Gene Expression ECM Remodeling Copper Signaling Mechanism of Action Primary TGF- / Collagen / LOX Extracellular Matrix Remodeling GHK-Cu upregulates collagen I, collagen III, and decorin synthesis in fibroblast cultures

It shifts macrophages from M1 (pro-inflammatory) to M2 (reparative) phenotype and inhibits excessive NF-kB activation

This angiogenic effect explains much of why BPC-157 works so broadly: better blood supply to injured tissue accelerates virtually every downstream repair process

The focus of preclinical studies has shifted from investigating glucose metabolism alone to exploring more complex mechanisms, such as the metabolic interplay between Schwann cells and axons and the role of insulin resistance in nerve function
