Help Which SN should I use?

[lilin]

So I've ordered sn from two different companies. One of them was produced in 2021 and has expiration date 01.01.2024. this one is 99% pure. I'm worried it might have reacted with oxygen a little since it was produced. Obviously it's in a closed container but who knows if it's totally air-proof...
The second one was produced in december this year. Expiration date is 2026. BUT the purity is only 96%. Is it enough?

The instructions of the peaceful CTB indicate that the purity must be greater than 95%. But this is what I read. I can't promise or guarantee anything.

Sounds like either one is good to me. You can test it with some blood, not for purity, but just to get an indication if either are what they say they are. I've read SN, if properly stored, can last much longer than expiration dates. I doubt there are any issue with either one.
