PT-141, also known as bremelanotide, is a synthetic peptide that acts on melanocortin receptors in the central nervous system. It has been studied for its role in supporting sexual arousal and desire by influencing neural pathways related to libido rather than vascular mechanisms. Research has explored its use in both men and women experiencing reduced sexual interest.
Kisspeptin is a naturally occurring peptide that plays a central role in regulating the hypothalamic-pituitary-gonadal (HPG) axis. It stimulates the release of gonadotropin-releasing hormone (GnRH), which can influence testosterone and estrogen production. It has been studied for its potential impact on fertility, hormonal balance, and reproductive health.
DSIP is a neuropeptide associated with the regulation of sleep cycles and circadian rhythm. It has been researched for its potential role in promoting restorative sleep, supporting stress response, and influencing hormonal balance through its effects on the central nervous system.
Melanotan II is a melanocortin analog originally developed to stimulate melanin production. It has also been researched for its potential influence on sexual function, appetite, and energy regulation due to its interaction with melanocortin receptors in the brain.
