For instance, in male rats that were administered supra-therapeutic doses, an increased GSH level was obtained in addition to elevated SOD and CAT activities

Neuroproteomic study of nitrated proteins in moderate traumatic brain injured rats treated with glutamyl cysteine ethyl ester administration post injury: insight into the role of glutathione elevation in nitrosative stress

The key is making each reduction intentionally, not accidentally drawing less because your vial is running low or your syringe hand was less precise that morning

Combining with other recovery or regenerative protocols (e.g., nutrition, rest, physical therapy) to maximize effect
