Bremelanotide (Vyleesi) vs Histrelin (Supprelin LA / Vantas)
An educational, source-based comparison of Bremelanotide (Vyleesi) and Histrelin (Supprelin LA / Vantas) — 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.
GnRH agonist implant for central precocious puberty and prostate cancer.
Synthetic nonapeptide GnRH agonist delivered via a subcutaneous hydrogel implant providing continuous release for 12 months, desensitizing the pituitary and suppressing sex steroids.
- Central precocious puberty (Supprelin LA)
- Advanced prostate cancer (Vantas)
- • FDA-approved.
- • Implant site reactions and rare implant breakage at removal.
