Description

GHK-Cu copper peptide research material is supplied for laboratory and non-clinical investigation of GHK-Cu (Copper Tripeptide-1), a naturally occurring copper-binding tripeptide studied extensively in dermal and connective-tissue research models.

What Is GHK-Cu

GHK-Cu is a tripeptide composed of glycine, histidine, and lysine complexed with a copper(II) ion, first identified as a naturally occurring component of human plasma. GHK-Cu copper peptide research material is used by laboratories investigating copper-dependent enzymatic activity, extracellular matrix remodeling, and wound-healing pathway mechanisms across in vitro and animal-model research systems.

Research Applications (laboratory / non-clinical research only)

• In vitro studies of fibroblast activity and collagen and elastin synthesis pathways
• Animal model research into dermal matrix remodeling and wound-closure mechanisms
• Preclinical investigation of copper-dependent antioxidant enzyme pathways
• Comparative research into copper peptide influence on angiogenesis-related signaling
• Cell culture studies examining anti-inflammatory pathway markers

Quality & Sourcing

GHK-Cu copper peptide research material is manufactured to high purity standards and verified by HPLC (High-Performance Liquid Chromatography) analysis. Each batch is lyophilized for stability, and a Certificate of Analysis (COA) is available on request confirming peptide identity and purity. Material is intended for use by qualified researchers in controlled laboratory environments only.

Supplied As

Supplied as a lyophilized 100mg vial, suitable for standard laboratory reconstitution procedures performed by trained personnel for research purposes.

Molecular Characteristics

GHK-Cu is a tripeptide consisting of glycine, histidine, and lysine coordinated to a copper(II) ion, a structure first characterized as a naturally occurring component of human plasma. This small size relative to longer synthetic peptides makes GHK-Cu relatively straightforward to synthesize and formulate, and the copper coordination is reported in the literature to confer a degree of stability against oxidative degradation compared to uncomplexed tripeptides. Material is supplied as a lyophilized powder to preserve this structure prior to laboratory use.

Handling & Storage Considerations

Lyophilized GHK-Cu should be stored in a freezer (-20°C or below), protected from light and moisture, until the researcher is ready to reconstitute the material. Once reconstituted with bacteriostatic water, the solution is generally stored refrigerated (2-8°C) and used within a window supported by internal stability testing. As with other copper-binding peptides, researchers generally avoid repeated freeze-thaw cycles and prolonged exposure to light, both of which are associated with reduced peptide integrity over time.

Common Research Design Considerations

Laboratories investigating GHK-Cu commonly design in vitro studies using fibroblast culture models to assess collagen and elastin synthesis pathways, alongside biochemical assays evaluating antioxidant enzyme activity. Animal-model research in the published literature has examined dermal matrix remodeling and wound-closure mechanisms using topical or localized administration protocols in rodent models. Comparative research designs frequently evaluate GHK-Cu alongside related copper-binding tripeptides such as AHK-Cu to characterize sequence-dependent differences in receptor and pathway engagement.

Frequently Asked Questions

Is this compound stable at room temperature?
Short-term handling at room temperature during active laboratory use is generally acceptable, but extended storage at room temperature is not recommended. Frozen storage is preferred between research sessions.

What purity level should researchers expect?
Material is verified by HPLC analysis at the time of batch testing, with purity data available via the accompanying Certificate of Analysis.

Is a Certificate of Analysis provided?
Yes, a COA is available on request for each batch, confirming identity and purity for research documentation purposes.

Related Compounds

Researchers investigating GHK-Cu often also study AHK-Cu, a related copper-binding tripeptide, in comparative laboratory research examining copper-dependent signaling pathways in dermal and connective tissue models. Some laboratories also include GHK-Cu in broader panels alongside other dermal and connective-tissue research peptides to compare relative activity across compound classes. GHK-Cu is also frequently discussed alongside TB-500 and BPC-157 in broader tissue-repair research stacks.
