What Is GHK-Cu?
GHK (glycyl-L-histidyl-L-lysine) is a tripeptide first isolated from human plasma in 1973. It binds copper(II) with high affinity, and the resulting complex, GHK-Cu or copper tripeptide-1, is one of the most studied copper peptides in cell biology. Our GHK-Cu 100mg vial contains the copper complex with a molecular weight of approximately 403.9 Da; the blue colour of the powder is characteristic of the copper content.
The 100mg fill suits laboratories running larger cell-culture or materials studies. For an introduction to the peptide, see our guide What is GHK-Cu?, and for sourcing criteria read what serious buyers check in GHK-Cu peptide.
GHK-Cu Research Areas
Laboratory studies of GHK-Cu cover several areas of the published literature:
Extracellular Matrix Remodelling
GHK-Cu is studied in fibroblast cultures for its effects on collagen, elastin, glycosaminoglycan and decorin synthesis, and on matrix metalloproteinase balance. Published work can be explored on PubMed.
Copper Transport and Enzyme Activity
The peptide is used to investigate copper delivery to cells and its effect on copper-dependent enzymes such as superoxide dismutase and lysyl oxidase.
Gene Expression Profiling
Transcriptomic studies have examined GHK-Cu’s broad effects on gene expression in cultured cells, including genes involved in tissue remodelling and antioxidant defence.
Skin and Hair Follicle Models
GHK-Cu is widely used in dermal and follicle research; see our overview of research peptides for skin studies.
GHK-Cu vs AHK-Cu and Copper Peptide Blends
AHK-Cu is a related copper tripeptide in which glycine is replaced by alanine; it is studied more often in follicle models. GHK-Cu is also the largest component of our GLOW70 and KLOW80 blends for researchers investigating it alongside BPC-157, TB-500 and KPV.

GHK-Cu 100mg FAQs
What is GHK-Cu?
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine. It is used as a research tool in extracellular matrix, copper-transport and gene-expression studies.
Why is GHK-Cu powder blue?
The blue colour comes from the copper(II) ion bound to the peptide. A pale or colourless powder would indicate low copper content.
Does GHK-Cu 100mg need reconstituting?
Yes. It is supplied as lyophilised powder and should be reconstituted with bacteriostatic water before use in research protocols.
How is GHK-Cu 100mg tested?
Every batch is tested to ≥99% purity by HPLC, with identity confirmed by mass spectrometry, at an ISO 17025 accredited third-party laboratory.
How should GHK-Cu be stored?
Keep the lyophilised vial at −20°C for long-term storage, protected from light. Once reconstituted, refrigerate at 2–8°C and use promptly.
Is GHK-Cu 100mg for human use?
No. It is supplied strictly for in-vitro laboratory research and is not for human or veterinary use.
