Kisspeptin-10 is a naturally occurring neuropeptide that acts as the master regulator of the hypothalamic-pituitary-gonadal (HPG) axis. It is the primary driver of GnRH (gonadotropin-releasing hormone) pulsatility, making it the upstream controller of testosterone, estrogen, and reproductive function.

Oxytocin is the brain's primary social and bonding neuropeptide — often called the 'love hormone' or 'cuddle chemical.' It modulates trust, empathy, pair bonding, sexual behavior, social memory, and maternal behavior. Beyond its social functions, oxytocin has documented effects on anxiety reduction, pain modulation, gut motility, sexual function, and metabolic regulation. Research applications include autism spectrum disorder, PTSD, social anxiety, and sexual dysfunction.

PT-141 (Bremelanotide) is the only FDA-approved melanocortin receptor agonist for the treatment of hypoactive sexual desire disorder (HSDD) in premenopausal women. Unlike PDE5 inhibitors, it acts centrally through the nervous system rather than the vascular system.
