PT-141 is a peptide used for treating sexual dysfunction. It is a synthetic version of the peptide α-MSH (melanocyte-stimulating hormone). Specifically, PT-141 is a cyclic heptapeptide with the amino acid sequence Ac-Nle-cyclo(-Asp-His-D-Phe-Arg-Trp-Lys)-OH.
How does PT-141 work?
PT-141 works by activating melanocortin receptors throughout the body, particularly the MC1R and MC4R receptors in the brain. This leads to increased arousal, sexual desire, and sexual performance. Some key effects of PT-141 include:
Unlike Viagra which acts locally, PT-141 modulates the central nervous system to naturally promote sexual arousal.
What conditions is PT-141 used for?
PT-141 is used for treating sexual arousal disorder and erectile dysfunction. As it works through the central nervous system, it can help patients who don't respond to local-acting drugs get and maintain an erection.
Importantly, PT-141 also increases sexual desire, making it helpful for people with lack of libido - a common side effect from antidepressants.
How is PT-141 administered?
PT-141 comes in injection form and is injected under the skin. Effects start about 20 minutes after injection and peak around 60 minutes. A single injection lasts for several hours with maximum effect seen at doses around 20 mg.
Some doctors may provide a PT-141 nasal spray to avoid needles. However, injection tends to give the most consistent results.
If you are struggling with sexual dysfunction, I recommend contacting the hormone specialists at Renew Hormone Institute. They can assess your hormone levels and determine if PT-141 therapy is suitable for restoring your sexual vitality.
