PEG-MGF- 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.
- PEG-MGF (Pegylated Mechano Growth Factor) is a modified form of MGF (Mechano Growth Factor) where polyethylene glycol (PEG) chains have been attached to extend its half-life from minutes to days. Native MGF is released locally in muscle in response to mechanical stress and quickly degrades. PEGylation allows systemic administration with sustained circulation, enabling whole-body muscle repair and anabolic signaling rather than the purely local effect of native MGF.
- Half-Life
- Short (minutes to hours); bioregulator effects are gene-mediated and longer lasting
- ~3 days (due to PEGylation)
- Admin Route

- 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
- Extended half-life (~3 days) vs native MGF (minutes)
- Systemic muscle satellite cell activation via subcutaneous injection
- Promotes muscle fiber repair and hypertrophy throughout the body
- Enhanced recovery from intense training or muscle injury
- Synergistic with IGF-1 LR3 and growth hormone peptides
- Useful in sarcopenia, post-injury recovery, and athletic performance
- Single injection provides multi-day anabolic signaling
- 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
- Water retention and localized swelling
