Melanocortin Research Peptide
Melanotan I is studied for how the body produces skin pigment (melanin) and shields skin from UV light. It is a lab-made analogue of the natural alpha-MSH hormone that mainly activates the MC1R receptor on pigment cells, which is why it appears in preclinical research on melanin production and photoprotection.
