Did blood test etc... And yes, it does cure us. Heh!
The feeling of actually seeing it relieved me. I plan to CTB in about 3 months, or whenever I need loose ends tied up
I think this is a problem!
I'm guessing that in order to test your sn you had to open the packet? Correct?
If you opened the packet then air/oxygen would have entered the packet.
Once sn is exposed to oxygen, (I have read) it slowly changes from nitrite to nitrate, which is a bad thing to have happen.
So, I think, that by the time you wait 3 months you'll have a useless packet of sodium nitrate (&/or a hard block of something, no longer powder, like another member reported recently).
Of course I'm not a scientist so don't take my word for it but please do look it up & check it.
