Mechanism of action — research context
GHK-Cu is a naturally occurring copper peptide studied for regenerative signaling. Research examines its activation of genes involved in collagen synthesis, tissue remodeling, wound-healing pathways, and antioxidant defense, plus its role in inflammation modulation and vascular-repair signaling.
Frequently asked questions
GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine bound to a copper(II) ion, forming a stable copper complex. It's naturally present in human plasma and is one of the longest-studied peptides in the research literature.
Research centers on extracellular-matrix signaling — collagen and elastin gene activation, fibroblast activity, antioxidant enzyme expression, and wound-model tissue remodeling — largely driven by its copper-delivery chemistry rather than the peptide backbone alone.
Each batch is analyzed by RP-HPLC and mass spectrometry, with copper-complex integrity confirmed alongside standard purity and identity testing, and results published on an independent, batch-specific certificate of analysis.
As a lyophilized powder, keep it refrigerated and shielded from light prior to reconstitution; once reconstituted for laboratory use, store refrigerated and use within the compound's stability window to preserve the copper-complex integrity.
