Open questions in the GHK-Cu field include the specific cellular targets responsible for the broad transcriptomic effects, the relationship between the copper-delivery role and the direct peptide-only effects (if any), the comparative biology of GHK-Cu and related copper-peptides in defined cellular contexts, and the translation of cell-culture and animal-model findings to clinical-research endpoints under controlled study conditions
High-quality human clinical trials are still lacking, and this peptide is not FDA-approved for any medical use

Effect of administration of color foods on liver function is shown in Table 3
Yes, preclinical studies suggest that these peptides may reduce scar formation by promoting efficient tissue regeneration and collagen production, leading to smoother recovery
