Dermorphin vs Cardiogen

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

Recovery & Repair
Dermorphin
Anti-Aging & Longevity
Cardiogen
Summary
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.
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.
Half-Life
Estimated 30-60 minutes (longer than endorphins due to D-Ala)
Short (minutes); gene-regulatory effects persist longer
Admin Route
Subcutaneous (research), Intrathecal (research), Intranasal (research)
SubQ, Oral
Research
Typical Dose
Not established for human use; research doses vary widely
10 mg per day
Frequency
Not established
Daily for 10–30 days
Key Benefits
  • 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
  • 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
Side Effects
  • High addiction and dependence potential (mu-opioid agonism)
  • Respiratory depression at high doses
  • Nausea, vomiting, constipation
  • Sedation and cognitive impairment
  • +2 more
  • Generally well tolerated in available research
  • Mild injection site reactions
  • No significant adverse cardiovascular events reported at standard doses
