Bremelanotide (Vyleesi) vs Goserelin (Zoladex)
An educational, source-based comparison of Bremelanotide (Vyleesi) and Goserelin (Zoladex) — 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.
Decapeptide GnRH agonist delivered via biodegradable subcutaneous implant. Suppresses gonadotropin and sex hormone production through pituitary desensitization.
- Prostate cancer
- Breast cancer (premenopausal)
- Endometriosis
- • FDA-approved.
- • Testosterone/estrogen flare; menopausal symptoms.
