ghk-cu declines with age By 30, your skin produces about 25% less collagen. By 40, that number can reach 40%. This decline affects more than just how your skin looks. It changes how it heals GHK-Cu Peptide | The benefits,

Once reconstituted with bacteriostatic water, refrigerate at 28C and use within 28 days longer storage risks oxidative degradation of methionine residues critical to receptor binding

S7)):115122

The bound peptide delivers copper to lysyl oxidase active sites at the collagen crosslinking interface and modulates gene expression in adjacent fibroblasts by altering TGF- and Smad signaling pathways

It does this by taking a methyl group from 5-methyltetrahydrofolate (the active form of folate), transferring it back to the cobalamin, and releasing free tetrahydrofolate

This function theoretically contributes to weight loss
