What is on file, and how it is handled

Every figure below is transcribed from the paperwork for this compound.

What is Melanotan II?

Three changes separate it from native alpha-MSH: norleucine replaces methionine, D-phenylalanine replaces the L form, and a lactam bridge between the lysine side-chain amine and an aspartate carboxyl closes the molecule into a ring. Cyclising a linear peptide this way is a standard route to resisting enzymatic breakdown, and it is why this analogue is far more stable than the hormone it derives from.
