Developing functional musculoskeletal tissues through hypoxia and lysyl oxidase induced collagen cross linking PNAS Glycation of type I collagen selectively targets the same helical domain lysine sites as lysyl oxidasemediated cross linking Journal of Biological Chemistry GHK Cu Peptidos Everyone's calling GHK Cu a miracle peptide But let's separate marketing from mechanism. GHK Cu isn't magic. It's a signal. A signal that: Supports tissue repair Modulates inflammation Enhances collagen + Targeting lysyl oxidase like 2 (LOXL2) inhibits collagen cross linking and accelerates reversal of pre established liver fibrosis
