What a purity figure for this compound is measured against

Published 24 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Pharmacopoeias publish official reference standards for established medicinal substances; GHK-Cu, a research compound, has none. Any purity figure for it is therefore relative to a manufacturer in-house reference, characterised by orthogonal methods. Two certificates from two sources reporting the same percentage are not directly comparable unless the methods and the references are stated.

What a reference standard does

It is a well-characterised sample against which methods are calibrated and batch results judged. With an official standard, any laboratory can calibrate to the same material. Without one, each producer characterises its own, and the quality of that characterisation is the foundation of every figure that follows.

This is standard practice and legitimate; it is also why the method must be stated.

How an in-house standard is made

A batch is characterised exhaustively — mass spectrometry, amino acid analysis, copper content, water, counterion, chiral purity — and its peptide content assigned from the sum. It then serves as the comparator for routine batches. Its documentation is the anchor of the certificate chain.

The copper complex adds copper content to the characterisation a plain peptide would need.

How to read a percentage

As a figure relative to a stated method and reference. Identity by mass against the calculated value is the least reference-dependent check and is the one to look at first.

GHK-Cu is supplied by REVIVE LAB UAE for laboratory research use only, with identity by mass spectrometry and purity by HPLC for the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
