PT-141, also known as bremelanotide, has emerged as a fascinating peptide in the realm of sexual dysfunction treatment research. This peptide, available in 2mg x 10 vials with a 99% purity level at Peptide Gurus, is strictly for research use only, in line with the regulations set by the FDA.
PT-141 works by binding primarily to the melanocortin 4 receptor (MC-4R) and MC-1R. Its unique mechanism of action sets it apart from traditional erectile dysfunction drugs like Viagra. Viagra mainly addresses sexual issues caused by poor blood flow to the genitals, while
PT-141 acts on the central nervous system to stimulate sexual arousal. This means it has the potential to treat sexual arousal disorders in both men and women that stem from various causes, not just blood flow problems.
In clinical trials, PT-141 has shown promising results. In a study involving men with erectile dysfunction who did not respond to sildenafil (Viagra), approximately one – third experienced adequate erections for sexual intercourse when administered PT-141 via nasal spray. There was also a clear dose – dependent response, indicating its effectiveness in certain cases.
For women, PT-141 was investigated in phase IIb human clinical trials for the treatment of female hypoactive sexual desire disorder (HSDD). Although it increased the number of satisfying sexual events per month and decreased female sexual distress scores significantly, without substantial side effects, it was pulled from clinical trials before approval. This was mainly due to a lack of established endpoints for female sexual dysfunction trials and socio – cultural biases against women’s sexual health. However, in 2017, Phase II Reconnect trials were launched using subcutaneous injections of PT-141 for female sexual dysfunction (FSD). The new version, Rekynda, may soon be available in the United States, and it could potentially be used off – label to treat both male and female sexual dysfunction.

It’s important to note that according to the FDA’s latest guidelines, PT-141 is not approved for human consumption or treatment without proper authorization. The FDA’s main concern is to ensure public safety. Unapproved use of PT-141 can lead to unpredictable health consequences. Research involving PT-141 must be conducted in a well – regulated environment, following strict ethical and scientific standards. Researchers need to have the appropriate licenses, facilities, and knowledge to work with this peptide.
Beyond sexual dysfunction, PT-141 has also shown potential in other areas of research. For example, it was investigated as a treatment for acute hemorrhage in 2009. By binding to MC-1R and MC-4R, it reduces ischemia and protects tissues against inadequate blood supply during hemorrhagic shock. It has also shown anti – fungal and anti – inflammatory properties in a rat model of a specific fungal infection, and the MC-1R it binds to is involved in DNA repair pathways, making it relevant in cancer research.
In conclusion, while PT-141 holds great promise for the treatment of sexual dysfunction, it is crucial to respect the FDA’s regulations and conduct research in a proper manner. This ensures that the potential benefits of this peptide can be fully explored without compromising public health.
Common Questions and Answers:
- Can I buy PT-141 over – the – counter to treat my sexual dysfunction?
- No, PT-141 is only available for research purposes. It is not approved for over – the – counter sale or self – treatment. Buying and using it without proper authorization is illegal and can be dangerous to your health.
- What are the possible side effects of PT-141?
- Although it showed minimal side effects in some trials, potential side effects may include nausea, flushing, and changes in blood pressure. However, more research is needed to fully understand all possible side effects, especially with long – term use.
- If I’m a researcher, what do I need to start working with PT-141?
- You need to be a licensed researcher. You should also have access to proper laboratory facilities and follow strict ethical and scientific protocols. Additionally, you must comply with all FDA regulations regarding peptide research.
