However, it is not FDA-approved for medical treatment or injection, and regulatory status may vary by use
In some research contexts, observations have included mild and transient tolerability-related effects such as: Headaches Nausea Stimulation-related observations Temporary injection-site irritation or localized skin-response variability Research conditions, concentration ranges, dosage ranges, hydration status, administration frequency, and protocol structure may influence tolerability observations across experimental settings
In the present study, the cecal microbiome differed significantly across treatment groups, despite tightly controlling for several variables known to alter the microbiome in rodents
More importantly, they showed reduced markers of apoptosis
