What is PT-141?

PT-141 is a libido peptide. It is used to treat sexual dysfunction in women as well as hemorrhagic shock, and reperfusion injury. It was available in a nasal spray until it was discontinued in 2008 after health concerns. It is now available as a substance to use for injection.

PT-141 came from the Melanotan testing that occurred in scientific studies. They noticed what while Melanotan and Melanotan II were successful in tanning skin without sunlight, the side effects were sexual arousal in men and women with erection benefits for men who had erectile dysfunction. In a third clinical trial, PT-141 was shown to enact the lordosis behavior in animal test subjects. It directly changes the chemicals in the brain that turn on during arousal without passing through the blood stream.

Applications :

PT-141 functions by activating the melanocortin 1 receptor and MC4R namely. Bremelanotide originally was tested for nasal spray delivery but was discontinued after concerns about side effects. Bremelanotide PT141, as Melanotan II, may cause spontaneous arousal enhancing effect. Unlike other supplements, pt 141 results do not act on the vascular body, but directly increases desires through the nervous system.

PT-141 or Bremelanotide is the generic term for a 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 has a similar structure to Melanotan-II and is a synthetic analogue of alpha-Melanocyte stimulating hormone (α-MSH). Alpha-MSH is an endogenous peptide that has potential influence over lipid metabolism, appetite, and sexual libido. PT-141 is a potential remedy for the treatment of sexual dysfunction and studies have shown that PT-141 does not act on the vascular system like former compounds, but allegedly works by activating melanocortin receptors in the brain, therefore helping increase ones sexual stimulation.

How Does PT-141 Work?

PT-141 increases your sexual desire by activating the brain of the melanocortin 4 receptor, which normally regulates the metabolism, male erectile function and sexual behaviour. Its operating mechanism typically involves an action in your central nervous system (CNS) instead of directly on the cardiovascular system.

PT-141 dose:

PT-141 comes in 10mg vials. As a lifestyle peptide, the 10mg product is a lot to consume and may offer up to 20 doses when dosing light. The PT-141 peptide reconstituted with bacteriostatic water remains potent in the fridge for months.

PT141 Effects:

Bremelanotide (PT-141) was developed from Melanotan 2 (MT-II).PT-141 is a metabolite of MT-II that lacks the C-terminal amide function-stripping away tanning properties.

PT-141 is a potential remedy for the treatment of sexual dysfunction; specifically, male erectile dysfunction. Studies have shown that PT-141 does not act on the vascular system like former compounds, but allegedly works by activating melanocortin receptors in the brain, therefore helping increase ones sexual stimulation.

PT-141 is a melanocortin based peptide that has shown effectiveness in clinical studies on both male and female rats. Male rats have shown erectile response with doses as low as 1-2 mgs whereas most female rats have shown positive results with higher doses around 2-3 mgs.

PT-141,Used as an erectile dysfunction solution, it is used by men who want to bring back the fire into their sex life in terms of achieving rock-hard erections that do not only satisfy them but their partners as well. In the process, they never have to take any other medications or choose hormone replacement therapy again with it at their side.
