First, very few dysplastic nevi actually go on to turn into melanomas, which makes the removal of all nevi unnecessary

Melatonin is a hormone tied to sleep, while the melanotan peptides act on pigment and melanocortin receptors

This conformational constraint simultaneously increases metabolic stability by reducing the accessible surface area for protease attack and shifts receptor subtype selectivity toward the centrally expressed MC3R and MC4R subtypes relative to the uncyclised linear peptide

Research has characterised PT-141 as a direct MT-II derivative produced by C-terminal amide hydrolysis , documenting preserved cyclic heptapeptide structure, maintained MC3R/MC4R pro-sexual activity, and reduced MC1R-mediated pigmentation activity relative to MT-II
