in the refining of silver bullion, there are  apparently two grades of silver 
bullion,  .999 fine, and .9999 fine. according to bob beck, rest his soul, 
suggested that .999 silver was of adequate quality to make CS pure enough for 
internal use.

i don't know who these people are that are quoting 99.999% pharmaceutical grade 
silver. are they using .999 fine, or .9999 fine, or do they have something new 
at .99999 fine. if so, i've never been able to find any reference to this 
degree of refining.

what grade of silver bullion are these people using, using the proper refiners 
grading?
