Rx GHK-Cu

A critical broadsheet on the GHK-Cu copper-peptide literature — the copper tripeptide's mechanism set in plain type, with what the evidence establishes printed in black and what it still cannot promise stamped in the margin.

The full list of studies

GHK-Cu is a copper-bound peptide with a mixed research record.

This page gives every study used here, so you can check each claim at its source.

Each GHK-Cu number leads to a full source

Each numbered GHK-Cu claim leads to its full study below. Every entry gives the paper title, journal, and a free government link.

PubMed lists medical papers, while PMC often shows the full paper. Those links let you check a dose, percent, or measured change.

Main papers include Maquart 1988, Simeon 2000, Lane 1994, Pickart, and Mortazavi 2025. The list also covers wound materials and rat behavior.

One group produced much of the early work. The study pages point out that limit.

The full entries keep the lab names and filing numbers. The other pages leave those details here.
