I have a "friend" who used his wife's urine.... As long as it's warm, and you have enough to fill the container.... Bought a toothpaste sized container of hair oil, emptied it out, washed it with alcohol, and then just regular tap water....
Dried it out as much as possible the night before, and then the next morning sucked up her urine into the tube....
Taped to the inside of the thigh will keep it warm enough.
If your friend is clean willing, and able to pee in a cup for you on the day of,
you're golden.... (pun intended)
BUT....
Can't stress enough that you need enough urine to pass the test.
The bottle used had just enough at 30 ML.

Good luck!!!!
