Sexual desire
Premenopausal women with low desire used 1.75 mg as needed, before sexual activity.
Compared with placebo, desire went up and related distress went down. Nausea, flushing and headache were more frequent with bremelanotide.
Bremelanotide: a peptide studied for sexual desire that acts on receptors in the brain.
Purity 99.719% verified by Janoshik. Lot PT05261410K.





PT-141 is bremelanotide, a cyclic peptide of seven amino acids. There's an approved medicine containing bremelanotide for low sexual desire in premenopausal women.
It's studied for sexual desire and arousal, in women and in men.
It activates melanocortin receptors in the brain, which play a part in desire. It works on the desire signal, not on blood flow like sildenafil.
The analysis of the lot we're selling today, done by Janoshik, an independent lab.

Janoshik analyzed a sample from lot PT05261410K. The result applies to that sample, not to every vial in the lot.
Reconstituting means mixing the powder in the vial with bacteriostatic water to get a solution that's ready to use. The peptide comes as a powder because it keeps better that way.
The same 6 steps as the video. Tap an image to see it full size.
Afterward: label the vial with the date you reconstituted it and keep it in the fridge (see Storage).
Once reconstituted, it needs cold and darkness.
It's used only when you need it, not every day. Start with the low dose and go up only if you don't notice an effect: nausea is more common at higher doses.

Nausea depends on the dose. Try the low dose more than once before moving to the medium one.
The effect usually starts 45 to 60 minutes after the injection and lasts several hours.
One dose in 24 hours at most. Write down the date and the dose to find the one that works for you.
It's the most common. Forums suggest eating something light beforehand and lying down for a few minutes after the injection. It usually eases with later doses.
Brief warmth or redness. It's common and goes away on its own.
Drink water and rest. If it keeps happening, use a lower dose.
Bremelanotide can raise it temporarily. Keep that in mind if you use other products for sexual function.
No. It's used only when you need it, about 45 minutes beforehand. In the studies it was used at most once in 24 hours and 8 times a month.
There are no large trials in men. The medicine is approved for women; in men there are small studies, in erectile dysfunction. It acts on desire, not only on erection.
Start with the low dose (500 mcg). If you don't notice an effect after using it a couple of times, move to the medium dose; the high dose is for people who tolerate the medium one well.
Sildenafil increases blood flow. Bremelanotide acts in the brain, on desire. That's why it's described as a different mechanism.
