For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

GHK-Cu is one of the most extensively studied endogenous copper-chelating tripeptides in modern peptide biochemistry. As a naturally occurring molecular signal, it has attracted significant scientific interest across disciplines including regenerative biology, cellular longevity research, and systemic tissue remodeling. The Peptide Store offers this compound in a specialized 60-capsule configuration, purpose-built to support multi-unit, longitudinal in vitro and ex vivo research protocols requiring consistent, pre-measured dosing units. This format eliminates the preparation variability associated with raw lyophilized powders and allows researchers to assess encapsulated delivery mechanics with precision.

Peptide Structure & Amino Acid Sequence

GHK-Cu is a tripeptide composed of three amino acid residues: Glycine – L-Histidine – L-Lysine, complexed with a divalent copper ion (Cu²⁺). The histidine residue serves as the primary copper-coordination site, while the flanking glycine and lysine residues confer structural stability and aqueous solubility. The Cu²⁺ ion is chelated within the peptide backbone, forming a stable square-planar coordination complex. This unique architecture enables GHK-Cu to function as a selective copper carrier, regulating localized copper bioavailability within experimental systems without inducing cytotoxic copper accumulation. The tripeptide sequence is represented as: H-Gly-His-Lys-OH · Cu²⁺.

Purity & Analytical Verification (HPLC & MS)

Every batch of GHK-Cu Capsules supplied by The Peptide Store is independently verified to achieve a minimum purity of ≥98% as determined by high-performance liquid chromatography (HPLC). Complementary mass spectrometry (MS) analysis confirms precise molecular weight and structural identity, ruling out degradation products, synthetic byproducts, or copper dissociation artifacts. Certificate of Analysis (CoA) documentation is available upon request, providing full traceability for GLP-aligned and institutional research environments. Researchers can order with confidence knowing that each capsule unit delivers a consistent, analytically validated quantity of active compound.

Quality Control & Lyophilization Integrity

Prior to encapsulation, the GHK-Cu active pharmaceutical ingredient undergoes lyophilization under controlled atmospheric conditions to preserve structural integrity, copper coordination geometry, and long-term stability. The lyophilization process removes residual moisture to levels below critical degradation thresholds, ensuring that each encapsulated unit retains full biochemical activity throughout its shelf life. Post-encapsulation quality control steps include capsule weight uniformity testing, moisture content assessment, and visual inspection for fill consistency. Only batches meeting all internal release specifications are approved for sale through The Peptide Store.

Safety, Handling & Laboratory Precautions

GHK-Cu Capsules are supplied exclusively as a research reagent and must be handled in accordance with standard laboratory safety protocols. Researchers should wear appropriate personal protective equipment (PPE), including nitrile gloves, eye protection, and lab coats when handling. Capsules should not be opened, dissolved, or otherwise manipulated outside of a controlled laboratory environment. This compound is not approved for administration to humans or animals under any circumstances. All waste materials should be disposed of in compliance with applicable institutional and governmental regulations governing peptide research reagents.

Reconstitution, Packaging & Storage

GHK-Cu Capsules are supplied in solid-dose encapsulated form and require no reconstitution for standard analytical or cell-culture-based research workflows. For applications requiring aqueous solution, capsule contents may be dissolved in sterile phosphate-buffered saline (PBS) or similar aqueous buffer within a laboratory setting under appropriate containment. Store capsules at −20°C in a sealed, light-protected container to maintain maximum stability. Avoid repeated freeze-thaw cycling. When stored correctly, product integrity is maintained for the duration of the indicated shelf life as stated on the CoA. Packaging is designed for secure international transit and long-term cold-chain storage compatibility.

Intended Research Use & Market Positioning

GHK-Cu Capsules are positioned as a premium solid-dose research tool for laboratories investigating oral bioavailability modeling, gastrointestinal peptide stability, copper-mediated cellular signaling, and systemic tissue remodeling mechanisms. The encapsulated matrix format provides a reproducible, unit-dosed platform that simplifies multi-timepoint experimental designs and reduces inter-assay variability. This product is not intended for use as a dietary supplement, therapeutic agent, or clinical research material.
