Degarelix (Firmagon) vs PT-141 (Bremelanotide)
An educational, source-based comparison of Degarelix (Firmagon) and PT-141 (Bremelanotide) — how each peptide works, what it's researched for, and what to know before going deeper.
GnRH antagonist providing immediate testosterone suppression in prostate cancer.
Synthetic decapeptide GnRH receptor antagonist. Blocks GnRH receptors directly, producing rapid suppression of LH, FSH, and testosterone without the initial flare seen with agonists.
- Advanced prostate cancer
- • FDA-approved.
- • Injection-site reactions 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.
