Copper Peptide

GHK-Cu

Copper Tripeptide Complex

GHK-Cu is the copper-binding tripeptide Gly-His-Lys complexed with copper(II), a naturally occurring molecule whose plasma levels decline with age. The copper complex is central to its activity and the reason it is studied differently from non-metal peptides.

In vitro research examines extracellular-matrix remodeling, collagen and glycosaminoglycan synthesis, copper-ion transport, antioxidant response, and modulation of genes associated with tissue repair. It is a frequent reference compound in skin, wound-model, and copper-peptide research, and appears as the copper-donating component of the Glow and Klow blends. Its distinguishing feature is the copper ion itself, which participates directly in the redox and matrix pathways under study. Supplied as a lyophilized 10-vial kit in 50mg and 100mg sizes for in vitro research use only.

Common Questions

GHK-Cu FAQ

What is GHK-Cu?+
GHK-Cu is a Copper Tripeptide Complex supplied for laboratory research. Copper-binding tripeptide studied in vitro for extracellular matrix signaling, collagen synthesis pathway analysis, and anti-inflammatory response mechanism research.
How does GHK-Cu work?+
GHK-Cu is a copper-binding tripeptide (Gly-His-Lys plus a copper ion) studied for its role in extracellular-matrix and collagen-synthesis signaling and in antioxidant response.
What is the difference between GHK and GHK-Cu?+
GHK is the tripeptide Gly-His-Lys on its own; GHK-Cu is that same peptide bound to a copper(II) ion. The copper-bound complex is the form most studied for extracellular-matrix, collagen-synthesis, and antioxidant signaling.
What is lyophilized GHK-Cu, and how is it reconstituted?+
GHK-Cu is supplied as a lyophilized (freeze-dried) powder, a dehydrated form that keeps the peptide stable during shipping and storage. In the laboratory it is reconstituted (returned to liquid form) using a solvent such as bacteriostatic water, added slowly against the side of the vial, which is then swirled gently, never shaken, until the powder fully dissolves. All handling is for in vitro research use only.
How should GHK-Cu be stored?+
Store the lyophilized GHK-Cu powder at -20°C, protected from light and moisture, where it remains stable long-term. Once reconstituted, keep it refrigerated (2-8°C) and use it within the timeframe appropriate for your research protocol.
What is the purity of GHK-Cu, and how is it tested?+
Every batch of GHK-Cu is produced to a purity of 99% or higher. Purity and molecular identity are verified using standard analytical methods: high-performance liquid chromatography (HPLC) to measure purity, and mass spectrometry (MS) to confirm the peptide's molecular weight.
