Histrelin (Supprelin LA / Vantas) vs PT-141 (Bremelanotide)
An educational, source-based comparison of Histrelin (Supprelin LA / Vantas) and PT-141 (Bremelanotide) — how each peptide works, what it's researched for, and what to know before going deeper.
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.
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.
