What is GHK-Cu?
GHK-Cu is a complex of the naturally occurring tripeptide GHK (glycyl-L-histidyl-L-lysine) bound to a copper(II) ion. GHK is present in human plasma, saliva, and urine, and its concentration declines with age — a pattern that has driven much of the research interest in its role in tissue maintenance and repair. The copper ion is central to its activity: GHK’s affinity for copper allows it to serve as a delivery mechanism for a cofactor required by the enzymes involved in building collagen and elastin.
Benefits and Uses
GHK-Cu is among the more extensively studied tripeptides in the research literature, with evidence spanning several decades of published work:
- Collagen and matrix synthesis. GHK-Cu is studied for its role in stimulating fibroblast production of collagen, elastin, glycosaminoglycans, and the proteoglycan decorin — the structural components of connective tissue.
- Tissue remodeling. Research has examined GHK-Cu’s dual role in modulating both the synthesis and controlled breakdown of matrix components, along with the metalloproteinases and inhibitors that regulate that turnover.
- Wound healing. GHK-Cu has been studied for its role in recruiting immune and endothelial cells to an injury site, and for accelerating wound healing across skin, gastrointestinal lining, and other tissue types in animal models.
- Antioxidant and gene-modulatory activity. Genomic analysis has reported that GHK influences expression of a large number of human genes, with research describing a directional pattern favoring DNA repair and antioxidant response pathways.
Most of the mechanistic and wound-healing evidence for GHK-Cu comes from cell culture and animal research spanning several decades; large-scale human clinical trials specific to the injectable research form remain limited.
How It Works
GHK-Cu’s primary mechanism centers on copper delivery: the peptide has a strong affinity for copper(II) ions and can readily obtain copper from its transport site on human plasma albumin, making it available to lysyl oxidase and other copper-dependent enzymes involved in cross-linking collagen and elastin. Research has also reported that GHK-Cu signals fibroblasts directly to increase production of these structural proteins, and modulates broader gene-expression pathways related to tissue repair and antioxidant defense.
Dosage and Administration
No standardized dosing protocol exists for GHK-Cu outside of individual study designs, and any research protocol, route, or dose is determined solely by the licensed researcher or practitioner and their institution.
For reference, one frequently cited protocol in the published literature describes a total dose of approximately 2.2 micrograms per kilogram — roughly 140 micrograms per injection in a human-scaled model, over a ten-day course. This reflects historical study design, not a recommended or current protocol.

Side Effects and Safety
In the published research, GHK-Cu is generally reported as well tolerated across cell culture, animal, and limited human study contexts. As with any copper-containing compound, excess copper exposure is a theoretical consideration with high or prolonged use, which is one reason research use should be supervised by a licensed professional. Long-term human safety data on the injectable research form specifically remains limited.

GHK-Cu in CellGenic's Protocols
Within CellGenic’s own provider protocols, KPV appears across several combined research bundles rather than as a single agent alone:
Within CellGenic’s own provider protocols, GHK-Cu is paired with BPC-157 and TB-500 for acute soft-tissue cases — sprains, tears, and back-or-shoulder presentations — and separately layered with BPC-157, DSIP, and TB-500 for long-horizon structural repair and inflammatory load reduction, rather than being studied as a single agent alone. Providers building a tissue-repair protocol can review the full pairings and their component products directly.
Providers building an immune- or inflammation-focused protocol can review the full pairings and their component products directly.
