I am sorry to say that I have been advised on good sources before but did not keep good record. If anyone knows where to purchase sodium chlorite in bulk please put it here on this thread.

I have these sources but I think they are a little spendy.
Here are places to purchase bulk MMS in flakes. They don't look like very good deals. I will keep looking.
Here are a couple of sites that sell Sodium Chlorite:

https://sciencelab.com/page/S/PVAR/SLS4636
100 grams for $62.23
500 grams for $175.47


and I just found this page at curezone that has some interesting info:

I purchased mine very inexpensively: here is the website: https://sodium-chlorite-supplier.com/

I paid $12/pound (454 grams) for it. The quality was good. It is so much cheaper to make MMS1 and MMS2 yourself.
