Oral glutathione is poorly absorbed because it is broken down during digestion
Research shows that even 30 minutes of sub-maximal activity is enough to increase oxidative stress and free radical formation, making boosting antioxidant defenses even more critical
It has a longer half life than IGF-1, which means that it stays active in the body for longer
Effects on gene expression Transcriptomic studies in cells exposed to GHK-Cu have reported broad changes in gene expression affecting genes involved in collagen and matrix synthesis, antioxidant defense (including superoxide dismutase, catalase, and others), DNA repair, immune signaling, and cellular metabolism
