Help Anyone know any easy access chemicals to CTB?

[SomedayorNexttime]

I'm not super clear on the accessibility of SN, so I want to ask if there's any cheaper alternatives? Preferably chemicals? Maybe also tell me about where to purchase SN?

There are two main sources of SN at the moment. The first is SO in Germany, and the second is SD in China.

I've gone with the Chinese source even though it's taking a little longer to be despatched because I think there's less chance of getting a welfare check with that one.
