The wizinator company was very recently put out of business based on internet articles by the feds.
I found this info. about using clean stored urine. Looks good as long as the temps. are 90-100 using body heat and warm up packs.
"Real urine is only good for about 4 hours or so at room or body temp before it starts to spoil and smell quite foul. But you can store it for up to 1 year if it is frozen or 30 days maximum if it is refrigerated. When you warm it up to the proper temp of 94-100f... be sure NOT to use a microwave, as that can easily get it way too hot... and preferably let it thaw out in the refrigerator overnight first. The best way to warm up a frozen/refrigerated sample is with hot water. Place the sample in its zip-lock bag, condom or glue bottle in a bowl and cover it with hot water. Depending on how hot your water is, you can get a sample from frozen to over 100 degrees in about 5 minutes. Of course that's too hot, but it's easier to cool it off while driving to the test than it is to make it warmer."
anyone have experience with this?
