- Pal-GHK and GHK-Cu are sometimes discussed as equivalents in cosmetics marketing, but they are chemically and biologically distinct compounds for research purposes. GHK-Cu's copper component is not cosmetic — it is mechanistically important for LOX activation, antioxidant enzyme induction, and likely for some of the gene regulatory effects attributed to copper-dependent transcription factors.
- Researchers who encounter Pal-GHK in the literature should not assume its findings transfer to GHK-Cu experiments, and vice versa.
