Is SN supposed to have a use by / sell by date on it?

Mine doesn't. Surely it should if it's used in meat production?

Do the aquarium stripe test to check if it's at least 98% pure SN. Then it should be ok.

I think it will eventually go off past the point where it's suitable for ctb, but that won't happen for years unless it's liquid

I don't have one so I have to use the blood test. Also I've checked the website again and it says it's pharma grade not food grade and shouldn't be used in meat production so I guess that's ok?

Pharma grade means that it's 100% pure. I think it should be ok, but I'm not sure if the shelf-life isn't shorter than in case of food grade. It's strange that there is no date of expiration on the package..

Mine is also lab grade and has no shelf life date on it. I got it at the beginning of 2020. What do you think about mine?
