another 3 m extension ??, page-6

After I had a look on the 3m web site I was of the opinion that the initial testing was in-vitro tests and the extention was to test in-vivo as this seems to be the way 3m goes about doing things.
Because there is no information about what was tested and what is to be tested and how these products are being tested we can not know for sure.
But I have spent a lot of time researching how 3m go about testing and doing business with there parteners and I think this last round of tests wer in-vivo.
It makes sence just think about it, why after all these years would they still be doing in-vitro tests and you would think they are way past that now.
This is only my opinion from the research I have done
