About Selank
Selank is a peptide analog derived from the endogenous tuftsin sequence and is frequently used in neuro-model systems involving GABAergic balance, cognitive signaling, and stress-adaptation pathways. Research explores its potential interactions with neuropeptide systems, neurotransmitter modulation, and anxiolytic-related pathways without sedative effects. Selank is a staple in studies examining cognitive processing, CNS communication, and stress-response regulation.

FAQs
What is Selank peptide?
Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. It is derived from the endogenous immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg) with an added Pro-Gly-Pro tripeptide extension that increases metabolic stability. Selank was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences and has been registered as a pharmaceutical product in Russia for anxiety and neurasthenic disorders.
What is Selank researched for?
Selank is studied for its anxiolytic, nootropic, and immunomodulatory effects in animal and cellular models. Research reports that Selank modulates the expression of brain-derived neurotrophic factor, interleukin-6, and multiple genes involved in GABAergic neurotransmission. Studies in rodent anxiety models, including the elevated plus maze and open field test, report anxiolytic-like effects comparable to benzodiazepines but without sedation or motor impairment.
How does Selank differ from Semax?
Both Selank and Semax share the Pro-Gly-Pro stabilizing extension and were developed at the same Russian research institute, but their parent peptides differ. Semax is derived from ACTH(4-7) and acts primarily on neurotrophic factor expression and cognitive function. Selank is derived from tuftsin, an immunostimulatory peptide, and has a stronger anxiolytic profile with additional immunomodulatory activity. Their distinct parent sequences produce different receptor interactions and downstream effects.
Does Selank affect the immune system in research models?
Yes. Selank retains immunomodulatory properties from its parent peptide tuftsin. Research shows that Selank increases phagocytic activity of neutrophils and monocytes, modulates cytokine expression profiles, and affects immunoglobulin levels in animal models. Gene expression studies in rat hippocampus report that Selank alters the transcription of genes involved in immune regulation, inflammation, and apoptosis alongside its effects on neurotransmitter-related gene expression.
Can I buy Selank peptide for research?
Limitless Peptides sells Selank as a lyophilized powder in a sealed 3mL glass ampule. The product is Janoshik verified for identity, potency, and purity. Selank is sold for research use only and is not approved for human consumption in the United States. The product page includes the manufacturer's certificate of analysis and a link to the independent Janoshik verification report.
