So theres something to this
It is the opposite an official statement that nobody knows what it does, mirroring the FDA's own position
Can I use GHK-Cu with vitamin C
Research has examined its role in: Stimulating collagen and elastin synthesis in fibroblast cultures Modulating matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) Promoting angiogenesis and endothelial cell recruitment Regulating gene expression across thousands of human genes Supporting tissue remodelling in wound, lung, bone, and gastrointestinal models Investigating anti-inflammatory and antioxidant pathways GHK-Cu and Collagen Synthesis Research Research published in FEBS Letters confirmed that GHK-Cu stimulates collagen synthesis in fibroblast cultures, with stimulation beginning between 10 and 10 M, reaching maximum effect at 10 M, independently of any change in cell number
This interaction reduces inhibitory binding between caveolin-1 and endothelial nitric oxide synthase, allowing increased enzyme activity and nitric oxide production in endothelial cells
