In neuronal senescence model studies, the active ingredient of the product can cross the blood-brain barrier (and act directly on neurons in vitro), increase NAD+ levels in nerve cells, protect mitochondrial function, reduce neuronal apoptosis, and promote the synthesis and release of neurotransmitters (such as dopamine and acetylcholine), thereby improving signal transduction in nerve cells
Unlike other skin peptides targeting specific receptors, GHK-Cu works as a signaling molecule binding to discoidin domain receptors, activating fibroblasts broadly rather than targeting a single pathway
It can be either taken alone or in conjunction with other nutrients
