Dermorphin vs TB-500

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

Recovery & Repair
Dermorphin
Recovery & Repair
TB-500
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.
TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring peptide found in nearly all human and animal cells. It promotes cell migration to injury sites, accelerates tissue regeneration, and reduces chronic inflammation.
Half-Life
Estimated 30-60 minutes (longer than endorphins due to D-Ala)
2–3 hours
Admin Route
Subcutaneous (research), Intrathecal (research), Intranasal (research)
SubQ, IM
Research
Typical Dose
Not established for human use; research doses vary widely
2–2.5 mg
Frequency
Not established
Twice weekly
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
  • Enhances muscle tissue regeneration
  • Accelerates healing of wounds and injuries
  • Reduces inflammation and pain
  • Improves flexibility and mobility
  • Promotes new blood vessel formation
  • Supports hair growth and skin health
  • May improve cardiac function after injury
  • Systemic healing effect — works at distance from injection site
Side Effects
