GHK-CU - 100mg / 50mg

GHK-Cu Peptide (Glycyl-L-Histidyl-L-Lysine Copper)
 
 
GHK-Cu is a naturally occurring tripeptide copper complex formed by the amino acids glycine (Gly), L-histidine (His), and L-lysine (Lys) bound to a copper(II) ion (Cu²⁺). This small molecule has a molar mass of ~340.4 g/mol in its uncomplexed form (C₁₄H₂₄N₆O₄) and forms a stable square-planar copper chelate with high water solubility (~131 g/L). 
 
GHK-Cu exhibits multifaceted biochemical activity at physiological concentrations (picomolar to nanomolar) by modulating gene expression, cellular signalling, and extracellular matrix (ECM) dynamics. It binds copper via the imidazole nitrogen of histidine and peptide backbone nitrogens, forming a bioactive complex that influences collagen, elastin, and glycosaminoglycan synthesis. 
 
Key technical and functional features:
 
Peptide sequence: Gly-His-Lys (tri-amino acid)  
Copper complex: 1:1 ratio of peptide to Cu²⁺  
Molecular weight: ~340.38 g/mol (without Cu); complexed form ~ranges with Cu²⁺ bound  
Solubility: High aqueous solubility  
Stability: Stable at physiological pH (~6.5–7.5), can dissociate outside this range
