What is a copper peptide?
Copper peptide is a tight molecular complex of a copper ion and a peptide (a short chain of amino acids). Only particular peptides are effective when combined with copper. The original research was done with copper peptide GHK-Cu by Dr. Picart, from Skin Bilogy. More recently he has been working on the so-called second generation copper peptides. If I recall correctly, from my brief discussion with him, the second generation peptides are supposed to be more stable and more specifically targeted for skin rejuvenation. (GHK-Cu was originally developed for wound healing.) The peptides used in producing 2nd generation CP can be isolated (according to Dr. Pickart) from hydrolysed soy protein. Dr. Pickart stated that 2nd generation CP are supported by research data but I have not been able to find any publications in peer reviewed journals. Perhaps it has to with patenting issues, or perhaps the supporting evidence remains insufficient. If 2nd generation CP are indeed effective, then one can
