PT 141 Peptide Overview: Sexual Treatment, Benefits, Dosages

More and more people are looking at PT 141 (bremelanotide) as the go-to cure for sexual health problems. While it doesn’t cure all sexual ailments, it is a compound that does great things for people’s sexual dysfunction and arousal. People all around the world who experience problems with their sex lives need this medicine to help improve intimacy. One great thing about it is that the peptide produces few cardiovascular side effects, making it a game-changer for the elderly population who have a greater risk of strokes and heart attacks. Several clinical trials revealed the effectiveness of this substance, and it has been approved by the FDA for female treatment. Although the approval isn’t yet out for men, data is promising and a number of scientific papers cite the substance’s positive effects on male sexual health. Let’s discover more.

What is PT-141?

pt 141 formula

PT-141 is a peptide hormone treatment that is mainly innovative for improving sexual function in both men and women. It is a derivative for Melanotan II, more specifically a synthetic cyclic heptapeptide derivative of the alpha-MSH hormone. Its chemical makeup means that it works as a non-selective agonist for receptors MC1 to MC5, which are found primarily in the body’s nervous system. 

You may have heard it more commonly referred to as Vyleesi, Bremelanotide, or the “sex peptide” as it produces a positive sexual response. Other than the enhancement of sexual libido, consumers can also benefit from enhanced energy levels and greater arousal. 

As for the question “Is pt 141 legal?” – after many years of research and clinical trials, the peptide was finally approved by the FDA in 2016, as a treatment for sexual dysfunction in premenopausal females.

PT 141 Background

Initially, peptide pt-141 made its way into research as a possible tanning agent for UV-free or “sunless” tanning. By applying this agent, it was thought that the application could produce the effect of a tan on the body, commonly referred to as a fake tan. Melanotan II tests revealed some darkening pigmentation but also led to a heightened state of sexual arousal and spontaneous erections in many male volunteers. There was a dawning realization, that pt-141 peptide could contribute better as a treatment for sexual disorders, particularly erectile dysfunction in men and a lack of sexual arousal in women. This became especially apparent after a leading scientist self-experimented on themselves, injecting the compound into their body. As a result, they had an erection for eight hours. However, it wasn’t until many years later that the drug got approval from the FDA as initially there were discrepancies regarding elevated blood pressure and trials had to be postponed.

Both Hypoactive Sexual Desire Disorder (HSSD) and Inhibited Sexual Desire (IDS) are considered sexual dysfunctions that lead to both an absence of sexual fantasy or sexual desire. In particular, Female Sexual Arousal Disorder (FSAD) renders women unable to maintain arousal or even attain sexual arousal during periods of sexual activity. 

Pt-141 acts as a synthetic manmade aphrodisiac and is unlike many other related PDE5 inhibitor medicines such as Cialis and Viagra. The interesting thing about Pt 141 is that it doesn’t act upon the vascular system, rather it works directly on the hypothalamus in the brain to increase feelings of desire. Common medicines such as Viagra or Levitra aren’t aphrodisiacs and have no effect on a person’s libido, yet when used in combination with Pt-141 they are known to produce a synergistic effect.

Who Is This Peptide For?

If you look at peptides reviews online, you’ll likely notice that most people using this substance are those who experience some degree of failing sexual health. This peptide is particularly for those who have troubles with sexual dysfunction. Unlike a lot of other common sex substances, this substance is for both men and women.

How Does It Work?

Pt-141 for men and women works on the nervous system, increasing satisfaction, desire, and sexual arousal. Unlike other treatments that work on the vascular system and only give one the ability to maintain an erection, this substance creates motivation and desire along with an erection. It works just as well in females as males too, helping to boost libido. 

The result is that consumers can enjoy the passion and intimacy of their relationships. In some essence they are the best peptides for sexual health because they work on the nervous system and do not affect cardiovascular health – this makes them safe for a diverse population, including those who are prone to heart conditions.

The peptide stimulates the production of dopamine hormones which increase sexual motivation. Dopamine is a common neurotransmitter that is responsible for performance – when you don’t produce enough of it, you can feel depressed and have a low libido in general. While pt 141 works to boost sexual health, it can also be great for increasing natural energy levels without resorting to harmful means such as drinks or pills. Moreover, the effects of pt 141 make it a great option as a fake tan, helping people get darker skin much faster than with conventional tanning methods.

PT 141 Benefits: Scientific Evidence

Even though there are plenty of positive peptides reviews online, it is important to consider the scientific evidence when taking substances for yourself. Studies on bremelanotide pt-141 in journals such as Nature reveal conclusive evidence of pt 141 nasal spray increasing erectile response. This study conducted in healthy male participants showed a statistically significant increase in erectile response when compared to a placebo, with an erection occurring after 30 minutes. Similarly, a 2003 study by Molinoff et al. found that an administration of pt 141 to patients experiencing erectile dysfunction created a rapid increase in erectile activity, holding “promise as a new treatment for sexual dysfunction.” Results such as these have been echoed in double-blind trials of the substance on healthy humans.

General Benefits  

Although key studies such as those by Clayton et al indicate the peptide’s use for combating sexual health problems, there are all sorts of other benefits to pt-141 intake. 

There are even benefits unrelated to sexual health:

●     Anti-cancer properties – the MC-1R receptor works as a stimulus in DNA pathway repair. For this reason, scientists see potential in its future as a cancer treatment.

●     Anti-inflammatory properties – research has found MC-1R to harbor a number of important anti-inflammatory properties. Current research is underway, investigating the substance’s future as a fungal infection treatment.

●     Tanned skin – initially the substance was investigated as a tanning agent. One can apply pt-141 superficially to heighten the appearance of tanning.

●     Promotes skin tanning – on top of a superficial application, the peptide can create a darkening of skin pigmentation when injected into the body.

●     Increase in energy levels – early trials of pt141 concluded that it increases people’s energy levels. 

Extra Benefits For Men

Many effects of bremelanotide for men have been well documented:

●     Treatment of erectile dysfunction – The substance creates erections for men, helping to cure premature ejaculation, as well as impotence.

●     More frequent erections – males experience more frequent erections. Erections also last a lot longer, between 2-6 hours on average. Double-blind trials found that the substance is effective in treating sexual dysfunction, erectile dysfunction, impotence, and premature ejaculation.

●     General health benefits – this substance is much less likely to lead to heart attacks or strokes compared to other medications such as Viagra.

Extra Benefits For Women 

Looking at numerous pt 141 women’s reviews you’ll see that the benefits aren’t only for men, they are for women too. The research found in scientific literature, including a multidisciplinary review by the FDA, outlines some benefits to females:

●     Treatment of generalized hypoactive sexual desire disorder – this is by far the largest benefit to women. More blood flows to the sexual organs and consumers note feelings of greater libido, as well as more pleasurable sexual activity.

●     Vasocongestion – sexual arousal, menstruation and several different factors can create vasocongestion in humans. Pt 141 can be used as a treatment.

●     Pelvic floor strength – one side effect of peptide 141 is that it creates a strengthening of the pelvic floor, working wonders for general female health.

Using PT-141              

There are numerous ways to take the peptide compound, such as sprays or direct injections. Usually, doctors recommend taking a dose 45 minutes before sexual intercourse. The FDA recommends that consumers should not exceed one dose per 24 hours or 8 doses a month. If no improvement in sexual libido or arousal is achieved after an 8 week period of use, you should consult a doctor.

PT-141 Dosage
