Side-by-side reference comparisons of related research compounds and formats.
Selank and Semax share one design feature, a C-terminal Pro-Gly-Pro tail, and little else: Selank is built from the immunoglobulin fragment tuftsin, Semax from a fragment of adrenocorticotropic hormone. Most published work studies one compound or the other, so most of the two literatures cannot be compared at all. Five studies examined both within the same experiment, and those are the only sources supporting direct comparison. This guide sets out what has been compared, what has not, and what the certificates for the two products record.
