GHK-Cu 100 mg

Buy GHK-Cu 100 mg for laboratory research, supplied as lyophilized powder in one boxed 3 mL vial.

GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, abbreviated Gly-His-Lys or GHK. The supplied complex is identified by CAS 89030-95-5. Research with the complex includes studies of collagen synthesis and extracellular-matrix remodeling in fibroblast cultures.

Choose the copper complex and vial amount

The 100 mg label describes the complete peptide-copper complex, including the copper. It does not mean 100 mg of copper alone or 100 mg of copper-free GHK. Compare the GHK-Cu 50 mg presentation if your laboratory requires another package size; the analytical records still need to match the selected item and lot.

Copper-free GHK and GHK-Cu are different materials. The neutral 1:1 copper-complex reference has formula C14H22CuN6O4 and molecular weight approximately 401.91 g/mol. This reference value includes copper; the 340.38 g/mol value for copper-free GHK does not. Molecular weight identifies a reference chemical form, while the vial label states the amount supplied.

This powder is a laboratory material, not a ready-made cosmetic serum or cream. The vial’s 3 mL capacity also does not specify a supplied solution volume or concentration.

What fibroblast studies found

In a 1988 collagen-synthesis study, investigators reported increased collagen production in fibroblast cultures exposed to the GHK-copper complex. The response was independent of a change in cell number. That distinction matters: more collagen in the measured system did not simply mean more cells.

Matrix production and matrix remodeling

A 2000 study of cultured dermal fibroblasts examined MMP-2, an enzyme involved in extracellular-matrix remodeling. GHK-Cu increased MMP-2 levels in the culture medium and its messenger RNA. Copper ions reproduced the MMP-2 effect, while copper-free GHK did not.

The investigators also reported increased secretion of TIMP-1 and TIMP-2, inhibitors of matrix metalloproteinases. These separate measurements show why matrix production, enzyme expression and remodeling should not be collapsed into a single promise of tissue repair. They are cell-culture observations, not evidence of skin, hair or anti-aging results from this vial.

Certificate of analysis and product documents

Use COA & Documents to review the available batch reports and product files. Match the material, presentation and lot. Identity, chromatographic purity and measured content are different analytical properties; inspect the methods and results actually reported.

Confirm storage, solvent compatibility and prepared-solution stability for the supplied material and your assay. A general handling guide does not establish those specifications or a universal shelf life.
