ActiTide-CP is a complex of glycyl histidine tripeptide (GHK) and copper. Its aqueous solution is blue. Copper peptide is the ancestor of Sheng peptide. Sheng peptide is actually small molecule protein, which is composed of amino acids. These small molecule proteins are more easily absorbed by the skin. Sheng peptide is composed of some amino acids with a specific sequence, which are connected by amide bond arrangement.
