Research-Grade Compound

GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring copper-binding tripeptide found in human blood plasma, saliva and urine. Molecular formula C14H24CuN6O4, molecular weight 403.9 Da as the copper complex — 340.4 Da for the free tripeptide without copper. CAS 89030-95-5.

Purity standard: GHK-Cu is sourced to ≥99% by HPLC — sourcing spec. That is the specification every batch must meet, not a measurement of any one vial — the measured figure for a batch is on that batch's Certificate of Analysis.

Buying GHK-Cu — Frequently Asked Questions

What purity standard does Peptide.Express use for GHK-Cu?

Sourced to a ≥99% HPLC specification. Where a certificate reports a mass, compare it with the 403.9 Da copper-complex mass. The mass confirmation matters more than usual here — it distinguishes the copper complex from the uncomplexed 340.4 Da free tripeptide, which some suppliers sell under the same name.

Where is the Certificate of Analysis for GHK-Cu?

On this page and in the Peptide.Express lab results library. Sourced against a ≥99% HPLC purity specification. Third-party Certificates of Analysis are published where on file.

What testing does GHK-Cu undergo before shipping?

Where a certificate is on file, it shows the assays that laboratory reported. Those can include reverse-phase HPLC, LC-MS/MS, an endotoxin result, and visual QC. A missing line is not a pass and is not proof the assay never ran.

How should GHK-Cu be stored before and after reconstitution?

Lyophilized at -20°C, desiccated and protected from light, stable for 24 months. Reconstituted at 2–8°C for 14–28 days. Light protection matters more for GHK-Cu than for most peptides because the copper complex is photosensitive — store the reconstituted vial in an opaque container or wrapped.
