I am in the US.
I purchased 1 pound of sodium chlorite on ebay for $7 with $12 shipping for a total of $19.
In the future, I will look for a source who I think has a high quality of sodium chlorite.
I do believe what I received does work fine.
I mixed my own in my kitchen following the first book by Jim.
I initially used vinegar, then a lemon, then I went to a spice company and purchased 30 ounces of citric acid for I think was $6.71.
I had used 10%, then moved to 50% and for workdays/weekdays, I usually mix up 1/4 teaspoon and drink 1/8th of that every hour or so.
It has a strong chlorine dioxide smell as stated by Jim.
I purchased 99% DMSO from Jacob Labs and took some of that to mix 70% DMSO with 30% distilled water.
Neither my 99% DMSO or my 70% DMSO has any smell.
I just mixed 4 drops MMS with 4 drops 50% citric acid. There were no bubbles.
I waited about 22 seconds. There were no bubbles.
The color was a deep yellow.
I added 4 drops of 70% DMSO and waited 3 minutes. There were no bubbles.
After 3 minutes, there were still no bubbles and the color was still yellow.
I added filtered city water, maybe 3 ounces of water. I held my nose and drank it.
I added more water to the glass again and drank that.
This was the first time I held my nose and it worked to keep me from the bad taste.
I will try and remember to hold my nose next time.
I have had great results with MMS. This batch helped me to get rid of my acid reflux a year ago and I no longer need to get Nexium (20mg).
My other results were an almost immediate relief of knee pain, immediate relief of toothache when using it on a toothbrush.
My mom had a bump on her forehead for years and used MMS on it and it fell off right away with no mark on her skin.
I probably have other good results but can't remember right now.
I wish you well and I hope this helps.
