Trials dosage is about 1260 milligrams/day. The previous phase experiments determined that this dose, and not less, raised enzyme level enough to become effective is cleaning out toxic clumps. I started Ambroxol at 17/day x 75mg (1275mg) tablets this week. I feel good so far. Hopeful. Fingers crossed. Wish I was in UK so I could participate in the study so this would be free, but it's also good to know I'm not in the placebo group.
Currently in Europe and ordered it via online pharmacy.
