Hello there, tonight I am testing my SN. It arrived yesterday, as well as a scale and the test stripes. Today I bought distilled water and pipettes, so I have everything I need:

1 1)

Now I am following this guide:

Before I even opened the SN container, I tested my tap water and the distilled water with the test stripes.
Using two cups, each of them with 500ml distilled water.
Dissolving 2,5g SN in the first cup, stiring and shaking, waiting a moment.
Taking 1ml of the first cup, and adding it to the second cup, stiring and shaking, waiting a moment.
CUP 1: 1,25g / L
CUP 2: 10mg / L
Now I used multiple test stripes on both cups, as you can see. The test stripes for CUP 1 also changed color in like 2 minutes, from a very strong red to light orange. The color on CUP 2 also came fast, but stayed the same.

2 2) 3 3) 4 4)

Picture 3: Test stripe in CUP 1, the second I put it in.
Picture 4: You can see how the color on test stripes for CUP 1 (on the right side, sorry) changes over time.
Picture 5: Results. I used a lot of stripes for each test, they all turned out nearly the same. Picture is taken about 30 minutes after I tested, colors definitly not changing anymore.

I dont know anything about that stuff, but the orange is probably some kind of overreaction? Because the test stripe is not made for such an amount of Nitrit, would be my simple guess.
The result looks good to me, found my SN I think, but please let me know what you think. I will give an update for the blood testing, probably tomorrow.

Hmm, I noticed that the test stripes for ONLY tap water and ONLY distilled water turn out very pink as well, but much much slower.
They start to get color after 20-30 minutes and then keep getting brighter, till they almost reach the same level as the test stripes for CUP 2, after like 4 or 5 hours.
I tested more (only tap & only distilled water), same results.
7 8 10

Should I be concerned? I mean, following the instructions of my test stripes, I have to read the results after 60 seconds.
At that time the test stripes for only water have 0 color, while the one for CUP 2, which is most important, easily reached the right color, or even more.
So I think everything should be fine, still wanted to share that.

These results look Ok.
These test strips designed for home aquarium use aren't especially scientific, or accurate.
Interesting that pure distilled water records results. Maybe the water isn't so distilled after all, or maybe your test samples got cross-contaminated, eg by using the same pipettes, or picked up moisture from the work surface? Or maybe it just highlights how imperfect the test strips can be. Idk.
I would go by the manufacturers instructions. If they say read after 60s then do that. A google search showed one manufs instructions says "Any colour forming after the two minutes should be ignored.". I think they all keep reacting (changing colour) the longer you leave them. If the strong SN cup 1 initially turned strong pink/red, then later went orange is likely due to the nitrites being off the scale for the strip. It likely just got sick from the massive dose of nitrite you gave it, which is good. The in-range 10mg/L cup2 records correctly it seems, correct colour shade, as you state.
Tap water where I am is full of all sorts of nasties; chlorine, nitrates and VOC's and more, is very hard (calcium and other minerals) etc., and has to be treated with dechlorinator and water softeners and tested for pH before using in the aquarium.
As well as test strips there are liquid based tests for aquarium water use that you mix in test tubes, that are supposedly more accurate than these test strips, but personally I wouldn't bother, it's the same basic chemical reactions going on.
There is a more accurate blood test that can be done as well for SN, details should be findable via this site somewhere.
From your pics it looks like the common 'bm' brand of SN? I have the same. I have not done either the blood test or these test strips on it, but it seems legit to me; it looks the part and is packaged properly (correct labels etc) and tastes salty (I only dabbed a very small amount). I have no reason to think it's not the real thing.
Sorry this isn't more scientific. Just my layman's take on your results.

Thanks! I bought "Quantofix" test stripes, I think they are equivalent to the ones that Vizzy´s guide mentions.

Yes, probably something like that.

The only blood test I saw was just mixing a small amount with blood, if it gets brown: good. Or what do you mean?

Yes, to me it looks very legit too. Will do the blood test to be as sure as I can but I dont think its necessary. Im struggling to get Benzo´s, so I have the time to do it in detail.
and tastes salty (I only dabbed a very small amount)
Damn, be carefull with that! :-)

I only came across the blood test guide (or links to it) here alongside the test strip info, both for testing SN purity for CTB.
Can't remember where, sorry. But yes 100% sure it's the test you describe. I think it's more accurate and so preferred as a more scientific test of the purity of SN as blood will react (as you describe) only if the SN concentration is high enough to cause that reaction. The aquarium test strips react off their scale at miniscule purities by comparison, as you have demonstrated. From memory there's a few steps you have to go thru in the blood test I think, but it seems pretty simple to do. There are more detailed posts on this on here by people who know about it than me. Sounds like you do too.
Re test tasting; yes, there are warnings about test ingesting SN (basically don't!) which would seem a pretty crazy thing to do :smiling: . A few grams will kill. I only tasted a very small finger dab then rinsed out straight away. It's salty...
Let us know if you do any investigations into OTC AE's. Is something I am looing into without much luck atm. DM is fine if you prefer to chat privately.
edit: I think the test strips are made to be extremely sensitive as they have to react to chemicals in the low ppm's, so I wouldn't be bothered about distilled water registering something low on them.

Alright, I just did the blood test:
13 14 15
Not much to say I think. Blood turned brown in the second it touched the SN.

I found Metoclopramide online, without prescription, legally it seems. I live in germany and was a bit surprised that I can do that. If that helps, I can send you the link.
The site also sells Zopiclon, which is maybe an alternative for Benzo´s? Have to read into it.
(Only thing that is holding me back from buying Benzo´s in the DW is that im struggling with handling this stupid crypto bullshit ^^')
Are you only able to get that SN in Europe?
Dont know much about that! But it looks like in Europe it´s comparatively easy to get.

This is quite a process.

Question...I don't understand exactly the situation with the cups. Are cup 1 and cup 2 bottles with lids? I saw that you were shaking them, so it seemed like you would need a lid? Or are they more of an open cup?

what was your work surface and how did you protect it? Did you wear gloves?

Have a look at picture 1), on the right side you see the "cups" I used. I just took 2 containers from my kitchen that can measure 500ml. One is a glass bottle with a lid, the other one is just a simple open plastic cup. I used the glass bottle for CUP 1 because I can close and mix it easier, to dissolve the SN. To mix the solution in CUP 2 I just stired it for a while. I heard that you should avoid metal when handling SN, so I used a plastic pipette instead of the spoon.
So your containers should: be out of plastic or glass, hold 500ml, be somehow closable.
what was your work surface and how did you protect it? Did you wear gloves?
I didnt use gloves (but go for it, its better, be careful with that stuff). It is a linoleum table. And I used some plastic film as you can see.
