Bronchogen
Summary
DSIP is an endogenous neuropeptide originally isolated from rabbit cerebrospinal fluid that induces delta-wave (deep) sleep. It also modulates stress response, cortisol regulation, and LH secretion, making it valuable for sleep optimization and stress management.
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.
Half-Life
~30–60 minutes; however downstream sleep effects last 4–6 hours
Short (minutes to hours); bioregulator effects are gene-mediated and longer lasting

Key Benefits
  • Induces and deepens delta-wave (slow-wave) sleep
  • Reduces cortisol and normalizes HPA axis
  • Improves sleep quality in insomnia patients
  • Anti-stress and anxiolytic effects
  • May improve opiate/alcohol withdrawal symptoms
  • Analgesic properties through opioid modulation
  • Antioxidant and neuroprotective effects
  • 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
Side Effects
  • Generally well tolerated
  • Mild grogginess next morning at higher doses
  • Rare: hypotension
  • Potential for altered dream patterns
  • Generally well tolerated in research studies
  • Mild local reactions at injection site (if injected)
  • No significant systemic side effects reported at standard doses
