copper ions. In scientific literature, it is often referred to as glycyl-L-histidyl-L-lysine copper(II). Researchers investigate GHK-Cu because of its involvement in cellular signaling, metal ion interactions, extracellular matrix biology, and protein regulation. Experimental studies frequently use GHK-Cu &#8230; <a title=\"What Is GHK-Cu Peptide?
