Considering 5-AMino-1MQ vs
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
