Dermorphin vs Melanotan II

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

Recovery & Repair
Dermorphin
Sexual Health & Libido
Melanotan II
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.
Melanotan II is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH) that stimulates melanin production (skin tanning), suppresses appetite, and enhances sexual function. It is not FDA-approved and has significant safety concerns including mole changes and cardiovascular effects.
Half-Life
Estimated 30-60 minutes (longer than endorphins due to D-Ala)
1–2 hours
Admin Route
Subcutaneous (research), Intrathecal (research), Intranasal (research)

Research
Typical Dose
Not established for human use; research doses vary widely
0.25–0.5 mg
Frequency
Not established
Once daily
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
  • Promotes skin tanning and melanin production
  • Reduces UV exposure needed to tan
  • Enhances libido and sexual function
  • May suppress appetite
  • Faster, deeper tan development
  • Longer-lasting tan maintenance
  • Potential photoprotective effects
Side Effects
