GHK-Cus gene expression effects modulating an estimated 4,000+ genes in published research by Pickart and Margolina operate at the cellular level throughout distributed tissues when administered systemically
Research interest nonetheless expanded considerably through the 1980s and 1990s, as investigators began exploring DSIP's broader neuroendocrine roles, including its interactions with the HPA axis, circadian timing systems, and stress-response pathways, establishing the compound as a multifunctional regulatory neuropeptide whose biological significance extends well beyond its original sleep-focused characterization
GHK-Cu is also shown to stimulate collagen and elastin, smoothing and firming the skin over time without the potential skin irritation of prescription tretinoin or over-the-counter retinol
