PT-141 - 10mg
Bremelanotide, also known as PT-141, is a peptide that binds to the body's MC3R and MC4R melanocortin receptors and is comparable to the alpha MSH and melanocortin. When it binds, it activates the hypothalamus and other brain areas, increasing sexual desire. Although it was once believed to be utilized to treat both male and female sexual problems, studies have shown that it is also effective in premenopausal women. Therefore, PT-141 is also employed in women who naturally have sexual abnormalities such as female sexual arousal disorder and hypoactive sexual desire.
- The benefits of PT 141 Bremelanotide include:
- Higher sex drive and increased sexual desire
- Greater sexual frequency
- Treatment for erectile dysfunction and/or impotence
- Effective treatment for premenopausal women with Hypoactive Sexual Disorder
- Sexual Dysfunction in women (Sexual Arousal Disorder)
- Increased levels of natural energy.

Bremelanotide (PT-141) is similar to the human hormone alpha-MSH. This peptide was first investigated as a therapy for both men and women, however, it is currently also recommended to women, often in premenopausal age.
Similar to the naturally occurring hormone known as alpha-MSH, PT-141 is an agonist at melanocortin receptors. Early research has shown that the melanocortin hormone controls a variety of physiological processes in the human body. When this isolated hormone was given to animals, it enhanced their sexual abilities.
Studies have shown that PT 141 has agonistic qualities toward MC3R and MC4R melanocortin receptors, which largely cause heightened reactivity in the human body's central nervous system. In these studies, it was revealed that the peptide activates the neurons in the hypothalamus and causes an increase in immunoreactivity after interacting with the MC3R and MC4R receptors. Neurons in the surrounding region of the central nervous system also get stimulated as they intake the chemicals which then leads to sexual arousal in the study animals.
Erectile dysfunction may originate from vascular, neurogenic, and/or psychogenic problems. Between 12 and 35 million men in the United States and more than 150 million men globally are said to be affected by ED.
The American Sexual Health Association defines hypoactive sexual desire disorder in women as a lack of sexual ideas, fantasies, and/or interest in engaging in sexual activity that results in significant emotional suffering and/or issues in their relationship. This sexual condition in women might cause extra physical and mental issues.
In a 2003 phase 1 randomized double-blind placebo-controlled trial involving 24 healthy male participants without erectile dysfunction, it was discovered that the duration of rigid erections was significantly longer for test subjects who received intranasal doses of PT-141, lasting 140 minutes as opposed to 22 minutes in the placebo group. Less than 400 participants participated in a 2004 trial that discovered 1 mg of PT-141 might cause a statistically meaningful "erectile reaction."
Based on the aforementioned findings, phase II research was conducted to examine the safety and effectiveness of PT-141 in test individuals with ED. The injection of PT-141 led to a 3-fold increase in erectile function, according to the results. These results raise the possibility that PT-141 may be used as an alternative ED therapy for patients who do not react to sildenafil.
Furthermore, both test participants with and without ED showed that PT-141 made their erections stiffer. The fact that PT-141 may elicit sexual desire in both men and women without the need for sexual stimulation implies that it has the potential to be used as a therapy for many diseases of sexual desire.
The advantages of PT 141 Bremelanotide include:
● Enhanced sexual drive and desire
● more sexual activity
● Treatment for impotence and/or erectile dysfunction based on clinical study and approval
● Treatment for hypoactive sexual disorder in premenopausal women
● increased natural energy levels.
The most frequent adverse effect is nausea. Flushing and headache are some other, less frequent adverse effects. PT-141 was previously studied through intranasal delivery, however, this had the unintended side effect of raising blood pressure. By administering the peptide through subcutaneous injection, the incidence of increased blood pressure dropped substantially.
