The research case for GHK-Cu is built on several pillars: demonstrated collagen stimulation (up to 70% in laboratory models), wound healing acceleration across multiple tissue types, gene expression modulation affecting approximately 4,000 human genes, anti-inflammatory activity, and antioxidant defense support
Intracellular glutathione, which does the actual antioxidant work, remains more stable for 4872 hours before declining measurably
The risk with unregulated online sources isnt primarily theoretical
Among the peptides in this article, it has some of the more credible evidence, particularly for skin health
