Cartalax- Summary
- 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.
- Cartalax is a tetrapeptide bioregulator (Ala-Glu-Asp-Pro) developed by Professor Vladimir Khavinson for cartilage and connective tissue. It is tissue-specific for chondrocytes and cartilaginous structures, supporting cartilage matrix synthesis, slowing degenerative changes, and promoting joint longevity. It is used in the context of osteoarthritis, joint aging, and athletic cartilage preservation.
