PT-141 (Bremelanotide) for Libido

PT-141, also known by its prescription name Bremelanotide, is a synthetic peptide developed from Melanotan II. It is unique among sexual health medications because it works directly on the central nervous system to increase libido, rather than on the cardiovascular system to improve blood flow. It activates melanocortin receptors in the brain that are associated with sexual arousal. This makes it an effective treatment for both men and women suffering from low sexual desire. While sexual health is a key component of overall quality of life, its link to biological age is primarily through its connection to a healthy endocrine and nervous system. A healthy libido is often a marker of good hormonal balance and vitality, which are characteristics of a lower biological age. PT-141 is administered via subcutaneous injection or nasal spray and provides a powerful tool for addressing the central, rather than just the peripheral, aspects of sexual function.
