GHK-Cu (Topical)

Direct Anti Peptide is proud to offer GHK-Cu (Topical), a high-purity copper tripeptide complex manufactured to ≥98% purity and intended exclusively for qualified researchers and laboratory professionals. As a well-characterized reference compound in peptide science, GHK-Cu continues to attract significant attention across dermatological, regenerative, and biochemical research disciplines.

Product Overview

GHK-Cu, formally known as glycyl-L-histidyl-L-lysine copper complex, is a naturally occurring tripeptide found in human plasma, saliva, and urine. Its concentration in the body is known to decline with age, a pattern that has made it a compelling subject of study in fields concerned with skin biology, wound healing models, and cellular repair mechanisms. Researchers investigating the intersection of peptide chemistry and tissue physiology frequently select GHK-Cu as a primary reference compound due to its well-documented biochemical profile.

Peptide Structure & Amino Acid Sequence

GHK-Cu is a tripeptide composed of three amino acids: Glycine (Gly), L-Histidine (His), and L-Lysine (Lys), arranged in the sequence Gly-His-Lys. The peptide forms a stable complex with copper(II) ions (Cu²⁺), which is central to its biochemical activity in research models. This copper-chelating capability allows the compound to facilitate copper ion transport to enzymes and skin cells in controlled experimental environments. The molecular formula is C₁₄H₂₄CuN₆O₄, with a molecular weight of approximately 340.84 g/mol for the free peptide and 403.92 g/mol for the copper complex.

Purity & Analytical Verification (HPLC & MS)

Every batch of GHK-Cu (Topical) supplied by Direct Anti Peptide undergoes rigorous analytical testing to confirm ≥98% purity. High-Performance Liquid Chromatography (HPLC) is used to verify peptide identity and purity against established reference standards, while Mass Spectrometry (MS) confirms the correct molecular mass and structural integrity of the copper complex. Certificates of Analysis (CoA) are available upon request and reflect batch-specific data, ensuring full traceability for research documentation purposes.

Quality Control & Lyophilization Integrity

GHK-Cu is produced using pharmaceutical-grade synthesis protocols and subjected to multi-stage quality control procedures before dispatch. The compound is lyophilized (freeze-dried) to remove residual moisture and preserve structural stability during transit and storage. Lyophilization minimizes degradation risk and extends shelf life, making it the preferred presentation format for research-grade peptides. Each unit is sealed under inert conditions to maintain integrity from production through to laboratory receipt.

Safety, Handling & Laboratory Precautions

GHK-Cu (Topical) is a research-grade chemical compound and must be handled exclusively by trained laboratory professionals in accordance with institutional safety protocols. Appropriate personal protective equipment (PPE), including gloves, lab coat, and eye protection, should be worn at all times when handling this material. Standard laboratory biosafety and chemical handling guidelines apply. This product is not formulated, tested, or approved for any application outside of controlled research environments.

Reconstitution, Packaging & Storage

GHK-Cu (Topical) is supplied as a lyophilized powder in sealed, research-grade vials. For laboratory reconstitution, researchers should consult relevant peer-reviewed literature and institutional protocols to determine appropriate solvents and concentrations for their specific experimental design. Upon receipt, store at −20°C in a dry, dark environment away from moisture and direct light. Once reconstituted under laboratory conditions, use promptly or store according to validated in-house stability data. Repeated freeze-thaw cycles should be avoided to preserve compound integrity.

Intended Research Use & Market Positioning

GHK-Cu is one of the most extensively studied copper peptides in scientific literature, making it a preferred reference compound for researchers exploring collagen synthesis pathways, extracellular matrix remodeling, oxidative stress responses, and wound healing models.
