GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine) complexed with copper(II), supplied as a lyophilised powder. It is supplied strictly for laboratory research use only.

What research area is GHK-Cu associated with?

Published preclinical laboratory work in this class concerns copper-ion transport chemistry and gene-expression signalling in cell culture. We supply the material only; we make no representation as to any outcome, effect, or suitability for any purpose.

Is GHK-Cu approved for human use?

No. GHK-Cu is not a drug, supplement, food, cosmetic, or medical device, and has no approved human or veterinary indication. It is sold strictly for in-vitro laboratory research use by qualified professionals.

What purity is GHK-Cu supplied at, and how is it verified?

Each lot is assayed by HPLC and ships with its own lot-specific Certificate of Analysis, published in our COA registry. Purity figures are stated per lot - we do not publish a brand-wide specification in place of the actual certificate.

Proof, not promises. Every batch, tested by an outside lab.

Every batch of GHK-CU is tested by an outside lab before it goes on sale — not by us. The one shipping now is lot JBG0GP: 99.80% pure by HPLC, tested by Freedom Diagnostics on 14 Sept 2026. The signed report is right here. Purity is the number the lab measured, never “at least 99” — and a batch that misses its spec never ships.

What the studies found

Published findings on this compound, each linked to its source. Animal and lab results are context, not claims about this product.

Younger gene patternsPreclinical

4,000+

In gene-expression analyses, GHK has been reported to shift the activity of at least 4,000 human genes, many of them toward a more youthful pattern.

toward younger expression

BioMed Research International, 2015 · gene-expression review

4,000+ genes

genes shifted

Human gene-expression analyses; collagen-synthesis pathways upregulated.

Wound healingPreclinical

In a mouse scald-wound model, GHK-Cu–liposome-treated wounds closed faster than untreated ones, alongside more cell growth and new blood-vessel formation.

vs untreated wounds

Untreatedslower closure

GHK-Cufaster closure

Relative wound-closure rate; driven by proliferation and angiogenesis.

Wound Repair & Regeneration 2017

Lung scarringPreclinical

In mice with bleomycin-induced lung fibrosis, GHK-Cu was reported to reduce scarring markers, apparently through anti-oxidative and anti-inflammatory pathways.

vs untreated mice

Untreatedmore fibrosis

GHK-Culess fibrosis

Directional: relative fibrosis markers, no single reported figure.
