is a synthetic heptapeptide, likewise developed at the Institute of Molecular Genetics of the Russian Academy of Sciences.
It is based on the sequence of the endogenous immunomodulator tuftsin (Thr-Lys-Pro-Arg) with a C-terminal Pro-Gly-Pro extension for enzymatic stabilisation.
In preclinical studies, anxiolytic effects without sedative properties have been described — compared with benzodiazepines, no GABA-A modulatory mechanism was demonstrated.
