What the research shows
Researchers implanted small mesh chambers beneath the skin of rats and compared GHK-Cu with saline. Chambers exposed to the complex accumulated more collagen and other tissue-matrix components. The investigators could recover the chamber and analyze its contents directly. The chamber directly exposed healing tissue to the complex. Studies of a topical product also need to account for the intact skin barrier. GHK-Cu in an experimental rat wound chamber.
Documented formats
The study used GHK-Cu in solution within a wound chamber. A finished topical formula introduces a different route and other ingredients that may influence delivery.
Testing and purity
Check how the laboratory confirmed both the GHK sequence and the copper-to-peptide ratio. Quantitative measurements can distinguish bound copper and residual free peptide more reliably than color.
How to read a batch reportQuestions about GHK-Cu
What does Cu mean on a report?
Cu is the chemical symbol for copper. Check whether the stated amount refers to copper alone, to the peptide, or to the combined complex.
Does more collagen in a wound chamber predict a cosmetic result?
The chamber measures tissue deposited during repair. A cosmetic claim requires measurements in people using the particular finished formulation.
