GHK- 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 is the natural tripeptide (Gly-His-Lys) released from human albumin that activates tissue remodeling, collagen synthesis, and anti-aging gene expression. The copper-free form is the biological signaling molecule; it chelates copper in tissue to form GHK-Cu but also has independent biological activity.
- Half-Life
- Estimated 30-60 minutes (longer than endorphins due to D-Ala)
- Extremely short as free peptide; tissue binding extends local effects
- Admin Route
- Subcutaneous (research), Intrathecal (research), Intranasal (research)
- SubQ, Topical, Oral
