DSIP
Summary
Cardiogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Arg) developed by Professor Vladimir Khavinson. It is a tissue-specific bioregulator for the heart and myocardium, designed to normalize cardiomyocyte function and support cardiac tissue regeneration. Research has demonstrated cardioprotective effects, improved cardiac rhythm, and benefits in recovery from ischemic injury.
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.
Half-Life
Short (minutes); gene-regulatory effects persist longer
~30–60 minutes; however downstream sleep effects last 4–6 hours
Admin Route
SubQ, Oral
SubQ, IV, Intranasal
Research
Typical Dose
10 mg per day
100–400 mcg
Frequency
Daily for 10–30 days
Once nightly
Key Benefits
  • Cardioprotective effects on myocardial tissue
  • Normalization of cardiomyocyte protein synthesis
  • May improve cardiac rhythm and conduction
  • Support for recovery from ischemic cardiac events
  • Anti-aging effects on heart tissue
  • Potential reduction in cardiac fibrosis
  • Often combined with Epithalon for comprehensive cardiovascular longevity support
  • 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
Side Effects
  • Generally well tolerated in available research
  • Mild injection site reactions
  • No significant adverse cardiovascular events reported at standard doses
  • Generally well tolerated
  • Mild grogginess next morning at higher doses
  • Rare: hypotension
  • Potential for altered dream patterns
