PT-141 user reports can't tell what will happen to you
Researchers made the drug after a tanning study brought a sexual effect. Later trials found known harms; public posts remain personal stories.
User posts raise questions but don't prove a result
Tanning researchers saw an unexpected sexual effect, then made PT-141 to study it. Public posts about bremelanotide mention more desire, nausea, flushing, headache, or no change. The writers may not know whether they used the approved medicine, and their posts leave out other changes that day. Most do not compare the drug with an inactive shot. The posts can still give you useful questions for your doctor. Studies give firmer facts about nausea, short-lived higher blood pressure, darker skin, and rare liver harm. This page keeps personal stories apart from study findings.
Public posts mention desire and nausea most often
These public reports come from people using the compound for research. No controlled trial has tested the claims, and no trial result comes from them. The sources do not give a sound count of all users. Words such as "many" and "fewer" only compare topics in these posts; they can't give the odds of any effect.
The posts are not medical advice, and they can't predict what an approved shot would do to you.
What people wrote about desire and arousal
Many people wrote that their wish for sex returned. They described interest in the mind, not better blood flow. Many also wrote about more body arousal or a stronger response to touch; some felt aroused before direct touch, while others did not.
Some writers said orgasm felt easier or brought more pleasure once desire rose. No one can count on either result. Men also wrote about erections that began without direct touch; their posts don't prove an approved use for men.
Fewer people wrote about more closeness with a partner than about desire. Many described a slow start followed by effects that lasted for a while. Some liked that pace, but others found the timing hard to judge.
What people wrote about harm or no benefit
Some people felt no benefit even though they felt ill. Others noticed darker gums or skin, including freckles and moles; a few said the deeper color did not fully fade.
Some writers felt tired or sleepy on the same day. Others noticed tingling, pins-and-needles, or a sharper sense of touch. Flushing or a brief keyed-up feeling sometimes came with those effects.
Many writers reported soreness, redness, or a small bump where the needle entered. Headaches also appeared often; the pain tended to fade as the other short effects passed.
Flushing felt like brief heat or redness on the neck, chest, or face. Nausea brought the most complaints. Writers described mild queasiness through vomiting; some felt the sickness outweighed any gain.
Studies and the drug label give firmer warnings
The warnings below come from drug studies, the US label, or lab checks. They carry more weight than a personal post, while gaps remain for groups not studied well.
Who the approval covers. US approval covers women who have not passed menopause. Their loss of desire must start later, happen in every setting, and cause distress. The drug agency did not approve the drug for older women, men, or those seeking better performance. Other use is not always illegal, but the same proof does not support it. [7][16][3]
Heart health and blood pressure. Blood pressure rises briefly as the heart rate falls a little. The label bars the drug for poorly controlled high blood pressure and known heart or blood-vessel disease. Studies support both warnings. [7][17][18]
Nausea and vomiting. About forty percent of long-term users felt sick, and some stopped the drug. The illness ranged from mild nausea to vomiting, making sickness one of the main limits on use. [4][8][3]
Darker skin. Repeated use may darken the gums or face. Breasts, freckles, and moles may darken too. People who started with darker skin had more risk, and the color did not always fade. [7]
Liver harm. The NIH LiverTox review notes mild changes on liver blood tests and rare cases of clear liver injury. The harm is uncommon, but your doctor needs to know about it. [10]
Unchecked online supply. Material bought outside a pharmacy may not match its label; the strength and cleanliness may be unknown. Lab checks found illegal products in use. One person suffered severe muscle breakdown and kidney trouble after injecting a related tanning product. That case does not prove bremelanotide causes the same harm. [12][19]
Eating and weight. The part of the brain linked with sexual interest also helps govern hunger. In frequent-use studies, women ate less and lost weight. Those findings do not make the drug an approved weight-loss drug. [20][21]
Pregnancy and breast-feeding. There isn't enough proof. Studies in people haven't established safe use by pregnant or breast-feeding women. The lack of proof is the key fact for you.
A tanning drug led to a shot for certain women
Researchers first made melanotan-II while seeking a tanning drug. An unexpected sexual effect led them to PT-141. Early studies tested a nose spray for erection problems in men and sexual problems in women. Later work moved to a shot and focused on women. In June 2019, the United States approved bremelanotide for women who had not passed menopause. Their lasting low desire also had to cause distress. The earlier uses did not gain approval.
