How This Works
Selank is a synthetic analog of the immunomodulatory peptide tuftsin, consisting of the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. In Russian clinical trials for anxiety disorders and neurasthenia, intranasal Selank produced anxiolytic effects comparable to benzodiazepines while also providing anti-asthenic (energy-boosting) benefits without sedative observations or dependence potential[1][2]. Preclinical studies in primates demonstrated that intranasal Selank eliminated fear and anxiety behaviors with long-term stabilizing effects on neurobehavior[4]. Rodent studies confirmed robust anxiolytic efficacy comparable to classical tranquilizers[5]. While most published human data utilized intranasal measurement (the original formulation), preparation has shown effectiveness in research settings with consistent absorption and ease of dose measurement[3]. A 14-day continuous course was well-tolerated and effective in human trials[2], and even high-dose applications have been explored for conditions such as attenuating opioid withdrawal symptoms in animal models[5].
