What to Check When Your GHK-Cu Arrives
Not every irregularity on arrival is a defect, and not every compound is defective under the same conditions. Here is what actually matters when a GHK-Cu shipment arrives.
In plain English
The dry powder should be a distinct blue. A pale, faded, or unevenly coloured cake means the structure degraded before it reached you — an arrival check available for no other compound here, and well worth using.
What GHK-Cu actually is
GHK-Cu is three amino acids holding onto a copper atom — and the copper is part of the molecule, not an additive. It was identified in human blood in 1973, and researchers noticed its levels fall considerably with age. It is the only compound here whose condition you can partly judge by looking at it.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Arrival inspection for GHK-Cu
The dry material should be a distinct blue powder. A pale, faded, or inconsistently coloured cake indicates the complex has degraded before it reached you — an arrival check available for no other compound in this catalogue, and worth using.
Storage on arrival
Documentation to check
Peptide purity alone is insufficient for a coordination complex. The informative figure is copper content — ideally by ICP-MS or atomic absorption — confirming the intended peptide-to-copper stoichiometry. A COA reporting only HPLC purity describes the ligand while saying nothing about whether the metal is present in the right proportion.
What GHK-Cu is studied for
The best-populated area of the GHK-Cu literature, examined in dermal fibroblast models.
Studied for effects on the MMP/TIMP balance governing matrix turnover.
Copper itself is an angiogenic cofactor, and the complex is studied in that context.
Plasma GHK falls substantially between early and later adulthood, a finding central to research interest in the molecule.
