What is Selank?
Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. It extends the naturally occurring tetrapeptide tuftsin with a Pro-Gly-Pro segment, creating a distinct laboratory material for controlled neuropeptide research.
Experimental literature examines GABAergic and serotonergic markers, BDNF-related expression, cytokine signalling, and neuroimmune endpoints. Anxiolytic-related observations refer only to measurements in laboratory and animal models; they do not represent anxiety treatment, a calming benefit, medical advice, or a human-use outcome.
This listing covers lyophilized vial material. The pre-formulated research solution is listed separately as Selank nasal spray.
Selank COA and batch verification
A Janoshik Analytical report dated June 2026 is on file for Selank 10 mg vial material. Each vial carries a batch identifier researchers can use to confirm which documentation corresponds to the material received. The transparency page explains the identity, purity, and documentation framework behind the report.

Selank research questions
+What is Selank?
Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from the naturally occurring tetrapeptide tuftsin. It is supplied strictly as lyophilized laboratory research material — not for human or veterinary use.
+What is Selank studied for in laboratory research?
Published experimental work examines GABAergic and serotonergic markers, BDNF-related expression, cytokine signalling, and neuroimmune endpoints. Anxiolytic-related measurements are recorded only as laboratory or animal-model endpoints; no anxiety-treatment, medical, or human-use outcome is described or implied.
+How is the Selank vial format different from Selank nasal spray?
The vial format is supplied as sealed lyophilized powder, while the nasal spray is supplied as a pre-formulated research solution. The two formats have different handling and documentation requirements and are listed separately.
+Is a Selank COA on file?
Yes. A Janoshik Analytical report dated June 2026 is on file for Selank 10 mg vial material. Researchers should use the batch identifier on the material received to confirm the corresponding documentation through the public COA lookup.
+What purity specification applies to Selank?
The listed purity specification is ≥99%. A general specification should not be treated as a batch result; use the batch identifier to locate the documentation corresponding to the material received.
+What vial sizes are available?
Selank is supplied as lyophilized research material in sealed 5 mg and 10 mg vials. Current formats and offers are shown on this page.
+How should sealed Selank be stored?
Keep the sealed lyophilized vial refrigerated, dry, and protected from light, following its batch documentation, and avoid repeated freeze-thaw cycles. The material is intended strictly for controlled laboratory research.
