Research reference material
GHK-Cu
Assay pending. Not currently listed.
What it is
GHK-Cu is the copper complex of the tripeptide Gly-His-Lys. It sits alongside AHK-Cu as a copper peptide, and it is the largest component of our GLOW BLEND, where the laboratory reported 56.76 mg of it — 50.02 mg GHK plus 6.74 mg copper — in a 70 mg fill.
We intend to list it as a single-compound vial. It is not on sale yet, because a standalone fill needs its own certificate first, and the fill weight follows the report rather than preceding it.
The certificate
None yet, which is why this is not on sale. When the assay for a standalone fill is in, it goes up on the certificates page in full and the listing opens at the same time — not before.
Storage and handling
Supplied lyophilised and sealed. Hold the unopened vial at −20 °C, away from light and moisture; brief transit at ambient temperature does not affect lyophilised material. Once reconstituted, keep it refrigerated, avoid repeated freeze–thaw cycles, and treat it as you would any other short-dated laboratory reagent.
Bacteriostatic water for reconstitution is listed separately as a laboratory consumable. Work from the figures on the certificate and your own standard practice when preparing solutions — we publish the assay, not a protocol.
