ghk-cu copper coordination structure (glycyl-L-histidyl-L-lysine complex) is a naturally occurring tripeptide bound to a copper ion. It is formed by the of the peptide GHK with copper (Cu²⁺) and has been identified in Copper peptide GHK-Cu - Wikipedia

Research indicates it may help modulate dopamine and serotonin levels

VEGFR2 Pathway Studies show BPC-157 upregulates VEGFR2 mRNA and protein expression in vascular endothelial cells, promoting receptor internalization and activating downstream VEGFR2AkteNOS signaling (Hsieh et al., Journal of Molecular Medicine, 2017)
