Desire, in women as in men
At the moment you choose
at least 45 min before (label)The brain, not blood flow
An effect on desire that works through the brain, taken as needed rather than every day.
Desire, in women as in men
Two phase 3 trials in 1,267 women measured a significant rise in desire against placebo, and phase 2 trials studied it in men.
At the moment you choose
The label of its molecule, approved in the United States since 2019, calls for use as needed, not every day.
Use planned at least 45 minutes before the intended moment, according to that label.
The brain, not blood flow
It activates the MC4R receptor in the hypothalamus and modulates dopamine in the motivation circuits.

People choose it for desire, in women as in men, with a molecule approved in the United States since 2019 after two phase 3 trials.
What it is: A 7-amino-acid cyclic peptide that activates the MC4R receptor in the hypothalamus: it acts on desire in the brain, not on blood flow.
Documented in humans
Approved in the United States since 2019 after two phase 3 trials in 1,267 women, PT-141 (bremelanotide) acts on desire itself, in the brain.
This cyclic seven-amino-acid peptide activates the MC4R receptor in the hypothalamus.
Why people choose it:
- Desire in women: in two phase 3 trials, desire increased and the distress linked to its loss decreased, significantly against placebo.
- Response in men: in phase 2, erection and desire increased against placebo, with an onset of effect at about 30 minutes (2004).
- Fast effect: peak blood level about one hour after injection, with a bioavailability of about 100% (FDA label).
- Lasting effect: users report 6 to 12 hours of effect on desire.
It is the only peptide in our catalogue whose molecule is approved for sexual desire.

Storage
Good for 6 weeks after reconstitution, if it has been kept properly: in the fridge, away from light, with an alcohol swab on the tip before each use. Past that, we do not recommend using it, even if some is left; if the liquid turns cloudy or changes colour, do not use it, even before.

Scientific studies3 studies
2019 · Kingsberg et al., Obstetrics and Gynecology (RECONNECT trials) · Two randomized, placebo-controlled phase 3 trials, premenopausal women with hypoactive sexual desire disorder
Significant increase in desire and decreased distress related to its decline compared with placebo; nausea was the main adverse effect, especially at the start.
2008 · Safarinejad and Hosseini, Journal of Urology · Randomized, placebo-controlled trial in men who did not respond adequately to sildenafil
Improved erectile function in a substantial share of participants, showing the value of a central mechanism where the vascular pathway isn't enough.
2004 · Diamond et al., Urology · Double-blind, placebo-controlled trial in men with erectile dysfunction
Increased erectile response and desire on bremelanotide, including without visual stimulation: the central effect is confirmed.
