Has anyone ever attempted with old SN?

[Meditation guide]

My SN is 3 years old. I just wondered if anyone has attempted with SN that old and failed? I'm not sure I can cut myself to get some blood to test it. I've never opened the jar of it. I can see through the bottom of the jar and it's still a sand texture not all clumped up like moisture got to it.

Supposedly if it's never exposed to fresh air SN decays super slow and has a lifespan longer than any of our lifespans. A little air in the jar is okay as long as all the SN hasn't crystalized

As long as the SN hasn't been exposed to any air then its safe to use. Also, you have to store it correctly so if you did that as well then you can still use it.

I will but I won't be able to tell you if I was successful

Wait, what do you mean by crystallized?

I also have SN 3+ years old, although haven't opened to test it.. I've kept it in a storage box in my room where sometimes temperatures have risen quite high due to heatwaves. I plan on testing it soon.

Also have TIG SN but apparently it's no good/not pure enough.
