Description
Product Overview
GHK-Cu (copper peptide GHK, or glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide with a high affinity for copper(II) ions. First identified in human plasma, GHK-Cu has been extensively studied in skin biology, wound healing, and tissue remodeling research. The copper-bound form is the biologically active configuration that has generated the most research interest.
PeptixBio provides GHK-Cu in lyophilized form at research-grade purity, verified by independent HPLC and mass spectrometry analysis. Each vial includes a Certificate of Analysis.
Research Background
GHK-Cu is one of the most well-characterized copper peptides in published research. Studies have examined its role in stimulating collagen synthesis, promoting decorin production, increasing glycosaminoglycan synthesis, and modulating matrix metalloproteinase (MMP) activity. These processes are central to extracellular matrix remodeling and tissue repair.
Researchers have also investigated GHK-Cu for its antioxidant properties, including its ability to modulate superoxide dismutase (SOD), catalase, and other antioxidant enzyme systems. Published genomic studies have reported that GHK can influence the expression of numerous genes involved in tissue repair, anti-inflammatory signaling, and stem cell recruitment.
In dermatological research, GHK-Cu has been studied for its effects on skin thickness, elasticity, and barrier function. Additional research has explored its potential role in hair follicle biology, nerve regeneration, and bone tissue repair. The compounds natural occurrence in human biology and its decline with age have made it a subject of interest in aging research.

Quality Assurance
PeptixBio maintains strict quality control for all GHK-Cu inventory. Each batch is tested for purity via HPLC, confirmed by mass spectrometry, and screened for heavy metal contamination beyond the copper complex. Certificates of Analysis are included with every order.
Reconstitution and Handling
Reconstitute GHK-Cu with sterile water or bacteriostatic water in a clean laboratory environment. The reconstituted solution will have a characteristic blue color from the copper complex. Store at 2-8°C after reconstitution and use within 30 days. Keep the lyophilized powder at -20°C until ready for use. Avoid repeated freeze-thaw cycles.

Quality Standards Behind Every GHK-Cu Lot
Every lot leaving the PeptixBio facility passes independent third-party HPLC testing. The Certificate of Analysis is matched to the batch number printed on each vial. Researchers can verify the COA before opening the package, then again at the bench. This level of transparency separates research-grade supply from grey-market sources.
Storage matters as much as sourcing. Each vial ships in lyophilized form with a desiccant pack and should be stored at -20°C until reconstituted. After reconstitution, refrigerate at 2-8°C. Following these conditions preserves potency throughout the research timeline. Cold-chain handling guidance ships with every order.
