Selank
Selank is a synthetic heptapeptide tuftsin analog studied in rodent anxiety and GABA-binding models, and the research catalog lists it at https://onesourcepeptides.com/product/selank.
Papers describe Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) as a stabilized tuftsin-derived heptapeptide. Volkova et al., Protein and Peptide Letters, 2018 (PMID 30255741) report that Selank acts as a positive allosteric modulator of [³H]GABA binding in membrane preparations, placing the peptide in a clear GABA-receptor pharmacology frame.
Semenova et al., Behavioural Neurology, 2017 (PMID 28280289) measure anxiety-related behavior in rats under unpredictable chronic mild stress with the elevated plus maze, including Selank alone and with diazepam. Kolik et al., Bulletin of Experimental Biology and Medicine, 2014 (PMID 24913576) examine Selank in a rat alcohol-withdrawal model with the same maze and social-interaction readouts. Slominsky et al., Doklady Biological Sciences, 2017 (PMID 28702721) report Selank effects on anxiety-like behavior in a 6-OHDA rat model alongside Semax.
Lot identity and purity belong on the certificate of analysis for the vial in hand—see Are research peptides third-party tested?. Selank on the catalog is laboratory research supply only. This note is not dosing, reconstitution, or human-use guidance.
