Product Information
PT-141, also called Bremelanotide, is a synthetic peptide developed from melanocortin research. It is best known for its interaction with melanocortin receptors, particularly pathways linked to sexual desire and arousal signaling in the brain.
This makes PT-141 different from many traditional sexual performance products, which often focus mainly on circulation or blood flow. PT-141 is commonly discussed in relation to desire, intimacy, and arousal response because of its central mechanism of action.
Bremelanotide has also been clinically studied and is recognized in prescription form for certain cases of low sexual desire in premenopausal women. However, peptide products should not be viewed as a substitute for medical diagnosis, treatment, or professional care.
For buyers, PT-141 10mg offers a focused peptide option for sexual wellness routines where desire, confidence, and intimacy support are the primary goals.

Common Questions
Frequently Asked Questions
What is PT-141 (Bremelanotide) and what receptor does it act on? +
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide that acts as an agonist at melanocortin receptors — primarily MC4R in the central nervous system. It is studied for sexual function and desire research. Unlike PDE5 inhibitors, it acts centrally rather than through vascular pathways. The brand name Vyleesi is FDA-approved for HSDD in premenopausal women.
How much BAC water should I add to a 10mg PT-141 vial? +
A standard reconstitution is 2 mL of bacteriostatic water, giving 5 mg/mL (5,000 mcg/mL). At this concentration a 1,000 mcg (1 mg) dose = 20 units on a U-100 syringe. Use the reconstitution calculator on this page for your specific target dose.
How many doses does a 10mg PT-141 vial provide? +
With 2 mL BAC water (5 mg/mL), the 10mg vial provides approximately 10 doses at 1 mg (1,000 mcg) per dose, or 20 doses at 500 mcg per dose. Research protocols typically use PT-141 at 1–2 mg per session.
Is PT-141 the same as Melanotan II? +
No. PT-141 (Bremelanotide) was derived from Melanotan II but is structurally distinct — it is a cyclic heptapeptide without the melanotropic effects that cause tanning. PT-141 lacks the alpha-MSH-like activity of Melanotan II and was specifically developed to target MC4R for sexual function research with a different side-effect profile.
How should reconstituted PT-141 be stored? +
Refrigerate at 2–8 °C after reconstitution and use within 28–30 days. Store the sealed lyophilized vial frozen at ≤ −20 °C, away from light. PT-141 is also soluble in DMSO if needed for specific research applications.
