GHK-Cu References: the paper behind each claim

How the GHK-Cu paper list helps you check a claim

GHK-Cu is a short protein part joined to copper. This page lists each study used for a claim. The number beside a claim matches the number of its paper below.

One research team wrote many of the early papers. Other groups later tested face cream, wounds, hair roots, lungs, and scarring. When a paper is open to the public, its title has a link. You can choose that link when you want to read the study yourself.

Which GHK-Cu findings came from other research teams

Loren Pickart and his team wrote many GHK-Cu papers, starting with the 1973 report. When one team does much of the work, the findings are less sure. Later teams checked some of the same broad claims in their own studies.

Independent work in 1994 tested diabetic foot sores. Studies in 2002 and 2006 tested face cream and care after a CO2-laser. A 2007 dish study tested hair-root cells. Together, these skin and hair papers mostly pointed toward some benefit, though the hair proof stayed thin.

A 2012 study used damaged human lung cells, while a 2022 study used smoke-exposed mice. One 2024 paper tested lung scar cells. Another 2024 paper checked passage through skin, and a 2017 review covered wrinkle work. These studies add support, but they don't replace large human trials.
