GHK-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.
- GHK-Cu is a naturally occurring copper complex that declines with age. It is one of the most studied anti-aging peptides, known for powerful skin rejuvenation, wound healing, and tissue remodeling effects.
- Half-Life
- Estimated 30-60 minutes (longer than endorphins due to D-Ala)
- 2–4 hours
- Admin Route
- Subcutaneous (research), Intrathecal (research), Intranasal (research)
- SubQ, Topical
