There is a slight discoloration if you look closely, but no raised scarring, no texture issues
The method can assay GSH in whole blood, plasma, serum, lung lavage fluid, cerebrospinal fluid, urine, tissues and cell extracts and can be extended for drug discovery/pharmacology and toxicology protocols to study the effects of drugs and toxic compounds on glutathione metabolism
Notably, the compound is stable across a wide pH range and fully soluble in aqueous media, unusual properties for a peptide of this size that are attributed to its high proportion of proline and charged residues
SAG is a prodrug of GSH: the acetyl group renders the molecule stable and absorbable in transit, but it does not itself perform the antioxidant functions of free GSH
Results may vary and consistent use over time is necessary for potential benefits
