Product Overview

GHK-Cu is a naturally occurring tripeptide with a high affinity for copper ions. It is found endogenously in human plasma, saliva, and urine, and has attracted significant scientific interest due to its involvement in cellular repair signaling, gene expression modulation, and extracellular matrix regulation. The capsule format presents researchers with a standardized, pre-measured oral delivery vehicle for laboratory investigation into GHK-Cu’s biochemical properties. Available to buy online from Direct Anti Peptide, these capsules are competitively priced and dispatched with full analytical documentation.

Peptide Structure & Amino Acid Sequence

GHK-Cu is a tripeptide composed of three amino acid residues: Glycine – L-Histidine – L-Lysine, chelated with a copper(II) ion (Cu²⁺). The sequence is commonly written as Gly-His-Lys·Cu²⁺. The histidine residue plays a critical role in coordinating the copper ion, forming a stable complex that influences the peptide’s biological activity in research models. The molecular formula of the GHK peptide backbone is C₁₄H₂₄N₆O₄, with the copper complex adding significant coordination chemistry relevant to redox biology and metallopeptide research.

Purity & Analytical Verification (HPLC & MS)

Every batch of GHK-Cu Capsules supplied by Direct Anti Peptide achieves a minimum purity of ≥98% as confirmed by High-Performance Liquid Chromatography (HPLC). Mass Spectrometry (MS) is additionally employed to verify molecular identity and confirm the integrity of the copper chelate complex. Researchers can rely on these analytical benchmarks when designing experiments that demand consistent, reproducible peptide concentrations. Certificates of Analysis (CoA) are available upon request and accompany all orders placed through our store.

Quality Control & Lyophilization Integrity

The active GHK-Cu peptide content within each capsule is derived from lyophilized (freeze-dried) bulk powder, a process that removes moisture under vacuum to preserve peptide structure and extend shelf stability. Lyophilization minimizes oxidative degradation and enzymatic breakdown, ensuring that the copper chelate remains intact during storage. Our quality control pipeline includes multi-point testing across synthesis, lyophilization, encapsulation, and final release stages, maintaining the highest standards of research-grade consistency.

Safety, Handling & Laboratory Precautions

GHK-Cu Capsules are supplied strictly for qualified research personnel operating within certified laboratory environments. Standard laboratory safety protocols must be observed at all times. Researchers should wear appropriate personal protective equipment (PPE), including gloves, lab coat, and eye protection, when handling any research peptide compound. This product is not intended for self-administration, human consumption, or use in any clinical or veterinary setting. Disposal must comply with applicable local and national regulations governing laboratory chemical waste.

Reconstitution, Packaging & Storage

GHK-Cu Capsules are supplied in sealed, tamper-evident containers designed to maintain product integrity during transit and storage. Capsules should be stored in a cool, dry environment away from direct light and humidity. For extended stability, storage at 2–8°C is recommended. Do not freeze the capsule format unless specifically indicated in your laboratory protocol. All packaging is designed to meet research-grade handling requirements and is clearly labeled with batch number, quantity, and purity grade for full traceability.

Intended Research Use & Market Positioning

GHK-Cu has been the subject of extensive peer-reviewed research investigating its role in collagen synthesis modulation, wound-healing signaling pathways, antioxidant gene activation, skin barrier integrity studies, and tissue regeneration models. The capsule format is particularly suited to researchers studying oral bioavailability of copper peptides, gastrointestinal stability of metallopeptide complexes, and systemic distribution in preclinical models. Direct Anti Peptide positions these capsules as a premium, competitively priced research reagent for institutions, independent laboratories, and academic research groups seeking reliable GHK-Cu supply.
