Bremelanotide (Vyleesi) vs PT-141 (Bremelanotide)
An educational, source-based comparison of Bremelanotide (Vyleesi) and PT-141 (Bremelanotide) — how each peptide works, what it's researched for, and what to know before going deeper.
Melanocortin receptor agonist for hypoactive sexual desire disorder in premenopausal women.
Cyclic 7-amino-acid synthetic analog of α-MSH that activates melanocortin receptors (primarily MC4R) in the CNS, modulating sexual desire pathways.
- Acquired, generalized hypoactive sexual desire disorder (HSDD) in premenopausal women
- • FDA-approved.
- • Nausea, flushing, transient BP elevation common.
Melanocortin agonist researched for sexual desire and arousal.
A synthetic analog of α-MSH that activates melanocortin receptors (primarily MC4R) in the central nervous system. Unlike PDE5 inhibitors, it acts on neural pathways governing sexual desire rather than vascular flow.
- Hypoactive sexual desire disorder (FDA-approved as Vyleesi in premenopausal women)
- Male erectile response (research)
- Central arousal pathways
- • FDA-approved (Vyleesi) only for HSDD in premenopausal women.
- • Can cause nausea, flushing, transient blood pressure increases.
- • Avoid in uncontrolled hypertension or cardiovascular disease.
