How does GHK-Cu work?
Research overview of how GHK-Cu works at the molecular level — its proposed mechanism of action, what the published research shows, and where the gaps are.
Proposed mechanism of GHK-Cu
A naturally occurring copper-binding tripeptide researched for collagen synthesis, tissue remodelling, wound healing, and anti-aging applications.
Research on GHK-Cu focuses on how the peptide interacts with specific biological targets in vitro and in laboratory animal models. Because GHK-Cu is sold strictly for research use, the mechanism is discussed here only in the context of published scientific literature — not as any suggestion of human efficacy.
What the research literature describes
What does GHK-Cu do in research?
GHK-Cu stimulates collagen types I, III, and V, alongside elastin and proteoglycans. It is studied in the skin-regeneration, epithelial-barrier, and tissue-remodelling research literature.
What is the difference between 50mg and 100mg?
Both contain the same 99%+ purity GHK-Cu. The 100mg vial provides a larger quantity for extended research protocols.
Is GHK-Cu the same as copper peptide?
Yes. GHK-Cu is the scientific name for the copper tripeptide (Glycyl-L-Histidyl-L-Lysine Copper Complex) commonly referred to as copper peptide.
Researchers working with GHK-Cu typically combine multiple analytical techniques — HPLC for purity, mass spectrometry for identity confirmation, and sometimes NMR for structural verification — before beginning any experimental protocol.
Important research limitations
Most published research on novel peptides is preclinical: conducted in cell lines, tissue samples, or animal models. Results from preclinical research do not automatically translate to human outcomes, and no peptide sold for research use is a substitute for an MHRA-approved medicine. All Peptify products are "for research use only" per UK regulations.
