GHK-Cu (molecular weight: 401.91 g/mol) is a naturally occurring copper-binding tripeptide studied for its role in skin biology, extracellular matrix remodeling, and wound repair models
For peptides that work systemically like growth hormone secretagogues that act on the pituitary, or repair peptides like BPC-157 that work through systemic circulation this is the only delivery method that reliably produces the expected effect
NRF2 provides a protective effect in melanocytes in response to both UV irradiation and oxidative stress 30,31 , through transcriptional upregulation of the antioxidant response element (ARE) genes including Superoxide dismutase-1 (SOD-1), Glutathione peroxidase-1 (GP-1), Glutathione reductase-1 (GR-1), Catalase and Heme oxygenase-1 (HO-1) 38,39,40
Small deviations in the baseline ratio between different batches can alter your concentration math during reconstitution
