A study examining GHK's effects on human breast cancer MCF7 and prostate cancer PC3 cell lines found gene expression changes consistent with reduced proliferative and invasive capacity
What a COA should show: For a raw GHK-Cu ingredient, a legitimate Certificate of Analysis should include HPLC purity (look for greater than 98 percent), mass spectrometry confirmation of the molecular weight (340.38 Da for the free tripeptide), copper content by ICP-MS, and heavy metal panel
The procedure is quick and typically takes less than 20 minutes
Position your head the same way, use the same lighting, and photograph from the same angles each time
This single modification changes the stability profile, the absorption characteristics, and the practical utility of the peptide in ways that matter enormously for researchers designing effective dosing protocols
That such engineering was considered necessary is itself a comment on native DSIP
