Buying GHK-Cu — Frequently Asked Questions

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

≥99% by reverse-phase HPLC, with LC-MS/MS confirming 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. Each CoA is batch-specific and lists HPLC purity, LC-MS/MS mass confirmation at 403.9 Da, endotoxin result, testing laboratory and test date.

What testing does GHK-Cu undergo before shipping?

Reverse-phase HPLC for purity by area under curve, LC-MS/MS for molecular identity confirmation, LAL endotoxin testing, and visual QC for appearance and particulate matter. All testing is performed by an independent third-party laboratory and reported on a batch-specific Certificate of Analysis.

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.
