Leuprolide- Summary
- Pancragen is a tripeptide bioregulator (Lys-Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for the pancreas. It supports the function of both exocrine and endocrine pancreatic cells, promotes normalization of insulin secretion from beta cells, and may offer protective effects against pancreatic aging and diabetic progression.
- 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.
