Produced via solid-phase peptide synthesis with subsequent copper complexation, GHK-Cu is associated with matrix metalloproteinase regulation and growth factor signalling pathways
ROS and RNS may trigger programmed cell death, e.g., apoptosis [29], necessary for tissue remodeling during the development and normal tissue turnover [30], proliferation, differentiation, maturation of neural stem cells, dendritic processes, and synaptic plasticity [31,32,33]
These results suggest copper peptides work best as part of a stack not as a sole therapy for moderate-to-severe pattern hair loss
