Nothing wrong with using somebody else's urine as long as you're absolutely sure its clean

What is better I have come to the conclusion that dehydrated human urine or frozen human urine are the best choices since there is a possibility of them detecting sythetic urine. I know that my poll showed that synthetic is the best, but the post that said that was over 4 years old. I assume the people checking have found out that people are using synthetic urine and they have a way to find out if it is good or not. I plan on using it very soon, so I am not worried about storage time. Dehydrated urine Rating: 5
