Your supplier of CDS is almost correct when he says that 1 ml of 3000 ppm CDS is
equal
to a 3 drop dose of MMS1, but that would be for external use, not internal. For ingestion of 3000 ppm CDS, you would need to take 6.7 ml of CDS to equal a 3 drop dose of MMS1 in a normal stomach. The reason is because MMS1, when "activated" for 30 seconds externally (before ingestion), is only about 10% activated - the other 90% activation should happen in a stomach with normal amounts of acid. Most people have normal amounts of stomach acid to activate MMS.
Since you have throat irritation when taking MMS1, you would likely have even more irritation if you used CDS, because CDS is fully activated externally - it does not need stomach acid to activate.
If you decide to try Scott's un-activated MMS method, I would follow Protocol 1000 using the same number of MMS drops. The difference between the two methods is that all activation takes place in your stomach with the un-activated MMS method. And, you can make up a daily bottle of water plus the number of drops you plan on taking. Mark the bottle into 8 equal parts and ingest 1/8 of the solution hourly. If necessary, you could add additional water to each hourly dose. I am using that method once a day for maintenance dosing and the bottle is small, so each dose is only 2 fluid ounces (60 ml) and I don't have any problems. If you plan on taking 8 drops of MMS daily, then add 8 drops to a glass bottle filled with water and ingest 1/8 of that total, hourly.
