Bremelanotide

A melanocortin receptor agonist used to boost sexual desire, primarily for premenopausal women with hypoactive sexual desire disorder. It’s typically taken as a subcutaneous injection about 45–60 minutes before sexual activity, working through brain pathways involved in desire rather than as a direct hormone replacement. The main benefit is improved libido and sexual interest, with caution advised in people with a personal or family history of melanoma.
