Selank is a short neuropeptide of seven amino acids, also indexed as TP-7. It sits in the neuropeptide research collection.
Vestrand supplies it as one production lot at a time, prepared for independent purity testing, with the certificate for each lot published to its verification page.
What is worth noting is how little there is to flag. Its record is clean — a single clear identity, nothing disputed, and a name that resolves the first time you search it — which is not something every peptide in this catalog can say. The chain is also notably proline-rich, three of its seven amino acids being proline.
