AHK-Cu
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.
AHK-Cu is a copper tripeptide composed of alanine, histidine, and lysine chelated to copper. Distinct from GHK-Cu, AHK-Cu exhibits strong affinity for hair follicle receptors and demonstrates potent hair growth stimulation alongside wound healing and skin regeneration properties.
Half-Life

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
  • Stimulates hair follicle growth and reduces shedding
  • Increases dermal papilla cell proliferation
  • Promotes wound healing and skin regeneration
  • Antioxidant protection via superoxide dismutase activation
  • Improves skin elasticity and firmness
  • Supports collagen and elastin 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
  • Generally well-tolerated topically
  • Mild scalp irritation or redness in sensitive individuals
  • Possible temporary hair shedding phase at treatment initiation
  • Copper accumulation with excessive systemic use (rare)
