What is Selank?
Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from the naturally occurring tuftsin peptide, with modifications designed to enhance enzymatic stability and bioavailability. It was developed in Russia and has been the subject of extensive preclinical behavioral and neurochemical research.
In preclinical research, Selank has been studied for its anxiolytic properties — its ability to modulate stress and anxiety-related behaviors in animal models. Research has examined its effects on serotonin and enkephalin systems, which are central to mood regulation and stress response. Unlike classical anxiolytics, Selank's mechanism does not appear to involve direct GABA receptor modulation, making it of interest in the study of alternative anxiolytic pathways.
Studies have also examined Selank's influence on BDNF expression, immune function via IL-6 modulation, and cognitive performance metrics in behavioral paradigms. Its exceptional enzymatic stability relative to natural tuftsin makes it a useful research tool for studying these pathways in vivo.

Frequently Asked Questions
What is Selank used for in research?
Selank is studied in preclinical research for its anxiolytic properties, BDNF upregulation, serotonin and enkephalin system modulation, and immune function via IL-6 pathway effects. It has been examined in behavioral studies related to stress response, cognitive performance, and neuroplasticity.
What purity is Pure Pharm's Selank?
Pure Pharm Selank is verified at 99.856% purity by third-party HPLC analysis. A Certificate of Analysis documenting identity, purity, and contaminant screening is available for every batch.
How is Selank verified for research use?
Each lot is independently tested by a USA laboratory using HPLC methodology. The full Certificate of Analysis is available on the product page and emailed with every order.
Does Pure Pharm provide a Certificate of Analysis for Selank?
Yes. A current COA is available for every batch of Selank we carry. You can access it directly from the product page or by clicking the COA button on this page.
What is the molecular structure of Selank?
Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP), derived from the naturally occurring tuftsin peptide with modifications for enhanced enzymatic stability. Its molecular formula is C₃₃H₅₇N₁₁O₉ with a molecular weight of 751.9 Da.
How does Selank compare to Semax in research?
Both Selank and Semax are synthetic heptapeptides studied for cognitive and neuroprotective effects, but they have distinct mechanisms. Selank is primarily studied for anxiolytic and stress-modulating properties via serotonin and enkephalin systems, while Semax is more associated with BDNF upregulation and dopaminergic modulation. They are sometimes studied in combination in cognitive research protocols.
Is Selank legal to buy for research purposes?
Yes. Selank is an unscheduled compound in the United States and is legally purchasable for legitimate laboratory and research purposes. Pure Pharm Peptides sells exclusively for research use only.
