First isolated from human plasma in the 1970s, GHK-Cu is one of the most extensively studied copper peptides in the dermatology, regenerative biology and gene-expression literature. Optic Labs supplies GHK-Cu as a high-purity lyophilised powder in 50mg and 100mg vials, packaged for in vitro and preclinical laboratory research. Each batch is independently HPLC-tested for purity and identity, with certificates of analysis available on request.\u003c\/p\u003e\n\n\u003cp\u003ePublished research has investigated GHK-Cu in models of collagen and elastin synthesis, fibroblast activity, antioxidant gene expression, copper transport, and skin-regeneration signalling.

GHK-Cu refers to the same tripeptide bound to a divalent copper ion.

This is normal and expected for a properly formulated GHK-Cu complex.
