Why a GHK-Cu mass spectrum has a signature nothing else in the vial shares

Published 24 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Natural copper is about 69 per cent copper-63 and 31 per cent copper-65. A molecule containing one copper atom therefore appears in a mass spectrum as two peaks two mass units apart with roughly that intensity ratio. Copper-free GHK shows a single peak. The pattern confirms the metal is present and bound, independent of chromatography.

Where the pattern comes from

Isotopes are atoms of the same element with different numbers of neutrons. Most peptides are dominated by carbon-12 and hydrogen-1, producing a main peak with small satellites. Copper contributes two abundant isotopes, so a copper-containing species splits into two comparable peaks. The 69:31 ratio is the fingerprint.

It is one of the clearest isotope signatures among common metals.

What it confirms

That the species at the expected mass contains copper — not merely that something of about the right mass is present. It distinguishes GHK-Cu from copper-free GHK, which would appear about 61 mass units lower as a single peak. A certificate reporting the doublet has confirmed the complex.

A single peak at the GHK-Cu mass without the pattern would be an unexplained species.

Why it matters for a blend

In GLOW, GHK-Cu is the only copper-containing component, so the isotope pattern identifies it unambiguously among three species. Analysis of the blend leans on this.

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.
