GHK-Cu 50mg

Within Europe this product is supplied including bacteriostatic water; outside Europe only the peptide vial is provided. For research use only – not for human or veterinary use.   Product Overview GHK-Cu is a copper-binding tripeptide widely studied in laboratory research for its role in cellular signalling, extracellular matrix regulation and tissue-modelling pathways. This 50 mg lyophilized preparation is intended for controlled in-vitro research into peptide–metal complex behaviour and regulated biochemical signalling systems.   Peptide Overview GHK (Glycyl-L-histidyl-L-lysine) was first identified in the early 1970s during studies of plasma-derived peptides involved in tissue regulation. Subsequent research revealed its strong affinity for copper ions, forming the biologically relevant GHK-Cu complex. Between 1980 and 2025 GHK-Cu has remained a central reference compound in research focused on cellular signalling, regenerative pathway modelling and structure–function relationships of peptide–metal complexes.   Historical Background and Scientific Context Early research between 1970 and 1990 established GHK-Cu as a key signalling molecule in extracellular communication models. Its ability to form stable copper complexes contributed to its widespread adoption in laboratory studies exploring tissue remodelling, gene-expression signalling and regulated cellular responses. From 2000 onward, GHK-Cu continued to be used extensively in controlled biochemical research due to its reproducible analytical profile and well-characterised structural properties.   Structural & Molecular Characteristics • Amino-acid chain length: 3 amino acids • Peptide family: copper-binding tripeptide • Structural classification: linear peptide–metal complex • Typical molecular weight: approximately 403 Da (peptide only) • Functional domain: copper-mediated cellular signalling region   Mechanistic Focus in Research
