PT-141

The only peptide approved for treating sexual dysfunction in both men and women. PT-141 (Bremelanotide) works centrally on melanocortin receptors in the brain to naturally enhance libido, arousal, and sexual satisfaction — without the cardiovascular effects of PDE5 inhibitors.

What is PT-141?

PT-141, also known as Bremelanotide, is a synthetic peptide derived from Melanotan II. It is the first and only FDA-approved medication that works on the central nervous system — specifically the melanocortin system — to treat hypoactive sexual desire disorder (HSDD) in premenopausal women. Off-label use for men has shown strong results.

How It Works

Unlike Viagra or Cialis which work on blood flow, PT-141 activates melanocortin-4 receptors (MC4R) in the hypothalamus — the brain's sexual desire center. This triggers genuine desire and arousal at the neurological level rather than simply increasing blood flow to the genitals.

What to Expect

PT-141 is typically administered as a subcutaneous injection 30–60 minutes before desired effect. Most patients report increased desire and arousal within 45 minutes. Effects can last 4–12 hours. Your provider will guide you on dosing based on your health profile.

Mechanism

How PT-141 Works

PT-141 (bremelanotide) works centrally through the nervous system — not peripherally — making it unique among sexual health treatments.

01

Central Activation

PT-141 binds to melanocortin receptors (MC3R and MC4R) in the hypothalamus — the brain's center for sexual arousal. This central mechanism means it works even in patients unresponsive to PDE5 inhibitors.

02

Dopamine Pathway

Melanocortin receptor activation triggers dopamine release in the limbic system, increasing feelings of desire and motivation. This makes PT-141 effective for both physical and psychological components of sexual dysfunction.

03

Downstream Response

The central signaling cascade promotes increased blood flow, genital sensitivity, and arousal in both men and women. Onset typically occurs within 30–45 minutes of injection and lasts 6–12 hours.

Clinical Evidence

What the Trials Show

PT-141 has been studied in both male and female sexual dysfunction with notable results.

59%

Male Erectile Function Trial

A Phase 2b placebo-controlled trial of men with erectile dysfunction found that 59% of PT-141 subjects reported successful sexual activity, versus 25% in the placebo group. Notably effective in men with psychogenic ED unresponsive to sildenafil.

HSDD

Female Sexual Desire Trial

In premenopausal women with hypoactive sexual desire disorder, bremelanotide significantly increased satisfying sexual events and reduced personal distress scores compared to placebo in Phase 3 trials.

Patient Experience

What to Expect Over Time

Most patients report a predictable progression of results as they continue therapy.

Day 1

First Dose

Onset within 30–45 minutes. Most patients experience mild flushing and increased arousal within the first use. Some mild nausea is possible at higher doses.

Week 2

Dose Calibration

Your provider may adjust dosing based on your response. Side effects like nausea typically diminish as the body acclimates and the dose is dialed in.

Month 1

Consistent Results

By the end of the first month most patients report predictable, reliable arousal responses. Psychological confidence often improves alongside physical effects.

Month 3+

Long-Term Use

Patients on ongoing therapy report sustained improvements in desire, satisfaction, and relationship wellbeing. Provider check-ins ensure dosing remains optimized.
