Bronchogen vs DS5

Side-by-side comparison of key properties, dosing, and research.

Anti-Aging & Longevity
Bronchogen
Sleep Optimization
DS5
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.
DS5 is a synthetic variant of the delta sleep-inducing peptide (DSIP), a nonapeptide originally isolated from rabbit cerebrospinal fluid during slow-wave sleep. Like DSIP, DS5 is explored for sleep optimization, stress modulation, and circadian rhythm normalization, with proposed improvements in potency or stability over the parent molecule.
Half-Life
Short (minutes to hours); bioregulator effects are gene-mediated and longer lasting
Estimated 30-60 minutes (peptide degradation)
Admin Route
SubQ, Oral
Subcutaneous, Intranasal (research)
Research
Typical Dose
10 mg per day
200-500 mcg per dose
Frequency
Daily for 10–30 days
Once nightly
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
  • Promotes delta-wave (deep) sleep and improves sleep quality
  • May reduce sleep onset latency
  • HPA axis modulation for stress reduction
  • Non-addictive sleep support without tolerance development
  • Potential circadian rhythm normalization
  • Explored for insomnia, chronic stress, and PTSD-related sleep disturbance
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 in research subjects
  • Possible morning grogginess at higher doses
  • Mild blood pressure fluctuations reported with DSIP
  • Limited human safety data for DS5 specifically
