Gonadorelin
Summary
Bronchogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Leu) developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It is a tissue-specific bioregulator designed for the bronchi and lungs, promoting normalization of bronchial epithelial cell function. Research suggests benefits for respiratory health, protection against pulmonary aging, and support for bronchopulmonary conditions.
Gonadorelin is the synthetic form of endogenous GnRH (gonadotropin-releasing hormone). It stimulates the pituitary to release LH and FSH, maintaining testicular function and testosterone production. Widely used alongside TRT to prevent testicular atrophy and preserve fertility.
Half-Life
Short (minutes to hours); bioregulator effects are gene-mediated and longer lasting
~2–4 minutes (extremely short); pulsatile dosing required to avoid desensitization

Key Benefits
  • Tissue-specific support for bronchial and lung health
  • Promotes normalization of bronchial epithelial cell function
  • Potential benefits in chronic bronchitis and COPD support
  • Anti-aging effects on pulmonary tissue
  • May reduce frequency of respiratory infections
  • Supports lung function preservation with aging
  • Compatible with other Khavinson bioregulator peptides
  • Maintains testicular size during TRT
  • Preserves fertility and sperm production during testosterone use
  • Stimulates endogenous LH/FSH production
  • Maintains HPG axis function during exogenous hormone use
  • Used for HCG-free TRT protocols
  • Helps restart natural testosterone production (PCT)
Side Effects
