Humanin vs Dermorphin

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

Anti-Aging & Longevity
Humanin
Recovery & Repair
Dermorphin
Summary
Humanin is a mitochondria-derived peptide (MDP) encoded in the 16S rRNA region of the mitochondrial genome. It protects neurons and other cells from apoptosis, improves insulin sensitivity, and declines significantly with age. HNG (S14G-Humanin) is a synthetic analog with 1000x greater potency.
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.

Key Benefits
  • Neuroprotection against amyloid-beta toxicity (Alzheimer's relevance)
  • Inhibits cellular apoptosis
  • Improves insulin sensitivity
  • Reduces cardiovascular risk markers
  • Anti-inflammatory effects
  • Correlates with longevity in centenarian studies
  • Protects against ischemic injury
  • Potential cancer cell apoptosis sensitization
  • 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
  • Injection site irritation
  • Limited human safety data available
  • High addiction and dependence potential (mu-opioid agonism)
