Key Takeaways GHK-Cu is a naturally occurring tripeptide-copper complex with documented roles in collagen synthesis and gene expression, but human RCT evidence remains absent as of 2026 Research-grade GHK-Cu must include HPLC purity 98%, mass-spectrometry identity confirmation, and bacterial endotoxin (LAL) testing in EU/mg Body Pharm supplies each vial with full per-lot traceability, including HPLC chromatogram, MS identity file and endotoxin result on request Published animal studies use 110 mg/kg subcutaneous dosing
At clinical doses, the peptide activates collagen synthesis, accelerates cell turnover, and modulates the inflammatory response across multiple tissue types
