The practical reason to read "Sermorelin vs GHK-Cu: Which Is Better?" is to separate useful context from easy claims about the main claim, safety boundary, and next practical step

That timeline assumes GHK-Cu is being used alongside a physical hair restoration treatment: PRP, exosomes, or microneedling with exosomes

These findings have generated significant research interest in the compound as a tool for investigating HGF/c-Met-associated signaling networks, synaptic regulatory processes, and molecular pathways governing neuronal connectivity

Delivery method determines outcome

GHK-Cu stimulates angiogenesis primarily through upregulation of key growth factors including vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF/FGF-2), with research demonstrating that GHK-Cu at nanomolar concentrations increases VEGF expression in dermal fibroblasts and stimulates human umbilical vein endothelial cell (HUVEC) proliferation through enhanced VEGF and FGF-2 expression
