Terence, I would say you are not taking colloidal silver
but possibly silver protein, which is the only way to get 
over 30-40 PPM. DC produced Cs is difficult to make 
at over 20PPM due to crystallization and users inform
me HVAC can not produce over 40PPM.

Now, if you want to get technical, PPM is by weight so
it could be a few lumps of silver in a bottle but then it
would still be mis-labeled as that is not a colloid!

It could be a solution of silver salts (not colloid) as then
you could get many 100's of PPM. It could also be just
mislabelled and why the FDA keeps bothering us!

The problem I see with very strong (concentrated) 
medicines is the chance of mis-use or overdose!
Do you take 1/30 the dose others use? More is
not often better and a homeopath will say less is
better!

Treating your gut with an antibiotic should be for a 
short term, as you also kill off you natural flora. I
would not trust 150PPM and suggest you try a "more
normal" silver colloid and just take more  of it.

We test free, as do others, if you want to check the
TDS but only a lab test can tell you what is in it!

Terence said :Hello,

I am very new here, and I find this list
very interesting.

I have some questions I would like to ask
and know.

Is the amount 150ppm CS very strong?

I am using it to help me intestinal problem.
The taste of the CS is very very metalic.
Is there anything wrong with it?

Regards,
Terence.
