glutathione synthesis in liver Three amino acids walk into a bar….the adventures of supporting fatty disease using serine & nicotinamide riboside A Literature Review of Glutathione

found that blocking Gln metabolism can enhance tumor-specific immunity by inhibiting the transcription of CSF3 in tumor cells, which decreases the generation and attraction of MDSCs and stimulates the creation of pro-inflammatory TAMs (42)

Excess copper can promote ferritin depletion and disrupt iron metabolism, thereby sensitizing cardiomyocytes to ferroptosis, a process that synergistically aggravates I/R injury [67]

Using distal lung fibroblasts isolated from former smokers with and without COPD, we found that GHK (10 nM), like TGF1 (10 ng/ml), induced alterations in integin-1 localization (green staining in Figure 6a) and reorganized actin to form contractile filaments (red staining in Figure 6a)

It also attenuated lipopolysaccharide-induced acute lung injury in mice by inhibiting NF-B-mediated inflammatory responses 169

If you don't see results after 4 to 8 weeks, it could be due to low bioavailability (using standard pills instead of liposomal forms) or a high "toxic load" that is depleting your levels as fast as you can replenish them
