Selank is a synthetic peptide derived from a fragment of tuftsin, a naturally occurring immune peptide. It is studied in neurological research and supplied for research use only.
What Selank is
Selank is based on a short fragment of tuftsin, modified for stability. Like Semax, it is classed among neuropeptides studied for activity in the nervous system.

How it is studied
In the laboratory, Selank is studied in neurological research, frequently alongside Semax. As a research peptide, it is a study tool and is not approved or intended for human use.
