While animal studies suggest safety, long-term human studies are lacking
GHK-Cu stimulates fibroblasts and the synthesis of collagen, elastin, glycosaminoglycans, and other matrix components, and it supports the copper-dependent enzymes that crosslink connective tissue
30 l of the lysis buffer (1 mM TrisHCL, pH 7.4, 1 mM EDTA, and 0.5% Triton X-100) was added to each well using a multichannel pipette and mixed gently, with 5 l from each well mixed with 195 l of 1:5 Bradford reagent (Bio-Rad) for protein quantification
However, results can vary depending on the individual, dosage, and overall health
