GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine coordinated to copper(II). Pickart's plasma work in the early 1970s is the historical source of the activity that was later assigned to that sequence. Laboratories use the complex as a defined ligand in matrix and gene-expression models. This page is the glossary entry. Milligrams, price, and stock stay on GHK-Cu 50 mg.
For the deepened mechanism note for the sequence, see What is GHK-Cu?. For the class page, see copper peptides. The library row for the 50 mg lot includes mass, purity, and endotoxin links when that review is current. Confirm the file you opened names this SKU.
Frequently asked questions
- Is GHK-Cu a synonym for dietary copper?
- No. It is a defined tripeptide-copper complex supplied as a research solid. It is not a finished cosmetic and it is not a copper supplement.
