The full assay panel, per batch
Each batch of GHK-Cu is tested by a U.S.-based, ISO/IEC 17025-accredited laboratory across the following verification protocols.
Identity Confirmation
HPLC fingerprinting matching retention time and peak profile against certified reference standards to confirm identity.
Purity Analysis (≥99% by HPLC)
HPLC profiling confirming ≥99% purity.
Sterility Screening
DNA-based microarray screening across multiple vials per lot to confirm no microbial growth.
Endotoxin Assessment (USP <85>)
Kinetic chromogenic LAL screening for bacterial endotoxin, reported in EU/mg on the COA.
Heavy Metal Analysis (ICP-MS)
ICP-MS screening for trace metals (arsenic, cadmium, lead, mercury, chromium) per ICH Q3D guidelines.
Conformity Verification
Confirms consistent purity and content across 3 or more vials per lot.
Fill Weight Confirmation
Net content verification to confirm lot consistency.
Fentanyl Screening
Screening to confirm the material is free of fentanyl.
Batch-specific Certificates of Analysis (COAs) are available, documenting full testing results across all verification protocols for research traceability.
