It is not for human or animal use , GHK-Cu is a laboratory research material used to examine peptide-copper interactions, signaling pathways, and gene-expression responses in controlled experimental models
We observed that only human GH preparations that are known to have a PRL-like effect were efficient in stimulating thymulin biosynthesis and release into the culture supernatants
Again, though, these actions are largely characterized in cell and animal systems, and their relevance to visible human skin change depends entirely on whether an effective concentration reaches the dermis by the route in question
