Sexual Health Peptides
Peptides researched for sexual function, libido, and related wellness applications.
About Sexual Health Peptides
Sexual health peptides include compounds researched for their effects on libido, sexual function, and related physiological processes. PT-141 (Bremelanotide/Vyleesi) is FDA-approved for hypoactive sexual desire disorder in women. Melanotan II, while primarily known for tanning effects, also affects libido through melanocortin receptor activation. These peptides work through central nervous system pathways rather than vascular mechanisms like traditional ED medications.

Melanotan II
ResearchAlso: MT-II, MT2
Melanotan II is a synthetic copy of alpha-melanocyte-stimulating hormone (alpha-MSH), nicknamed the tanning peptide because it darkens skin without much sun. It also triggers erections and can blunt appetite, which is why it became the template for the FDA-approved drug bremelanotide (PT-141). Melanotan II itself is not approved by the FDA or EMA and is sold only as an unregulated research chemical.
PT-141
FDA ApprovedAlso: Bremelanotide, Vyleesi
PT-141, generic name bremelanotide and sold as Vyleesi, is a melanocortin peptide and a cyclic analog of alpha-MSH that works in the brain to boost sexual desire. It is genuinely FDA approved: in June 2019 it became the first on-demand treatment for acquired, generalized hypoactive sexual desire disorder (HSDD) in premenopausal women. It is also used off-label for low libido and erectile dysfunction in men.
Frequently Asked Questions About Sexual Health Peptides
What is PT-141?
PT-141 (Bremelanotide, brand name Vyleesi) is an FDA-approved peptide for treating hypoactive sexual desire disorder (HSDD) in premenopausal women. It works through melanocortin receptors in the brain, affecting sexual arousal pathways.
How is PT-141 different from Viagra?
PT-141 works through the central nervous system by activating melanocortin receptors, affecting desire and arousal at the brain level. Viagra and similar medications work through vascular mechanisms, primarily affecting blood flow for physical response.
Is Melanotan safe?
Melanotan II is not FDA approved and carries significant risks including nausea, facial flushing, and potential cardiovascular effects. There are also concerns about mole changes and melanoma risk. It should only be considered under medical supervision.
