Leuprolide- Summary
- KPV is a naturally occurring anti-inflammatory tripeptide derived from the C-terminal of alpha-MSH. It powerfully suppresses intestinal and systemic inflammation via melanocortin receptors, making it valuable for IBD, gut healing, and wound repair.
- Leuprolide is a synthetic GnRH superagonist that, with continuous administration, paradoxically suppresses LH and FSH through receptor desensitization — the opposite effect of pulsatile GnRH. Used medically for prostate cancer, endometriosis, and precocious puberty. In men's health, short-duration use for PCT and testosterone suppression rebound.
- Half-Life
- Short half-life (~15–30 minutes), but effects persist longer due to receptor-level anti-inflammatory cascades
- ~3 hours (SC/IM), but depot formulations last 1–12 months
- Admin Route
- Oral, SubQ, Topical
