A peptide and copper
GHK-Cu is a complex formed by a small peptide and copper. Researchers have studied its relationship with connective-tissue processes, including collagen production in fibroblast cultures. That is a basis for investigating skin and extracellular-matrix biology.
Read the study in its context
A finding in cultured cells answers a laboratory question. It does not, by itself, demonstrate that a product changes skin appearance in people. The concentration, formulation and route used in research matter when interpreting any result.
Different products are not interchangeable
A research vial is not a finished topical formulation. Evidence about one form should not be transferred to another. FDA identifies limited human safety information and potential immune-response concerns for injectable GHK-Cu preparations.
Keep quality and outcomes separate
An analytical report may describe sample identity or purity. A claim about visible skin improvement needs suitable evidence for the finished product and its intended use. The demonstration certificate in this store is a layout example only.
