GHK-Cu 50mg

GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a naturally occurring compound first isolated from human plasma. It is supplied here as a lyophilised powder in a 50mg vial. Its blue colour comes from the bound copper.

FAQs

What purity is this batch?
The current batch of GHK-Cu tested at 99.2% by HPLC, with identity confirmed by mass spectrometry. The full certificate of analysis, number 026-G81-TSX, is shown below and can be downloaded.

Why is the powder blue?
The colour comes from the copper(II) ion bound to the peptide. A blue powder is expected; the certificate shows a copper content of 15.2%.

How should it be stored?
Keep the sealed vial at 2–8°C for short-term storage or at −20°C for long-term storage, away from light and moisture. Let a cold vial reach room temperature before opening it.

Is this the same as GHK Cu?
Yes. GHK-Cu is also written or searched for as GHK Cu, GHKCu, GHK copper, copper peptide or copper tripeptide-1. All of these names refer to this copper tripeptide.
