Melanotan II is a synthetic analog of the alpha-melanocyte-stimulating hormone (α-MSH), designed to stimulate melanin production for enhanced tanning and pigmentation. Known for its dual effects on skin tone and sexual function, Melanotan II is widely used in cosmetic and performance protocols to promote a sun-kissed appearance and boost libido.
Melanotan II binds to melanocortin receptors (primarily MC1R and MC4R), triggering:
 
Increased melanin synthesis in skin cells
Enhanced pigmentation without UV exposure
Activation of libido and sexual arousal pathways
Skin Tanning: Promotes gradual, natural-looking pigmentation
UV Protection: May reduce sunburn risk by increasing melanin density
Libido Enhancement: Known to stimulate sexual desire and performance
Body Composition Support: Some users report mild appetite suppression
