The injection is meant to amplify the slow-wave sleep growth hormone pulse, and even one drink close to bed measurably reduces slow-wave sleep depth
Additional caution or monitoring may be appropriate in research settings involving: Active cancer- or tumor-related research models, where antioxidant-related pathways may influence cellular-response or treatment-response mechanisms Severe asthma or hypersensitivity-prone research models, as rare sensitivity-related observations have been reported in some experimental contexts Sulfur-sensitive research models, due to Glutathione containing a thiol (sulfur-containing) group Complex hepatic-function or detoxification-related investigations, where antioxidant modulation may influence oxidative-stress or liver-related biomarkers Research conditions, research amounts, protocol duration, administration frequency, and concurrent compounds may influence tolerability observations across experimental settings
