GHK-Cu 50mg

GHK-Cu 50 mg

Buy GHK-Cu 50 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 50 mg label describes the complete peptide–copper complex, including the copper. It does not mean 50 mg of copper alone or 50 mg of copper-free GHK. Compare the GHK-Cu 100 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.
