Frequently asked questions

What is the PT-141 injection used for?

PT-141 is another name for bremelanotide.4 FDA approved bremelanotide on June 21, 2019 as Vyleesi, a prescription drug.12 Its label covers one use: acquired, generalized hypoactive sexual desire disorder in premenopausal women, meaning low sexual desire that causes marked distress or interpersonal difficulty and is not due to another medical or psychiatric condition, relationship problems, or a medication or drug substance.3 A prescriber sets the dose. The PT-141 vial sold here is not that product. It is a vial labeled: For research use only. Not for human or veterinary use.

Where can I buy PT-141 peptide for men online?

The PT-141 vial is in this category, sold for laboratory research only, and its product page lists strengths, price and stock. The approved bremelanotide label says it is not indicated for this disorder in postmenopausal women or in men, and not indicated to enhance sexual performance.3 In August 2026 warning letters to two online peptide sellers, FDA called their research-labeled PT-141 an unapproved new drug.45

Where can I buy PT-141 nasal spray?

Not here. PT-141 is listed as a 10 mg vial, and no nasal spray is sold. The approved bremelanotide product comes only as a 1.75 mg/0.3 mL solution in a single-dose autoinjector for injection under the skin.62 The PT-141 education page covers the published research and the routes it used.
