Pal-AHK
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.
Pal-AHK is the palmitoylated form of the AHK-Cu copper tripeptide, created by attaching a palmitic acid chain to enhance skin penetration and lipid bilayer affinity. The palmitoyl modification significantly improves dermal bioavailability compared to unmodified AHK, making it particularly effective in anti-aging and hair growth formulations.
Half-Life
Estimated 30-60 minutes (longer than endorphins due to D-Ala)
Extended (lipid depot effect in stratum corneum)
Admin Route
Subcutaneous (research), Intrathecal (research), Intranasal (research)
Topical

Typical Dose
Not established for human use; research doses vary widely
0.01–0.05% in formulation
Frequency
Not established
Once or twice 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
  • Enhanced skin penetration vs. unmodified AHK-Cu
  • Stimulates dermal collagen and elastin production
  • Promotes hair follicle anagen phase
  • Antioxidant and wound healing activity
  • Firming and plumping effect on aging skin
  • Improved bioavailability via lipid bilayer incorporation
Side Effects
  • High addiction and dependence potential (mu-opioid agonism)
  • Respiratory depression at high doses
  • Nausea, vomiting, constipation
  • Sedation and cognitive impairment
  • +2 more
  • Generally well-tolerated
  • Mild irritation at high concentrations in sensitive skin
  • Possible comedogenicity at very high palmitate concentrations (formulation-dependent)
