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.

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.

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.

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.

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.

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.
