When you buy GHK-Cu tablets from PSPeptides, you are accessing one of the most biologically active tripeptides known to science. Buy GHK-Cu tablets to research the full spectrum of copper peptide biology — from collagen modulation to gene expression reset. GHK-Cu (Glycine-Histidine-Lysine Copper) is a naturally occurring copper peptide tripeptide known for its profound role in biological signaling and tissue remodeling. Each tablet contains 2mg of GHK-Cu and is formulated specifically for oral use, making it one of the most accessible and research-friendly copper peptide formats available. To explore the full science of GHK-Cu, see the complete GHK-Cu research guide.
Researchers who buy GHK-Cu tablets from PSPeptides gain access to a rigorously tested, oral-safe copper peptide at the most competitive purity standard in the industry. Each unit of buy GHK-Cu tablets is backed by a batch-specific COA and full traceability documentation. See the peptide stacking guide for information on combining GHK-Cu tablets with other research peptides.
Detailed Mechanism of Action
GHK-Cu works primarily through its copper-binding capacity, which facilitates a cascade of downstream cellular and molecular events. When copper ions are chelated by the GHK tripeptide (Glycine-Histidine-Lysine), the complex becomes biologically active and can interact with cell surface receptors, modulating gene expression related to tissue repair and regeneration. This copper-peptide complex has been shown to influence over 4,000 human genes, a remarkable breadth of biological activity for a simple tripeptide.
One of the most well-characterized mechanisms involves GHK-Cu’s ability to activate TGF-beta signaling, which in turn upregulates fibroblast activity and stimulates collagen types I, II, and III production. The peptide also enhances metalloproteinase activity, allowing for controlled breakdown of damaged extracellular matrix proteins and replacement with healthy new tissue — a process essential to wound healing and anti-aging research. This dual action of building and remodeling connective tissue makes GHK-Cu tablets especially valuable in dermatology and tissue engineering studies.
Additionally, GHK-Cu has been shown to modulate VEGF (vascular endothelial growth factor), promoting new blood vessel formation (angiogenesis) that supports tissue oxygenation and nutrient delivery. Through NF-κB inhibition, it simultaneously helps reduce inflammation, creating a dual pro-healing, anti-inflammatory environment. Oral delivery of GHK-Cu tablets provides researchers with a convenient, non-invasive administration format that opens new experimental paradigms for systemic peptide research.
GHK-Cu’s influence on antioxidant defenses is another exciting research frontier — the peptide upregulates superoxide dismutase (SOD) and catalase enzymes, strengthening cellular defenses against oxidative stress.

Published Research Highlights
GHK-Cu is among the most cited peptides in dermatological and regenerative research literature. A landmark 2015 study by Pickart and Margolina documented GHK-Cu’s activation of over 4,000 human genes, revealing its extraordinary range as a biological signaling molecule. The research demonstrated upregulation of genes linked to collagen synthesis, anti-inflammatory responses, and nerve regeneration, all from a single tripeptide-copper complex. This study set the stage for ongoing GHK-Cu oral delivery research. Reference: Pickart & Margolina, 2015, Organogenesis (PubMed 25741399).
A 2018 animal study published in the Journal of Peptide Science examined oral bioavailability of copper-chelating peptides and found favorable intestinal absorption rates, supporting the viability of oral GHK-Cu tablet formulations for systemic research. Separately, multiple topical GHK-Cu studies have confirmed its ability to increase skin density, reduce wrinkle depth, and improve elasticity following just 4-8 weeks of application — suggesting significant potential for the oral administration route. Additional research insights are available in the GHK-Cu topical serum guide. For regulatory context on research peptides, see this NIH review on bioactive peptides and oral delivery (PubMed 33126057).
GHK-Cu’s utility in longevity research has also gained traction, particularly in the context of DNA repair gene activation. Studies have shown that GHK-Cu resets the gene expression profile of aged cells toward a younger phenotype, a finding with enormous implications for anti-aging research.
