Dermorphin- Summary
- Pal-GHK is the palmitoylated form of the GHK tripeptide without a copper ion. By conjugating palmitic acid to glycine-histidine-lysine, skin penetration is substantially enhanced, enabling deeper dermal collagen stimulation. It is commonly paired with Pal-GHK-Cu or GHK-Cu in anti-aging formulations.
- 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.
- Half-Life
- Extended (lipid depot in stratum corneum)
- Estimated 30-60 minutes (longer than endorphins due to D-Ala)
- Admin Route
- Topical
- Subcutaneous (research), Intrathecal (research), Intranasal (research)

- Key Benefits
- Stimulates collagen I and III synthesis in dermis
- Reduces the appearance of fine lines and wrinkles
- Improves skin elasticity and firmness
- Inhibits collagenase (MMP-1) to preserve existing collagen
- Enhances wound healing and skin repair
- Well-tolerated in anti-aging serums and creams
- 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
- Generally very well-tolerated
- Rare skin irritation at very high concentrations
- Possible formulation-dependent comedogenicity
- High addiction and dependence potential (mu-opioid agonism)
