Synthetic α-MSH analog — activates melanocortin receptors (MC1R/MC4R) — research areas: melanogenesis, energy balance, sexual signaling.
Mechanism: α-MSH analog on melanocortin receptors (MC1R/MC4R); stimulates melanogenesis.
Evidence: Limited human data; mostly research and anecdotal use.
In context: Darkens moles/skin — watch for new or changing moles (melanoma caution); gray-market sources often mislabel it.
