Common questions

Is PT-141 the same as Vyleesi?
Yes. The FDA approved bremelanotide as Vyleesi in June 2019, for hypoactive sexual desire disorder in premenopausal women. It is the same molecule sold in research channels as PT-141.
Is PT-141 approved for general use?
The approval covers one population and one indication. Material sold as PT-141 outside a pharmacy is not the approved product and has not been through the same manufacturing controls.
How much research exists on bremelanotide?
One hundred and nine PubMed records, of which eighty are tagged to human subjects and fifteen are typed as clinical trials. That is a real but small literature, and it sits almost entirely within the approved indication.
