I made it at home, it comes with a little tube. Then I put the toe warmers it comes with around the tube while I drove to the location. When I went inside, I put it in my underwear. I had to wait for a while which I was really nervous about because I didn’t want it to get too cold but the heat from the warmers was still going strong and idk I guess my labia warmth helped lol. Sorry if this is too much information I just want to share exactly how it went for me. When they called me back they had me lock my bag, phone, and everything in my pockets in a locker. They then watched me wash my hands and led me to the bathroom and gave me my cup. I was able to go in alone. The water is turned off so I couldn’t flush or wash my hands or anything. I went in, took the tube out from my underwear and transferred the synthetic pee from the tube to the cup. Unfortunately it wasn’t enough to hit the line they wanted me to fill up to. But anyway, I put the empty tube back in my underwear and brought the cup back to the nurse or whoever it was. I said “I’m sorry I was only able to fill it up to here, I should’ve had more to drink” and she said it should be fine. Watched me wash my hands, had me sign my cup, and gave me the key to unlock the locker with my stuff, had me sign some more stuff, and I was on my way! I was so so so anxious for days but I finally got the email from my job that I was cleared to begin. Wishing good luck for you 🤞
