Leuprolide- Summary
- Mazdutide is a once-weekly GLP-1/glucagon dual receptor agonist developed by Innovent Biologics and Eli Lilly. Phase 2 trials in Chinese populations demonstrated up to 11.3% body weight reduction at 6 mg over 24 weeks. It also improves liver fat, glycemic control, and lipid profiles. Phase 3 trials are ongoing primarily in China.
- 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.
