Both ends of the chain are chemically capped. The earliest trace found is an online shop page from 2015 announcing that change. The only peer-reviewed paper found on the exact molecule describes a laboratory test method and contains no biological data. No approval was found in any market checked, and Semax doses must not be carried over to it. In sport it is banned at all times.","updated":"2026-09-24","url":"https://mypep.app/peptides/n-acetyl-semax"}
