- Here's the honest answer: the difference is marketing and historical carryover. Nothing more. Peptide suppliers use 'MT-1' because it's shorter and customers searching for it assume it's distinct from 'melanotan-1,' which creates two product listings for the same molecule. Researchers new to melanocortin peptides waste time cross-referencing CAS numbers and amino-acid sequences to confirm they're identical when a single glance at the molecular formula (C78H111N21O19) would settle it. The confusion benefits no one except vendors who can charge different prices for differently labeled vials of the same compound.
- The regulatory name is afamelanotide. That's the only designation with legal meaning. If you're citing peptide use in publications, grants, or regulatory submissions, use 'afamelanotide' and include the CAS number. If you're ordering for research, specify the CAS number (75921-69-6) regardless of what the supplier calls it. Anything else is noise.
