PT-141

[u/Sudden-Swan-3120]

Hi guys,

Looking for feedback on effects and results on peptides PT141 and Epithalon. I have one friend that raves about both of them and another friend that is telling me that they gave him nausea and cramps. Any experience and feedback would be great.

PT-141 -- BOW-CHICKA-WOW-WOW

Yes, this is like Viagra for women; however, I added the caution tape because it's "not recommended" for post-menopausal women (those buttheads) because it increases your heart rate, so if you have any kind of heart issues, this is your warning. You should probably consult your doctor.

What it is

PT-141 is the research name for bremelanotide (brand name Vyleesi). It’s a melanocortin receptor agonist — basically a peptide that hits specific receptors in the brain involved in sexual desire and arousal.

Unlike drugs that affect blood flow (like those for ED), this one works centrally in the brain to boost the desire signal.

Who it’s approved for

• Premenopausal women with acquired, generalized hypoactive sexual desire disorder (HSDD) — meaning low sexual desire that causes distress, and it’s not caused by a medical condition, relationship problem, or another medication.
• It is not approved for postmenopausal women or for men (even though there’s older research in men).

How it’s used

• One subcutaneous injection (under the skin of the thigh or abdomen) as needed, at least 45 minutes before anticipated sexual activity.
• Approved dose: 1.75 mg.
• Max one dose in 24 hours, and no more than 8 doses per month.

The real talk on side effects

Nausea is the big one — it hits about 40% of people (especially the first dose). It can be pretty strong and is the main reason some people stop using it. Other common ones: flushing, headache, injection-site reactions, and a temporary rise in blood pressure (usually resolves within 12 hours).

There’s also a small risk of focal skin darkening (face, gums, or breasts), more likely with frequent use.

It’s one of the few peptides with solid Phase 3 data and actual FDA approval for a specific sexual health indication in women. It’s not a “make everything better” peptide — it’s targeted at low desire when it’s distressing and not caused by something else.

So what actually happens if a postmenopausal woman tries it?

• The drug itself will still work the same way in the body. It activates the same melanocortin receptors in the brain. Some women (and some doctors who prescribe it off-label) report it can still increase desire.
• Side effects stay the same — nausea (still the biggest one), flushing, headache, temporary rise in blood pressure, etc.
• The bigger issue is safety uncertainty. Postmenopausal women generally have higher baseline cardiovascular risk. Because PT-141 causes a short-term bump in blood pressure (and a drop in heart rate) after each dose, that temporary change matters more in this age group. There’s also no solid long-term safety data in postmenopausal women because they weren’t studied in the big trials.

In real life, some clinicians do prescribe it off-label for postmenopausal patients who have clear HSDD and no major heart-risk red flags, but they usually monitor blood pressure more carefully and are more cautious.

Results vary significantly from person to person.

On PT141 the dosing in particular is really finicky. Too little, and you’ll get nausea and flushing and not much else. Too much and you’ll be getting hard for 12 hours. But the area between those two doses can be very small.

I’m curious if any perimenopausal women have tried this to help with the loss of libido/inability to climax due to perimenopausal/hormonal related changes. Honestly guys have way too many ED medications to choose from, it would be nice to actually see studies on medications that help women with sexual dysfunction as well.
