MT-1, also known as afamelanotide, is a synthetic peptide of thirteen amino acids from the melanocortin family. It is catalogued in the melanocortin and dermal research collection.
It is offered as a single reference lot, prepared for independent analysis, and the certificate for the lot you receive is published to its verification page once testing wraps up.
It carries one genuinely unusual entry on its record: it is the only compound in the catalog with a documented colour — a white to off-white powder — and the only one stored cold at 2–8 °C rather than frozen. Those details come from a regulatory label for a finished product, and we say so plainly rather than dressing them up as bulk-material specifications.
