In our opinion, the COPD study (Campbell et al.) is the most representative in this aspect, because not only were the gene signatures derived from areas with histologically confirmed pathology, but also GHKs effects on affected lung tissue were tested in vitro and their correlation to gene effects was well-established [37]
Early studies show improvements in brain glucose metabolism, reduced inflammation, and protection of neurons from degeneration
GHK-Cu stimulates chondrocyte activity and glycosaminoglycan synthesis
Suddenly, RDA is not enough
Patience and consistency are essential, as glutathione works gradually through cellular mechanisms rather than providing immediate cosmetic changes
