Help SN testing results

[LongForWordlessSong]

Hey guys, I finally got around to testing my SN, I tested 2.5 G of SN in 500 ml water. I didn't have a syringe or anything to measure out 2ml so I didn't do the test with a second more diluted version but I did try it with just normal water as a control.

Spoiler: here's my SN and scale

Is it potent enough that I can follow an SN plan and succeed? Has it lost any potency at all? My SN is from 2021. Also, when using the same strips on water without my added SN the top 3 sections just come out completely white.
Thanks for the help guys. I really hope this is good and I don't have to worry about sourcing and I can just go now peacefully.

Not an expert, but it looks good to me. Perhaps when dosing do a little bit more if you doubt it.
