Cardiogen vs Dermorphin

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

Anti-Aging & Longevity
Cardiogen
Recovery & Repair
Dermorphin
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.
Dermorphin is a naturally occurring heptapeptide opioid isolated from the skin of South American phyllomedusine frogs. It is one of the most potent endogenous mu-opioid receptor agonists known, approximately 30-40 times more potent than morphine by weight. Explored for pain management and fatigue modulation.
Half-Life
Short (minutes); gene-regulatory effects persist longer
Estimated 30-60 minutes (longer than endorphins due to D-Ala)
Admin Route
SubQ, Oral
Subcutaneous (research), Intrathecal (research), Intranasal (research)
Research
Typical Dose
10 mg per day
Not established for human use; research doses vary widely
Frequency
Daily for 10–30 days
Not established
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
  • Potent analgesia superior to morphine on a per-weight basis
  • May reduce perception of fatigue in high-intensity activity
  • Longer-lasting than endogenous opioids due to D-amino acid substitution
  • Research tool for mu-opioid receptor pharmacology
  • Potential therapeutic application in refractory pain
Side Effects
  • Generally well tolerated in available research
  • Mild injection site reactions
  • No significant adverse cardiovascular events reported at standard doses
  • High addiction and dependence potential (mu-opioid agonism)
  • Respiratory depression at high doses
  • Nausea, vomiting, constipation
  • Sedation and cognitive impairment
