I planned on having my girlfriend urinate in a cup before she leaves to work and keep it in my car daily so when the time comes I just put it in the whizzinator bladder and strap it on and good to go.
Keeping your GF's sub pee in your car daily will not be a good idea. Human urine needs to be refrigerated or frozen until ready for use. For your particular situation, consider a synthetic sub since it can be stored at room temp. Just be sure to keep the synthetic sub away from direct sunlight.

Human urine is only good for 3-4 days in the fridge, and up to 1 year in the freezer.
Burnt Toast Reviewed by Burnt Toast on . Need to pass drug test... So I am working as a temp at my job, but am getting hired on very shortly. I will be asked to take a random drug test at a different location, not at my job. Approximately 3 miles away. I just purchased a whizzinator for peace of mind. I would have not smoked for about 2 1-2 to 3 weeks, but just don't want to take any chances.
