Overview
About GHK-Cu 50mg
GHK-Cu is a naturally occurring copper-binding tripeptide in which the sequence glycyl-L-histidyl-L-lysine (Gly-His-Lys) chelates a copper(II) ion to form a stable complex. First identified in human plasma, this small molecule has become a widely referenced compound in matrix biology because of the way its histidine and terminal amine residues coordinate copper, positioning the metal for participation in redox-sensitive processes.
In laboratory settings, researchers use GHK-Cu as a reference compound to probe how copper delivery influences fibroblast behavior, extracellular matrix turnover, and antioxidant signaling in cell-culture and other in-vitro systems. Its defined sequence and characteristic blue coloration—arising from the copper coordination—make it a convenient model for studying peptide-metal interactions and downstream gene-expression readouts under controlled conditions.
Key research areas

Working with the 50mg vial
This vial contains 50 mg of lyophilized material. Reconstitution does not change that mass — it changes the volume it occupies — so the concentration you end up with is set entirely by how much diluent you add.

Frequently Asked Questions
Why is GHK-Cu 50mg a blue powder rather than white?
The characteristic blue color comes from the copper(II) ion coordinated within the Gly-His-Lys tripeptide complex. This visible coloration is a hallmark of the intact peptide-copper coordination and distinguishes GHK-Cu from the uncomplexed GHK peptide, which is not blue.
How should researchers reconstitute and store GHK-Cu 50mg?
The lyophilized powder is soluble in water or bacteriostatic water for use in laboratory preparations. The vial should be refrigerated at 2–8°C to maintain stability. It is supplied lyophilized specifically to preserve integrity during shipping and handling.
What makes GHK-Cu a useful reference compound in matrix biology research?
Its defined Gly-His-Lys sequence and stable copper(II) coordination (~404 Da complex) make it a reproducible model for studying peptide-metal interactions, extracellular matrix remodeling, and copper-dependent redox signaling in cell-culture and other in-vitro systems.
