PT-141 (Bremelanotide)
A peptide studied for low sex drive. It works in the brain rather than on blood flow, which is what sets it apart from the pills people know.
Prescription only. A consultation does not guarantee a prescription. Compounded medications are not FDA-approved.
- Aimed at sex drive and arousal. People ask about this one when desire or arousal is not what it used to be. Your doctor will tell you whether it fits you.
- A shot, not a pill. It goes in under the skin with a short, fine needle. Most people do it themselves at home, once their doctor has shown them how.
- A doctor decides. Nothing ships until a doctor licensed in your state has read your health form and written a prescription. Signing up does not guarantee one.
PT-141, also called bremelanotide, is a peptide that acts on the melanocortin receptors in the brain. That is what separates it from the tablets most people have heard of, which work on blood flow. This one works on desire.
How it works
PT-141 lands on melanocortin-4 receptors in the hypothalamus. That is a small area near the base of the brain that handles drives like hunger and desire. It works on wanting rather than on plumbing. That is why it comes up when the interest itself is what has gone.
Who it's for
People ask about PT-141 when desire is the part that has changed and the blood-flow tablets have not helped. We also list it as a nasal spray. Your doctor decides which one fits you.

Common questions
What is PT-141 (bremelanotide)?
The molecule is FDA-approved as Vyleesi (bremelanotide injection) for hypoactive sexual desire disorder (HSDD) in premenopausal women. The PT-141 your doctor prescribes is not that branded product: National Health Rx compounds it under Section 503A as a patient-specific prescription, a different regulatory pathway than FDA approval of the specific compounded preparation.
How much do I take?
Your doctor decides that and prints it on your label. We don't list doses here, because the right amount depends on you and on the exact product the pharmacy makes. Always go by your label.
Who shouldn't take it?
Your doctor decides that. They look at your health history, the medicines you already take, and why you want it, and they'll tell you if PT-141 (Bremelanotide) isn't a good fit. Tell them if you're pregnant or breastfeeding.
Are there side effects?
Any prescription medicine can have them. Your doctor will go over what to watch for before you start, and the paperwork that comes with your order lists them. If something worries you, call your care team. Don't wait for your next check-in.
Will it affect my other medicines?
It might, so list everything you take when you sign up, including vitamins and supplements. Checking that list is part of your doctor's job, and it's not something a web page can answer.
Is this FDA approved?
No. It's made to order for you by a licensed pharmacy, which is called compounding. The FDA doesn't review or approve compounded medicines, and they aren't generic versions of brand-name drugs.
Who makes it?
National Health Rx, a licensed 503A compounding pharmacy. That means they mix each order for one patient at a time.
Where do you ship?
We'll confirm yours when you sign up.
