Thymagen vs Dermorphin

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

Immune Support
Thymagen
Recovery & Repair
Dermorphin
Summary
Thymagen is a dipeptide bioregulator (Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for the thymus gland. It supports T-lymphocyte maturation, thymic function, and immune system normalization. As the thymus involutes with age (thymic atrophy), immune competence declines. Thymagen is used to support immune restoration, particularly in aging, post-illness recovery, and immunodeficiency states.
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); sustained gene-regulatory effects
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
  • Supports thymic epithelial cell function and T-cell maturation
  • May partially restore thymic output reduced by age-related atrophy
  • Normalizes T-lymphocyte subpopulation balance
  • Supports immune recovery after illness, surgery, or chemotherapy
  • Anti-aging effects on thymic tissue
  • Complementary to Thymosin Alpha-1 and Thymalin in immune protocols
  • May improve vaccine responsiveness in older individuals
  • 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
  • Mild injection site reactions
  • No significant immunological adverse events reported
  • High addiction and dependence potential (mu-opioid agonism)
  • Respiratory depression at high doses
  • Nausea, vomiting, constipation
  • Sedation and cognitive impairment
