What It Is
Melanotan II (MT-II) is a synthetic analog of alpha-MSH that activates multiple melanocortin receptors including MC1R, MC3R, MC4R, and MC5R. It is more potent and less selective than MT-I, producing stronger tanning effects alongside sexual function and appetite effects.
What It Does
MT-II stimulates melanin production for tanning and UV protection, increases sexual desire and arousal (through MC4R), reduces appetite, and has anti inflammatory effects.
How It Works
MT-II activates MC1R in melanocytes for tanning, MC3R and MC4R in the hypothalamus for sexual function and appetite regulation, and MC5R for various peripheral effects.
Who Benefits Most
People who want both tanning and sexual function support from a single compound. People who have used MT-I and want a stronger effect.
Cautions
May cause nausea, flushing, spontaneous erections, fatigue, or darkening of existing moles. Monitor skin lesions. Not recommended during pregnancy.
