Glutathione vs SS-31

Glutathione and SS-31 are both stocked here and are often considered together. This page sets out what differs between them: their class, the sizes and price per milligram, the shape of the published evidence behind each, and where each stands under Canadian law. It does not rank them, because which is appropriate depends on what is being studied.
