Dear CS-community, I don't know if the following website is known to any of you, but I just found it while searching to buy pre-made CS: http://www.silver-colloids.com/ I don't know how trustworthy all the information is at this website, I also did not yet check it out entirely, but look at: http://www.silver-colloids.com/Reports/reports.html You can even get a comparison chart, for what it's worth.
I found the website when I searched to buy "Sovereign Silver". But it costs 35 EUROS or DOLLARS for 120ml of 10ppm. Any remarks? PS: I know making CS yourself should be easy and cost less, but as I mentioned before to this list, I already have tried 2 different batches with silver from 2 different sources and I got 2 times a reaction that nobody really has an answer for... I tried one commercial product before and I did not have any bad reaction, but also not really a good result either. Maybe they sold me plain water ;=(. Anyway, I've became a little afraid of my selfmade batches... Kind regards, Filip
