A 2015 study used 150mg of a similarly administered form of glutathione, which is a good 33% higher than the Quicksilver dosage.22 But there's a silver lining in that Quicksilver is easy to titrate up as needed, and just an additional pump will get you up to that 150mg threshold (though at the expense of shrinking its use life)
