PT-141 Sexual Health & Libido

ED medications (PDE5 inhibitors) work by increasing blood flow to the genitals — a peripheral vascular mechanism. PT-141 (Bremelanotide) works centrally by activating melanocortin receptors in the hypothalamus — the brain's desire center. This means it addresses the neurological component of sexual response, not just the vascular component.

Yes. PT-141 is uniquely effective for both men and women because it targets central desire pathways rather than genital blood flow. For women with hypoactive sexual desire disorder (HSDD), PT-141 offers a mechanism that PDE5 inhibitors cannot provide.

PT-141 is a subcutaneous injection administered approximately 45 minutes before desired effect. It is used on an as-needed basis — not as a daily protocol. A typical dose is 0.25–0.5 mL (25–50 units on the insulin syringes we include, or 0.5–1 mg at our 2 mg/mL concentration), with no more than one dose in 24 hours. Your provider sets your dose during intake.

At the typical 0.25–0.5 mL dose, a 5 mL vial covers about 10 to 20 uses and the 2 × 5 mL pack covers about 20 to 40 — which works out to roughly $9.95 to $24.90 a dose. Every order ships with enough sterile insulin syringes and alcohol prep pads to cover the full vial, so there is nothing extra to buy. Because PT-141 is used as needed rather than on a schedule, how long a vial lasts is up to you.

Common side effects include transient nausea, flushing, and headache — particularly at higher doses. These effects are typically mild and short-lived. Your provider will discuss appropriate dosing to minimize side effects while achieving the desired effect.

PT-141 (Bremelanotide, brand name Vyleesi) is FDA-approved for hypoactive sexual desire disorder (HSDD) in premenopausal women. For other indications, it is prescribed as a compounded medication. A licensed Affinity provider determines clinical appropriateness during your intake evaluation.

PT-141 and PDE5 inhibitors work through different mechanisms, making them potentially complementary. However, combination use should only occur under provider supervision. Your Affinity provider will evaluate your full medication list and health history before prescribing.

The most common side effects are temporary and usually mild — facial flushing, headache, and some nausea, which often eases after the first couple of uses. A few people notice nasal congestion or mild indigestion. PT-141 can briefly raise blood pressure, so it isn't prescribed for people with uncontrolled high blood pressure or heart disease. Taking it with a light snack and using the lowest effective dose keeps most people comfortable — and your provider is available if you have questions.

PT-141 briefly raises blood pressure, so it isn't appropriate for anyone with cardiovascular disease — including a history of heart attack or stroke — or high blood pressure (hypertension), or for anyone who is pregnant or breastfeeding. Your Affinity provider reviews your full health history during intake and won't prescribe it if it isn't safe for you.
