Unreconstituted lyophilised GHK-Cu powder remains stable at 20C for 1224 months, but once mixed into serum or cream base, refrigeration becomes mandatory to prevent peptide degradation, copper ion dissociation, and loss of collagen-stimulating activity
GPX4 catalyzes the substrate, and the product consumes the reducing agent with the addition of enzyme reagents.The reducing agent has a maximum absorbance at 340 nm, and the GP4-specific enzyme activity can be calculated by measuring non-specific enzyme activity and total enzyme activity by adding GPX-4 inhibitor to the system
