GHK-Cu
GHK-Cu is a natural copper peptide that occurs in human plasma. It has been widely investigated in cellular biology, structural biology, and wound healing processes in controlled laboratory conditions.
About GHK-Cu
GHK-Cu is a tripeptide-copper compound formed from glycine, histidine, and lysine, bound with copper ions (Cu²⁺). The natural occurrence of GHK-Cu in human plasma occurs in reduced levels as one ages, rendering the compound highly researched in cellular biology studies.
GHK-Cu has been highly studied because of its ability to stimulate collagen synthesis, antioxidative enzymes activation, and regulation of gene expressions in vitro experiments. The peptide is one of the most documented compounds in the field of structural and cellular biology.
