GHK-Cu means GHK joined to copper. GHK is a short peptide. When you read a study, check whether it used GHK alone, GHK-Cu, copper alone, or a finished product.
1. Check what was tested
The amount of copper and how it is joined to the peptide can matter. JD BioWorks’ GHK-Copper research overview explains the different forms and studies.
2. Check how it was used
Some research concerns products applied to skin; other research concerns cells or animals. A result from a cream does not prove the same result for a separately sold dry vial.
3. Check what the lab report answers
Tests for identity, purity, and mg in a vial answer different questions. They do not establish every property of the copper mixture or how it behaves after mixing. See our COA guide.
4. If it is in a blend, check the blend
A study of GHK-Cu alone is not a study of GLOW or another mixture. Our blend guide explains what to check next.
