Pal-AHK
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.
Pal-AHK is the palmitoylated form of the AHK-Cu copper tripeptide, created by attaching a palmitic acid chain to enhance skin penetration and lipid bilayer affinity. The palmitoyl modification significantly improves dermal bioavailability compared to unmodified AHK, making it particularly effective in anti-aging and hair growth formulations.

Once or twice daily
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
  • Enhanced skin penetration vs. unmodified AHK-Cu
  • Stimulates dermal collagen and elastin production
  • Promotes hair follicle anagen phase
  • Antioxidant and wound healing activity
  • Firming and plumping effect on aging skin
  • Improved bioavailability via lipid bilayer incorporation
Side Effects
  • Generally well tolerated in research studies
  • Mild local reactions at injection site (if injected)
  • No significant systemic side effects reported at standard doses
  • Generally well-tolerated
  • Mild irritation at high concentrations in sensitive skin
  • Possible comedogenicity at very high palmitate concentrations (formulation-dependent)
