ghk cu with zinc thymulin ghk-cu Copper peptides (GHK-Cu) have been studied for decades for their role Copper Peptide Serum for Scalp – ghk-cu zinc thymulin Copper peptides

Immediate receptor binding (seconds to minutes), intracellular signaling cascade propagation (minutes to hours), gene expression changes (hours to days), protein synthesis and accumulation (days to weeks), cellular and tissue-level effects (weeks to months)

The reasoning usually goes something like this: NAD+ supports metabolism

There are theoretical concerns, like a potential connection to cancer, that can't be dismissed without more research
