KLOW Peptide Mechanisms GHK-Cu: collagen and structure GHK-Cu is a copper-binding tripeptide mapped across more than 4,000 genes: collagen synthesis, antioxidant defense, and wound-healing programs trend up, while inflammation and tissue-breakdown programs trend down. Circulating levels fall with age, from roughly 200 ng/mL at 20 to about 80 ng/mL by 60. It clears damaged matrix while helping new collagen form and cross-link into stronger structure (matrix remodeling and lysyl oxidase activation). See the in-depth GHK-Cu guide
