tripeptide glutathione 21st Century 500mg Reduced – Antioxidant & Liver Support with Milk Thistle, Alpha Lipoic Acid, 120-Day Supply, Vegetarian Capsules, Non-GMO : Health & Household Chemical structure of glutathione (GSH),

When the FDA places a peptide in a restricted or high-risk category [known as Category 2], it is explicitly signaling that it has identified safety concerns and that enforcement discretion does not apply. But, as Hajduczok notes, just because something is not FDA-approved doesnt mean its illegal to compound, but the restricted peptides should not be compounded

By-products of this process are potentially harmful molecules known as reactive oxygen species (ROS)

It does not just act as a shield
