GHK-Cu 50mg

Research applications

• Dermal fibroblast behaviour and collagen synthesis research
• Copper-binding peptide chemistry and metal coordination studies
• Gene expression research on tissue-remodelling pathways
• Cellular ageing research (age-related decline in endogenous GHK-Cu)

What the literature reports on GHK-Cu

GHK-Cu was first identified as a component of human plasma, and subsequent research reported that its concentration declines substantially with age, a finding that positioned it within cellular-ageing and dermal-biology research programmes. Its copper-coordination chemistry, mediated primarily through the histidine imidazole group, has been characterised in detail in the peptide chemistry literature.

Dermal fibroblast research

In vitro studies using cultured dermal fibroblasts have reported that GHK-Cu exposure is associated with changes in collagen and glycosaminoglycan production, extracellular matrix components central to skin structure. This research has extended to studies of fibroblast migration and proliferation in wound-healing cell models.

Gene expression research

Gene-expression profiling studies have reported that GHK-Cu exposure influences the transcription of genes associated with tissue remodelling and antioxidant defence pathways in cultured cells, research that has been used to propose broader mechanistic models for GHK-Cu's reported cellular effects.

Copper chemistry research

As a well-characterised copper-binding tripeptide, GHK-Cu is also studied within bioinorganic chemistry research examining metal-peptide coordination, with structural studies describing the geometry of copper binding at the histidine imidazole and adjacent backbone nitrogens.

Nomenclature and identity research

Researchers should note that the CAS registry numbers used across commercial sources for GHK-Cu are not fully consistent: some sources register the number to the free, uncomplexed GHK tripeptide rather than to the copper complex itself. Analytical verification of the copper-bound state, rather than reliance on a single CAS number, is recommended practice when identity confirmation is required for a given research protocol.

Comparative longevity-research context

Within this catalogue's GLOW category, GHK-Cu is studied for its dermal and cellular effects as distinct from the telomerase-focused research associated with Epithalon, and the two compounds are sometimes examined in parallel within broader cellular-ageing research programmes.

Laboratory handling

GHK-Cu should be stored as lyophilised powder at -20°C, protected from light and moisture, until reconstitution. Because the copper complex is more chromophoric and redox-sensitive than uncomplexed peptides, minimising light exposure during handling is particularly important for preserving the intact complex.

• Lyophilised powder: store at -20°C, protected from light, until reconstitution.
• Reconstitution: introduce diluent slowly along the vial wall; mix gently, do not shake.
• Post-reconstitution: 2-8°C for short-term laboratory use, protected from light; avoid repeated freeze-thaw cycles.
• Each batch ships with a certificate of analysis confirming ≥99% purity by HPLC and identity by mass spectrometry.
