About this listen

Bremelanotide, also known as PT-141, is one of the most misunderstood sexual health medications available today, and it has one of the strangest origin stories in modern medicine. It was originally studied as a tanning drug, but researchers noticed an unexpected side effect—spontaneous erections. That discovery led scientists to remove the skin-darkening component, resulting in bremelanotide as we know it today.

In this episode, we explain how PT-141 works on the brain rather than blood flow, why it’s considered an option for psychogenic erectile dysfunction in men, and why the same medication is used to increase sexual arousal in women. We break down what it does, what it doesn’t do, common misconceptions, and how it fits into a more honest conversation about desire, arousal, and sexual health.

That’s the short version. The full story is more nuanced, more interesting, and challenges a lot of what people think they know about ED meds and libido. To understand why bremelanotide works so differently—and who it may actually be appropriate for—you’ll have to listen to the episode.
