Melanocortin Agonists

A synthetic analog of α-melanocyte stimulating hormone that stimulates melanin production for skin darkening. Also produces sexual arousal effects. Not approved for human use but widely discussed in tanning communities.

A melanocortin receptor agonist FDA-approved for hypoactive sexual desire disorder (HSDD) in premenopausal women. Works through central nervous system pathways rather than vascular mechanisms.
