Comparison

BPC-157 vs GHK-Cu

Function

While BPC-157 is investigated for accelerating healing of gastrointestinal mucosa, tendons, ligaments, bone, and nervous tissue in preclinical models, with anti-inflammatory and pro-angiogenic effects111, GHK-Cu acts as a tissue-remodeling and wound-healing signal, enhancing skin regeneration, angiogenesis, and repair while reducing inflammation and oxidative damage in experimental models31383.

Mechanism

While BPC-157 works as a synthetic 15-amino-acid fragment of a gastric cytoprotective protein that promotes angiogenesis and tissue protection primarily by modulating VEGFR2 signaling, Src/caveolin-1–dependent eNOS activation, and nitric oxide production111, GHK-Cu is an endogenous tripeptide, Gly-His-Lys, that chelates Cu²⁺ and modulates gene expression, stimulating collagen, elastin, proteoglycan, and glycosaminoglycan synthesis while exerting antioxidant and anti-inflammatory effects31383.

Length and Sequence

BPC-157 is 15 amino acids long, whereas GHK-Cu is shorter as it has a length of 3 amino acids. BPC-157 is made up of a sequence of Glycine, Glutamic acid, Proline, Proline, Proline, Glycine, Lysine, Proline, Alanine, Aspartic acid, Aspartic acid, Alanine, Glycine, Leucine, Valine. GHK-Cu is made up of a sequence of Glycine, Histidine, Lysine.
