Topical products should not be treated as equivalent to injectable preparations
Glutathione Levels Increased Across All Blood Samples Liposomal Glutathione raised glutathione levels in all parts of the blood tested: Whole Blood: 40% after 2 weeks Erythrocyte (red blood cells): 28% after 1 and 2 weeks Plasma (liquid part of blood that carries nutrients, hormones, and waste but no cells): 25% after 2 weeks PBMC (white blood cells): 100% after 2 weeks Increases occurred in all compartments suggesting a systemic effect and that other less-accessible tissues may be impacted in a similar manner. Participants starting with lower glutathione (GSH) levels saw the biggest improvements after taking the supplement
Medications know to cause bone marrow suppression (e.g., myelosuppressive antineoplastic agents) may result in a blunted or impeded response to methylcobalamin, vitamin B12 therapy

This is a non-physiological state, but its incredibly useful for studies looking at the effects of chronic GH elevation rather than pulsatile signaling
