What GHK-Cu does not do, based on the mechanistic literature, is directly block the 5-alpha reductase enzyme the way finasteride does

In laboratory and preclinical research settings, BPC-157 is studied for its role in cellular signaling, tissue integrity, and adaptive biological responses under controlled experimental conditions

BPC-157, a stable 15-amino acid pentadecapeptide derived from gastric protective factors, activates the FAK-paxillin and VEGFR2-Akt-eNOS signaling cascades that drive cellular migration, angiogenesis, and wound closure with exceptional stability under diverse physiological conditions

This unusual bell-shaped dose response curve suggests the peptide operates through mechanisms that remain effective even at very low concentrations
