GHK-Cu
GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine. The free peptide and the copper complex are different catalogue entries.
Research summary only. Not medical advice, not a protocol, and not for human or veterinary consumption.
- Also called
- Copper tripeptide-1, Glycyl-histidyl-lysine copper
- CAS
- 89030-95-5
- Sequence or structure
- Gly-His-Lys, complexed with copper(II)
- Evidence
- Limited human research
Mechanism
GHK is found in human plasma and declines with age. In experimental systems the copper complex has been studied for effects on collagen, metalloproteinases, and wound models. Binding copper is part of the identity of this listing.
Evidence
There is a mixed literature of cell, animal, and small human or cosmetic studies. That is a different standard from an approved drug. The free tripeptide is commonly indexed as CAS 49557-75-7; the copper complex is commonly indexed as CAS 89030-95-5.
Limitations
Do not treat a cosmetic study as a clinical indication. Copper content and peptide content are both part of the mass. Not for human consumption via this catalogue.
