Help Is laboratory grade SN going to do the trick?

[ghqkiiia2]

I can't find food grade sources, but since I work in a academic institution, so I successfully obtain 3 bottles SN from different suppliers. But they each contained different small part of other chemical compound, were they the same as food grade?
I am new here and not fully understand the regulation on products' picture, maybe I will post some pictures when I understand the rule better.
Thanks.

The price is extremely low, I acquired these tree bottles for 5-7 us dollars each. they all contained 500 gram of SN, that is not the price I read on Most SS posts, So I feel kind of fuzzy in this meaning.

Depending on the country it can be very cheap, if it has all the technical information etc from a good supplier it should be good.

You can always do a blood test or aquarium test to see if it works.
