What is GHK-Cu?
GHK-Cu is a copper-binding tripeptide — glycyl-L-histidyl-L-lysine — complexed with copper(II). It occurs naturally in human plasma, and its concentration falls measurably with age, from roughly 200 ng/ml in early adulthood to around a third of that by the seventh decade. That decline is what first drew research attention to it.
The copper is not incidental: the peptide is a carrier, and much of its studied activity depends on the metal it delivers. It is supplied as a lyophilized powder — see the reconstitution guide and the reconstitution calculator for preparation.
Research context
GHK-Cu is examined for copper transport, extracellular-matrix remodelling, and an unusually broad influence on gene expression — published transcriptome work associates it with the modulation of a large number of human genes related to tissue repair and antioxidant response, which is rare for a molecule of three residues.
In repair-focused designs it is studied alongside BPC-157 and TB-500; our BPC-157 vs. TB-500 comparison covers how those two differ. GHK-Cu is also a component of the GLOW and KLOW blends, and is available in a topical aloe-based format for surface-application work.
Purity and third-party testing
Every batch is independently analysed by Testides and Peptide Test Canada and ships with a certificate of analysis reporting high-performance liquid chromatography purity and mass-spectrometry identity. See how to read a certificate of analysis and what a purity figure actually means; our process is on the Research and Quality page.
Handling and storage
The copper complex gives GHK-Cu its characteristic blue colour, and it is light-sensitive — keep it dark as well as cold. The storage guide covers lyophilized and reconstituted states, and bacteriostatic vs. sterile water explains why bacteriostatic water suits a vial sampled repeatedly.
