GHK-Cu - 100 mg

Q: Is a certificate of analysis provided with GHK?

Yes — the current lot of GHK 50 mg has a third-party HPLC certificate of analysis from Janoshik, independently verifiable by lot (verify key EP4QIRBYZC47). The current lot assayed 99.846%. Yes — a third-party HPLC certificate of analysis for GHK 100 mg is published here from Janoshik, independently verifiable by lot (verify key FFU7FYYJNJ9V). The report assayed 99.959%. The report prints no batch ID, so it does not identify a lot. We publish the certificate before making any purity claim; this is a research chemical for laboratory use only.

Characterization

What it is, stated plainly.

What it is

The copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys). The copper ion is coordinated by the imidazole nitrogen of the histidine side chain together with the N-terminal amine and a backbone nitrogen, which is what distinguishes the complex from the free peptide. Published work sits in the extracellular-matrix and copper-transport literature.

How a lot is verified

Purity assayed by third-party HPLC and net content (mg per vial) measured by the lab, with a certificate of analysis published where a report exists.

Handling & storage

Supplied as a lyophilized powder. Store at −20°C, desiccated and protected from light. Handled per the receiving laboratory's procedures. Not for human consumption.
