Description
PT-141 (Bremelanotide) is the generic term for a research peptide being studied for its possible use in helping to improve sexual dysfunction in both men (erectile dysfunction or impotence) and women (sexual arousal disorder).
PT-141 was developed from the tanning peptide Melanotan 2, which is a synthetically produced variant of a peptide hormone naturally produced in the body that stimulates melanogenesis that is known as alpha-Melanocyte stimulating hormone. MSH, activates certain melanocortin receptors in the process of exerting its effects. Indeed, MSH also exerts potent influence over lipid metabolism, appetite, and sexual libido. Resultantly, PT-141 has been shown in studies to exhibit libido-enhancing effects by activating the melanocortin receptors MC1R and MC4R, but not skin tanning. Melanotan 1 and Melanotan 2 have been researched for their use in protecting against the harmful effects of ultraviolet radiation from sunlight due to their melanogenesis-stimulating properties.
PT-141 is a unique peptide in that it stimulates the MC-4R, which is known to produce sexual arousal in the central nervous system and influence sexual behavior. Studies in mice have shown that agonist binding to MC-4R causes sexual arousal and increased copulation in both males and females. Because PT-141 works via a different mechanism than drugs like Viagra, it is possible to treat sexual arousal disorders in both men and women that stem from causes other than reduced blood flow to the genitals.
Dosage:
Adults—1.75 milligrams (mg) injected under the skin at least 45 minutes before a sexual activity. Do not use more than one dose of this medicine within 24 hours. Do not use more than 8 doses per month.
