Help Does anyone know how to test sn?

[endofdays]

I have ordered sn from Ic, but want to confirm that it is sn and the purity. I know many people have ordered from him but has anyone actually found a way to test? I know you can use a simple blood test to see the effect it has but this does not indicate it is sn simply that it contains a reducing agent. I know you can buy aquarium test strips but again they do not confirm that it is actually sn. I have searched the web but cannot find a suitable test, does anyone know how to proceed?
I am desperate to ctb but don't want to make my situation worse by taking something which is not as described.

Either the blood test or aquarium test. The blood test you take some blood of yours onto a white plate or cup so the color changes is noticeable and then mix a bit of SN with the blood and wait till it turns into a brown color. But if you do use the blood test just be careful handling the SN okay in case. Read this thread: https://sanctioned-suicide.net/threads/reminder-be-careful-when-handling-sn.84899/
As for the aquarium test I don't know much about but here's some sources I found:
