A microarray or sequencing run quantifies how much messenger RNA for each gene is present in a sample at one moment. That is a real measurement of a real quantity, and it is sensitive enough to pick up thousands of genes at once, which is why it became the standard screen.
It is a screen, though. Its output is a list of candidates ranked by apparent change, with the statistical caveats that come from testing tens of thousands of hypotheses simultaneously.
Between transcript and functioning protein sit translational control, protein half-life, folding, trafficking and modification. A transcript can rise with no change in protein if the protein is being degraded as fast as it is made; a protein can rise with no change in transcript if its degradation slows.
Measured correlation between transcript and protein levels across a cell is moderate, not tight. That is a well-documented property of cells rather than a flaw in anyone's experiment.
The large gene-count figures that circulate about GHK-Cu come from expression screens. Quoting them as though a corresponding number of proteins had been shown to change overstates them, and quoting them without the model, concentration and time point overstates them further.
The disciplined version names the method: an expression screen in a particular cell type reported changes in this many transcripts at this threshold. That sentence is both accurate and still interesting.
Targeted follow-up on the candidates that matter: quantitative PCR for the transcript, then western blot, ELISA or mass spectrometry for the protein, and ideally a functional assay downstream of it. The matrix literature contains protein-level and functional measurements as well as expression ones, and those are the stronger citations.
