PT-141 is a prescription peptide therapy used to support sexual desire in eligible adults. It works through the nervous system rather than directly increasing blood flow, and should be prescribed and monitored by a licensed healthcare provider.

If our licensed clinicians determine medication isn’t right for you after review, you don’t pay for medication. This covers clinical eligibility — individual results from any treatment vary and cannot be guaranteed.

U.S.-licensed clinicians, licensed compounding pharmacy partners, and ongoing support — all coordinated in one place. Prescriptions are issued only when clinically appropriate after individual evaluation.

Personalized approach

Treatment may be tailored to your needs and lifestyle. Not suitable for everyone, and individual responses may vary.

How does it work?

PT-141 stimulates the brain’s arousal centers through the melanocortin system:

CNS-Based Arousal Enhancement
PT-141 activates melanocortin receptors (MC3R and MC4R) in the hypothalamus, increasing sexual desire and drive by acting on the central nervous system.

Independent of Blood Flow

Unlike PDE5 inhibitors (like sildenafil or tadalafil), PT-141 does not depend on nitric oxide pathways or vascular mechanisms—making it effective for both genders and for arousal-related dysfunction.

Rapid, On-Demand Effect

Administered via subcutaneous injection 45–60 minutes before sexual activity, PT-141 enhances arousal, responsiveness, and sensitivity for several hours.

Questions, Answered.

PT-141 (Bremelanotide) is a centrally acting melanocortin receptor agonist used to enhance sexual desire and arousal in both men and women. Originally developed to treat sexual dysfunction, it is FDA-approved for hypoactive sexual desire disorder (HSDD) in premenopausal women and is also commonly used off-label in men with low libido or erectile dysfunction—especially when psychological or central causes are suspected. Unlike traditional ED medications, PT-141 works through the brain rather than blood flow.

PT-141 stimulates the brain’s arousal centers through the melanocortin system:

  1. CNS-Based Arousal Enhancement
    • PT-141 activates melanocortin receptors (MC3R and MC4R) in the hypothalamus, increasing sexual desire and drive by acting on the central nervous system.
  2. Independent of Blood Flow
    • Unlike PDE5 inhibitors (like sildenafil or tadalafil), PT-141 does not depend on nitric oxide pathways or vascular mechanisms—making it effective for both genders and for arousal-related dysfunction.
  3. Rapid, On-Demand Effect
    • Administered via subcutaneous injection 45–60 minutes before sexual activity, PT-141 enhances arousal, responsiveness, and sensitivity for several hours.
  • Inject 1 hour before sexual activity (typically 1.75mg dose)
  • Onset: 45–60 minutes, duration: 6–12 hours
  • Do not exceed 1 dose in 24 hours or 8 doses per month (per FDA guidelines for women)
  • Results improve with repeated, consistent use over time
  • Safe to combine with TRT, HRT, or PDE5s (under supervision)
  • Missed dose? PT-141 is on-demand—only use when needed

Taking 1 tablet daily helps most men reduce their PE issue. It may take a few weeks for the medication to reach its full effect, so be patient and continue following your doctor’s instructions. Sertraline needs to be taken daily. If you skip days or doses, you may not receive the full benefit for PE.

Common Side Effects:
• Nausea (transient)
• Flushing or warmth
• Headache
• Injection site reactions

Less Common / Monitor If Present:
• Elevated blood pressure (temporary)
• Fatigue or yawning
• Dizziness
• Darkening of gums or skin (rare with prolonged use)
