I have asked several questions regarding subbing and frozen urine. So, thanks in advance for the help.

Here's the deal, I have subbed 4 times using frozen samples from 2 different friends and passed all 4.

Today I used the last 2ozs for my PO but this is urine that has been frozen and thawed 2 times. It was only unfrozen at room temp for a total of 2 hours, however it smelled stronger than the last 2 uses. There were no visable differences, but could that odor be detected and identified as "old"?

If anyone has a logical answer, it is truly appreciated.
