BPC-157 vs GHK-Cu
Injury-site repair research versus a copper tripeptide studied for collagen and skin remodelling.
Research use only. A summary of published literature for educational reference — not medical advice and not a guide to human use.
The short version
BPC-157 research focuses on tendon, gut and vascular healing in animals. GHK-Cu is a naturally occurring copper-binding tripeptide with decades of cell and skin research and wide use in cosmetic topicals.

01How they work
GHK-Cu delivers copper to cells and is reported to stimulate collagen and glycosaminoglycan synthesis and shift the expression of many genes toward a repair profile. BPC-157's mechanism is less defined, with angiogenic and nitric oxide pathways proposed.
02What studies measured
GHK-Cu studies report increased collagen production in fibroblasts and improved skin density and wrinkle measures in small topical trials. BPC-157 studies report healing endpoints in rodent injury models.
03Reported side effects
Topical GHK-Cu is generally well tolerated in cosmetic studies. Neither has a systematic injectable human safety dataset.
04Approval & evidence status
GHK-Cu is sold as a cosmetic ingredient. BPC-157 has no approved use.
