i can scratch half of thos off the list just off the top of my head. for example, medex, which is where i got my first bottle, does not carry lugols. period.
pigeon supply stores do not carry full strength lugols. it is not lugols, no matter what they call it.
go by what we know to be available, hassle free, and proper quality and jcrows and breastcancerchoices is it for Lugols and iodoral respectively. i cant wait to hear testimony of personal experience to the contrary.
