IGF-1 DES
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.
IGF-1 DES (also written DES(1-3)IGF-1) is a truncated form of IGF-1 missing the first three amino acids of the N-terminus. This structural change dramatically reduces its affinity for IGF binding proteins (IGFBPs), meaning a far greater fraction remains in its free, active form. IGF-1 DES is estimated to be 10x more potent than standard IGF-1 LR3 at the receptor level locally, making it particularly effective for site-specific muscle growth when injected intramuscularly.
Half-Life
Short (minutes to hours); bioregulator effects are gene-mediated and longer lasting
~20–30 minutes (very short — designed for local action)
Admin Route
SubQ, Oral
IM, SubQ
Research
Typical Dose
10 mg per day
20–50 mcg per injection site
Frequency
Daily for 10–30 days
Once daily, post-workout
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
  • Estimated 10x greater potency at the receptor vs IGF-1 LR3 locally
  • Minimal IGFBP binding — nearly all active upon injection
  • Highly localized muscle growth effect when injected intramuscularly
  • Activates satellite cells for muscle fiber hyperplasia potential
  • Synergistic with GH peptides in post-workout anabolic protocols
  • Shorter half-life reduces systemic exposure vs IGF-1 LR3
  • Useful for site-specific muscle development
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
  • Hypoglycemia (most significant risk — especially post-workout)
  • Localized muscle swelling at injection site
  • Potential for jaw/organ growth (acromegalic effects) with prolonged high-dose use
  • Carpal tunnel syndrome with high doses
