An educational, source-based comparison of Histrelin (Supprelin LA / Vantas) and Leuprolide (Lupron) — 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.
GnRH agonist used for prostate cancer, endometriosis, and precocious puberty.
Synthetic nonapeptide GnRH agonist. Continuous administration desensitizes pituitary GnRH receptors, suppressing LH/FSH and downstream sex hormone production (medical castration).
- Advanced prostate cancer
- Endometriosis
- Uterine fibroids
- Central precocious puberty
- Gender-affirming care
- • FDA-approved.
- • Initial testosterone flare; hot flashes, bone density loss with long-term use.
