Research compound supplied in Australia by Pulse Biolabs for laboratory use. Available in 10mg.
Selank is built from tuftsin, a short piece of an antibody. Research asks what that sequence does to the brain's main calming signal.
Selank is a synthetic seven-amino-acid peptide: tuftsin, a fragment of the antibody immunoglobulin G, extended with a Pro-Gly-Pro tail to slow breakdown. It is studied for whether a peptide can influence GABA signalling, the brain's main inhibitory system, which most anxiety medicines act on. The evidence is laboratory binding and gene-expression work in rat tissue and cultured cells, plus small Russian clinical studies in patients with anxiety disorders whose designs limit interpretation.

2 published reports for Selank, listed by presentation and batch. Where a batch reference is shown, match it to the batch on the vial label; a report for an earlier batch is historical documentation and does not describe the batch currently supplied. Where no batch reference is published, the report cannot be matched to a vial and is historical documentation only. Each report describes the sample and the tests shown on it. A purity result does not by itself establish identity, quantity, sterility or endotoxin status unless those tests appear on the report, and a report for one batch does not describe another.
