PT-141 is the generic name for a peptide-based drug that was originally developed by the pharmaceutical company Palatin Technologies. It has gained attention in recent years as a potential treatment for sexual dysfunction and low libido. How does PT-141 work? PT-141 activates the melanocortin receptors in the brain, which are involved in regulating sexual arousal and desire. It stimulates the central nervous system, causing the release of various neurotransmitters and hormones that can enhance libido and sexual function in both men and women.

What conditions is PT-141 used for? PT-141 is being studied as a potential treatment for various forms of sexual dysfunction, including:
