GHK-Cu vs BPC-157
GHK-Cu and BPC-157 are both prominent in tissue-repair and regeneration research, but they differ in structure and mechanism. GHK-Cu is a copper-binding tripeptide studied for skin and remodeling pathways, while BPC-157 is a gastric-derived peptide studied for angiogenesis and broader tissue repair. They are among the most-studied peptides in their respective areas.
