I skimmed at least this a couple days ago; then read this one more
thoroughly tonight.

I am not familiar with ASAP. I used Futurebiotics (stated as 5ppm) for the
first 2-4 weeks and then switched to homemade.

I am not familiar with the above methods for making colloidal silver. It
sounds like a "reduced" silver nitrate was used, yet it was called colloidal
silver. This method is completely foreign to me. I would be very surprised
if anyone who makes their own CS uses a method like this.

My CS was clear and pale yellow or colorless depending on the batch and the
method (low vac dc 30 volts or high vac). I don't have any idea if what they
are calling colloidal silver is actually colloidal silver. I don't
understand why they made it in a way so different to how the commercial and
homemade CS are made. My very first tested batch was 3 ppm; a subsequent
batch was 7 ppm as I recall. I increased process time to approximate 10 ppm
with the dc low vac unit. I followed manufacturer's directions to
approximate 15-30 ppm solution using my commercial hi vac AC unit.

It is quite apparent that at least two of the three specimens they tested
were not made in the manner most commonly implemented by most individuals I
know of who make CS. So I can not assume that the results apply to my CS,
especially since mine did help me get well.
So this study, though interesting, does not shed any more light on just how
my kind of CS works. They only speculate that it could be "impurities,"
silver ions and/or oxidants. I wonder if they will go on and research these
speculations...
