However, most research is from animal studies

2 GPX family and oxidative stress 2.1 GPX1 Glutathione peroxidase 1 (GPX1) was first identified in 1957 as a red blood cell enzyme that protects hemoglobin from oxidative stress (MILLS, 1957)

Quality matters more than any other factor when it comes to peptide effectiveness

Moreover, microbial production of hydrogen sulfide by sulfur-reducing bacteria has been linked to enhanced host GSH production, suggesting that microbial antioxidative agents can regulate the host GPX4/GSH system, thereby further contributing to the protective effects [37, 38]

Early in a cycle, many report changes in rest and recovery, which can be an encouraging signal
