Melanotan II nasal spray: a possible risk factor for oral mucosal malignant melanoma?

Editor's note

This single case report raises a possible association between Melanotan II nasal spray use and oral mucosal malignant melanoma in a young woman.

It is directly about the peptide and adds to documented safety concerns around unregulated use.
