Selank is one of the best-known research peptides within neuro and cognition research. In this guide we explain, research-only, what Selank is, where it comes from and within which research themes it is studied — without any health or cognition claims.
Selank is a synthetic heptapeptide derived from the body's own peptide tuftsin, studied in relation to anxiety, stress and cognition research. It is not a medicine and is offered for research only, ≥99% pure with a COA per batch.
What is Selank?
Selank is a synthetic heptapeptide — a chain of seven amino acids — derived from the body's own immune peptide tuftsin. That origin makes it an interesting object of study at the intersection of neuroscience and immunology. New to peptides? First read what peptides are.
What is Selank studied for in research?
In research Selank is mainly associated with the anxiety and stress response and with aspects of cognition. It is a recurring object of study within neuropeptide research, which originally comes from the Russian scientific tradition. These descriptions come from preclinical research and are no proof of effect in humans.
Selank vs. Semax
Selank and Semax are often mentioned together, but have a different origin: Selank derives from tuftsin, Semax from a fragment of the hormone ACTH. Both are short synthetic peptides studied within neuro and cognition research. Read more about the counterpart in what is Semax, or see both in the category cognition & focus. Within the same research direction, DSIP and Epithalon are also studied.
How is Selank reconstituted?
Selank is supplied as a lyophilised powder and reconstituted in the lab with bacteriostatic water. Determine the right ratio with the reconstitution calculator, or read how to reconstitute peptides.
Purity and documentation
Reproducible neuro research requires material with verified purity and full traceability. Every batch of Selank at Peptide Lab is tested by Janoshik Analytical at ≥99% purity by HPLC and mass spectrometry, with a public certificate per lot number. Read more about our approach on the science page.
