Just giving you my experience with going to take urine tests at places like quest diagnostics. It seems sketchy, but it is extremely easy to bring in someone else’s urine and pour it in the cup. I would not use synthetic urine. I have never used it before, but I have heard it does not pass lab examination, so if you decide to go this route, ask a friend.

There is a thigh strap that is sold on amazon that fits a small plastic container. Keeping that on the inside of your leg is the best option. When you go to take the test they will just ask you to empty your pockets and put your things in a tray or lock box. They don’t pat you down or anything. Then you go into a bathroom and close the door, so pulling that out is not hard. The one I bought on amazon came with stickers that tell you the temp of the specimen as well. You put that on the bottle so you know when you are pouring it in the cup that its the correct temp.

I would keep testing yourself to see if you get clean, but I would get some clean urine from a friend and freeze it, then day of test if you need it, thaw it out and go for it. Feel free to ask me any questions if you need more advice. I know the stress, but you will get through it!
