GHK-Cu Pre-Mixed Pen 5mg / 100mg

Product Overview

The GHK-Cu Pre-Mixed Pen available at Direct Anti Peptide represents one of the most convenient and precise delivery formats for researchers studying copper peptide biology. GHK-Cu (Glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide found in human plasma, saliva, and urine. It has attracted significant scientific interest due to its documented involvement in tissue remodelling, wound healing signalling, antioxidant defence, and anti-inflammatory cascades. Supplied at ≥98% purity, this pre-mixed cartridge system eliminates manual preparation steps, reducing variability and improving experimental consistency across research protocols.

Peptide Structure & Amino Acid Sequence

GHK-Cu is a tripeptide composed of three amino acids: Glycine – Histidine – Lysine, chelated with a copper (Cu²⁺) ion. Its molecular formula is C₁₄H₂₃CuN₆O₄ with a molecular weight of approximately 403.92 g/mol. The copper ion is coordinated through the histidine imidazole nitrogen and the terminal amine groups, forming a stable complex that is integral to its biological activity in research models. The sequence is commonly written as Gly-His-Lys·Cu²⁺, and it is this chelated structure that differentiates it from the free tripeptide in laboratory applications.

Purity & Analytical Verification (HPLC & MS)

Every batch of GHK-Cu supplied by Direct Anti Peptide undergoes rigorous analytical testing prior to release. High-Performance Liquid Chromatography (HPLC) is used to confirm a minimum purity of ≥98%, ensuring that impurities, truncated sequences, and synthesis by-products are quantified and held within strict tolerances. Mass Spectrometry (MS) validates the correct molecular weight and confirms structural integrity of the copper chelate. Researchers can rely on these verification steps to maintain data integrity across longitudinal studies and comparative assays.

Quality Control & Lyophilisation Integrity

Prior to pre-mixing, the GHK-Cu peptide is lyophilised under controlled conditions to preserve structural stability and extend shelf life. The lyophilisation process removes residual moisture without degrading the copper chelate bond, ensuring that the peptide retains full research-grade activity upon reconstitution. Each cartridge is sealed under inert conditions to prevent oxidative degradation. Batch-level quality control documentation is maintained in line with laboratory reagent standards, providing researchers with confidence in product consistency from order to order.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by trained research professionals in appropriately equipped laboratory environments. Standard laboratory personal protective equipment (PPE) — including gloves, eye protection, and lab coat — should be worn when handling peptide cartridges. Avoid direct skin contact with the pre-mixed solution. Do not expose cartridges to excessive heat, direct sunlight, or freeze-thaw cycles once mixed. All waste materials should be disposed of in accordance with local laboratory and chemical waste regulations. This compound is not evaluated for safety in humans or animals.

Reconstitution, Packaging & Storage

The GHK-Cu Pre-Mixed Pen cartridge arrives pre-mixed with bacteriostatic water, eliminating the need for manual reconstitution in the laboratory. The Pre-Mixed Cartridge and Pen Kit includes:

• 1 x Pre-Mixed Peptide Cartridge (GHK-Cu in bacteriostatic water)
• 1 x Precision Peptide Cartridge Pen
• 1 x Protective Pen Carry Case
• 3 x Pen Needle Tips

Single Mixed Cartridges are also available for researchers who already own a compatible pen device, with multi-cartridge options offering additional value. Store cartridges refrigerated at 2–8°C and protect from light. Once opened, use within the timeframe specified on the cartridge label. Do not freeze pre-mixed cartridges.

Intended Research Use & Market Positioning

GHK-Cu is one of the most extensively studied copper peptides in dermatological and regenerative biology research. Scientific literature has examined its role in stimulating collagen and glycosaminoglycan synthesis, modulating matrix metalloproteinases, and activating antioxidant gene expression pathways. The pre-mixed pen format positions this compound as an ideal research tool for laboratories investigating skin biology, wound healing models, oxidative stress, and cellular senescence. Direct Anti Peptide offers this compound in both 5mg and 100mg formats to accommodate both small-scale pilot studies and larger experimental programmes.
