A comprehensive review of GHK's biological actions in light of gene expression data. GHK upregulates genes involved in tissue repair (collagen, elastin, glycosaminoglycans) and downregulates genes associated with inflammation, cancer, and oxidative stress. Reviews evidence for GHK's effects on skin, lung, liver, stomach, and bone, plus potential anti-tumor and anti-aging roles.
