GHK-Cu works as a powerful signaling agent
However, significant challenges remain, including the synthesis of stable tripeptides with good tissue penetration, insufficient understanding of their mechanisms of action, the scarcity of studies in larger animal models and human trials, and the lack of direct head-to-head comparisons with larger peptides [75, 95]
However, topical products often contain additional ingredients that may cause reactions independent of the copper peptide itself
much of the underlying GHK work is in vitro and animal)
