bds51, I'm a little confused. MMS2 is calcium hypochlorite. It's a different thing than MMS1 (which is sodium chlorite, and when activated becomes chlorine dioxide) - MMS2 is used in the protocol 2000 for life-threatening diseases.
We used to activate MMS1 with a 10% solution of citric acid (or lemon juice or vinegar) and when we activated it, we used 5 drops of activator and 1 drop of MMS1
Now, we use a 50% solution of citric acid, and it takes 1 drop of MMS1 and 1 drop of citric acid to activate - or a 1 to 1 ratio. (usually we use more than one drop in a dose. Note that when we talk about a 3 drop dose of MMS, we're talking about 3 drops of MMS1 and the correct number of drops of the activator - since that's a variable we don't know, we just say a 3 drop dose.
MMS2 does not require any activator and is usually delivered in a capsule.
