Dermorphin vs AOD-9604

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

Recovery & Repair
Dermorphin
Fat Loss & Metabolic
AOD-9604
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.
AOD-9604 is a modified fragment of human growth hormone (residues 177-191) with an additional tyrosine residue that significantly enhances bioavailability. Originally developed as an anti-obesity drug by Metabolic Pharmaceuticals, it stimulates lipolysis and inhibits lipogenesis without the diabetogenic effects of full GH.

30-45 minutes injectable; longer with nasal spray formulation
Admin Route
Subcutaneous (research), Intrathecal (research), Intranasal (research)
SubQ, Intranasal, Oral
Research
Typical Dose
Not established for human use; research doses vary widely
300-600 mcg
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
  • Selective fat loss without anabolic side effects
  • No effect on blood glucose or insulin resistance
  • Improved bioavailability over Fragment 176-191
  • GRAS (Generally Recognized As Safe) status in Australia
  • Potential cartilage repair and anti-inflammatory properties
  • Does not suppress natural GH production
Side Effects
  • High addiction and dependence potential (mu-opioid agonism)
  • Respiratory depression at high doses
  • Nausea, vomiting, constipation
  • Sedation and cognitive impairment
  • +2 more
  • Localized injection site reactions
  • Headache (rare)
  • Hypoglycemia risk in combination with insulin (very rare)
