Frozen Urine, what happens after 1 year?

[14MaryJane]

I've searched the threads, and all I could find was that urine will develop an ammonia smell when its past a useful stage.

I'm, right at 11mos after freezing my own supply, there is no ammonia smell, yet.

Is the smell the only key to determine if its still good? Is there anything else I should worry about?

Thanks to anyone in the know who can answer this.

Also, the drug testing authorization says they test for illegal drugs, dilution and substitution. Any idea how they can test for subbing? It is a pre-employment so I'm not worried about someone holding my hand.


Thanks,
MJ
