Research has associated GHK Cu with changes in collagen synthesis, antioxidant and inflammatory markers, and gene expression profiles in defined experimental systems
Future studies must better define the molecular context of antioxidant action, including the following: which biomolecules are being protected, the specific radical species targeted, the tissue and subcellular distribution of the antioxidant, and how levels of endogenous antioxidants and reactive oxygen species (ROS) change post-administration (e.g., within the mitochondria)
Pharmaceutical GLP-1 agonists offer many health benefits, however their high cost, potential side effects, and weight regain after discontinuation or the requirement for lifetime adherence are major deterrents for many individuals, and highlight the need for more accessible options with improved safety profiles
These molecules exhibit a range of biological activities, such as antioxidant, antiinflammatory, and ion-modulating effects, which collectively contribute to the inhibition of the apoptotic process
Whether that specificity translates to superior clinical outcomes remains to be proven through rigorous trials
