The science behind PT-141

Bremelanotide is FDA-approved only as the branded Vyleesi injector, for low sexual desire in premenopausal women. Chia dispenses a compounded bremelanotide nasal spray, which is not FDA-approved; use in men or after menopause is off-label. PT-141 (bremelanotide) works through the brain's melanocortin system to influence sexual desire — a different pathway from erection-focused drugs. It's FDA-approved for low desire in women, with human-trial evidence behind it.

FDA-approved for low desire

In two phase-3 trials of premenopausal women with low sexual desire, bremelanotide significantly improved desire and reduced distress versus placebo — the basis for its FDA approval as Vyleesi (Obstetrics & Gynecology, 2019).

A brain, not blood-flow, pathway

Bremelanotide activates melanocortin-4 receptors in the central nervous system — acting on the desire circuitry itself, unlike PDE5 inhibitors (Viagra-class) that work on blood flow (Journal of Sexual Medicine, 2016).

Studied in men too

In men with erectile dysfunction, subcutaneous bremelanotide produced erectile responses in an early controlled study — an off-label, investigational use in men (International Journal of Impotence Research, 2004).

On-demand, well-characterized

Nausea is very common (around 40% of users) and flushing is frequent; blood pressure is monitored, and it is avoided in uncontrolled hypertension or cardiovascular disease (Obstetrics & Gynecology, 2019).

What patients are saying

4.9 out of 5 from 256 reviews

"After two kids and a decade of marriage, desire had just quietly left the building. This is the first thing that brought back the spark of actually wanting to, not just going along with it."

Renee K.

DesireWomen

"I was skeptical that a shot could change something so mental. But it's not about plumbing — it's the interest that came back. My wife noticed before I said anything."

Daniel P.

DesireMen

"The on-demand part matters to me — I didn't want another daily pill. I use it before date night and it does what my doctor said it would."

Marco T.

On-demandArousal

"First time I had some nausea, so we adjusted the timing and dose. Since then it's been smooth, and the difference in how present I feel is real."

Alyssa M.

DesireWomen

"I'd tried the blue-pill route and it fixed the wrong problem. This works on wanting to in the first place, which turned out to be what was actually missing."

Grant H.

DesireMen

"My husband and I did this together, both curious. It reopened a part of our relationship we'd both stopped bringing up. Worth the awkward first conversation with the doctor."

Priscilla D.

CouplesDesire

"Stress and antidepressants had dialed me down to zero. Under my doctor's guidance, this gave me back a baseline of interest I thought was gone for good."

Frequently asked questions

PT-141 (bremelanotide) is a melanocortin-receptor agonist that works on the desire pathways in the brain rather than on blood flow. Bremelanotide is FDA-approved only as the branded Vyleesi injector for low sexual desire in premenopausal women. Chia dispenses a compounded bremelanotide nasal spray, which is not FDA-approved; use in men or after menopause is off-label and at your physician's discretion. In two phase-3 trials it significantly improved sexual desire and reduced the distress around it versus placebo (Obstetrics & Gynecology, 2019).

Erection drugs (PDE5 inhibitors, the Viagra class) work on blood flow — the physical response. PT-141 works earlier in the chain: it activates melanocortin-4 receptors in the central nervous system, the circuitry behind desire itself (Journal of Sexual Medicine, 2016). That's why it can help when the missing piece is wanting to, not just the mechanics. Many people find the two address different problems.

It's FDA-approved (as the Vyleesi injector) only for low sexual desire in premenopausal women. Use in men is off-label and still investigational: in early controlled studies subcutaneous bremelanotide produced erectile responses in men, but it is not FDA-approved for men and the evidence is not considered proven (International Journal of Impotence Research, 2004). Your physician confirms whether it fits your profile.

PT-141 is taken on-demand — roughly 45 minutes before intimacy — not every day. Chia prescribes it as a needle-free nasal spray you use at home, with the dose set by your physician. Because it's used as needed, there's no daily pill to remember.

Nausea is very common — it affects roughly 40% of people — and is often managed by adjusting dose or timing; flushing is also frequent. PT-141 can briefly raise blood pressure, so it's not used in uncontrolled hypertension or known cardiovascular disease, and your physician screens your history and monitors you (Obstetrics & Gynecology, 2019). This is a prescription therapy reviewed and supervised by a licensed US clinician — not something to source unsupervised.

PT-141 may be FSA/HSA eligible with a valid prescription — check with your plan administrator. Pay with your HSA/FSA card at checkout and email support@chia.health if your administrator needs documentation. You can cancel anytime through your patient portal. Before your consultation, before your first shipment, or if a provider finds you're not eligible, you get a full refund; we also offer a 30-day money-back refund on unused monthly plans.
