N storage

[healthrecovery]

This question probably got asked many times but how long can you store N ?

I have heard that the expiration date on an unopened bottle is 2 years. If you store an unopened bottle in a cool dark place, it will be good for 20 years.

Can anyone confirm if this is really true that N will really last for 20 years, if you don't open the bottle?

How do you know if your N has gone bad?

How long will N last once you open the bottle?

Yes, PN says it can last up to 20 years if unopened and stored in a cool dark place.

People throw around the 30 day number on how long N will last after you open the bottle. But no one really knows the exact time for sure. It's probably longer than 30 days though

Not sure about knowing if the N has gone bad. Particles or cloudy maybe?

The powdered kind will last for many years if you keep it dry.

I heard that if it's clear and no crystals forming then it's good for years.
Not an expert though - just something I read.
