PT-141 is a peptide hormonal agent shared Melanotan II as they are commonly tested together as a sunless tanning option.

Sunless sun tanning, Melanotan II did stimulate the production of darkening facial colouring (melanogenesis) yet also triggered sex-related stimulation as well as spontaneous erections as unanticipated adverse effects in 9 out of the ten initial male volunteer guinea pig.

Bremelanotide (PT-141) is a peptide that’s developed by Palatin Technologies used mainly as a treatment for male ED (erectile dysfunction), FSD (female sexual dysfunction), reperfusion injury and hemorrhagic shock.

Because of this possibility, PT-141 is being researched as a prospective therapy for sex-related problems such as erectile disorders in males as well as sex-related arousal disorders in females, specifically Hypoactive libido problem (HSDD) as well as women sex-related interest/arousal condition (FSIAD).

PT-141 increases your sexual desire by activating the brain of the melanocortin four receptor, which normally regulates the metabolism, male erectile function and sexual behaviour. Its operating mechanism typically involves action in your central nervous system (CNS) instead of directly on the cardiovascular system.
