A naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with copper) — studied in the context of tissue and wound-repair, anti-inflammatory and antioxidant, and collagen and skin research.
Independently 8× tested by a US ISO/IEC 17025 lab.
GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with copper). It has been studied in the scientific literature in the context of tissue and wound-repair research, anti-inflammatory and antioxidant research, and collagen and skin research.
Each batch of GHK-Cu is tested by a U.S.-based, ISO/IEC 17025-accredited laboratory across the following verification protocols.
Identity Confirmation
Compound-specific chromatographic fingerprinting (HPLC) that matches sample retention time and peak profile against certified reference standards, verifying the sample matches the expected compound.
Purity Analysis (≥99% by HPLC)
High-performance liquid chromatography profiling to confirm purity of 99% or greater.
Sterility Screening
Microbial contamination testing on multiple vials per lot, using a DNA-based microarray platform for rapid detection of a broad panel of contaminants to confirm the absence of microbial growth under validated laboratory methods.
Endotoxin Assessment (USP <85>)
Kinetic chromogenic LAL screening for bacterial endotoxin quantitation, performed on multiple vials per lot as an added contamination control beyond microbial testing. Results are reported in EU/mg with full method documentation on the Certificate of Analysis.
Heavy Metal Analysis (ICP-MS)
Multi-element screening for trace elemental contaminants and residual metals introduced during solid-phase peptide synthesis (including arsenic, cadmium, lead, mercury, and chromium), performed by ICP-MS in accordance with ICH Q3D elemental impurity guidelines.
Conformity Verification
Confirmation of consistent purity and content across multiple vials per lot, ensuring uniformity and reproducibility throughout each lot.
Fill Weight Confirmation
Net content verification to confirm lot consistency.
Fentanyl Screening
Contamination testing to verify that research compounds and peptides are free of fentanyl.
