I'm posting this thread because after researching how to sub urine for a test, I realized I was not able or comfortable with some of the options out there. So I figured I'd post this to help any girls like me out there and let you know how I successfully subbed urine. Here are the common methods I've read and why I didn't do it: 1. Hide the substitute in your bra. The truth is, I have small boobs. So when I tried to put it under my boob in my bra, you could clearly see it and stuffing the bra didn't make it any less noticeable. 2. Hide it inside your vag. Okay, there are two reasons I wasn't doing this one, it didn't seem sterile to me and sounded quite uncomfortable. I saw this proposed two ways, either with a condom or with a container you could fit inside of you. I'm an overthinker so I decided the condom route wouldn't be good because it could get messy and I'm really clumsy and the container inside was just a sterile issue for me personally. If you've succeeded in doing it this way, awesome! I'm not knocking it. It's just not something I've tried or am willing to try. But I've read some great success stories. So what did I do? Okay, the first time I ever subbed was a year ago (May 2011). It was quite the scary experience because I had smoked a week prior and was unaware my work would be giving random drug tests. (It was told to us in orientation they would but they didn't actually start regularly randomly drug testing us until a year and a half after working there.) The HR department gave me an hour to take the test and I was unprepared. Luckily, I had a coworker who had some synthetic urine so I was able to use that. As we went through the options of where to place it, I ended up placing it on my ankle. I used a oversized sock to make it stay in place and had the heating pad rubberbanded to it. My pants flared at the bottom so it wasn't noticeable or bulging. I wasn't searched or anything. It worked! I passed my drug test. (Side note, the lab was QUEST if you were wondering.) Today, I went in for a pre-employment drug test for Target. I used Quick Fix. This Target uses Lab Corps. What I did today was different. I placed the sub in my underwear like you would a pad. (I actually wore two pieces of underwear, the first one being normal panties and the second being tight boyshorts to secure it in place.) I ended up wearing a dress (but this will also work with skirts as I tried this method on them.) I chose a dress because I thought I would look less conspicuous as my ankles and everything would be showing. Do not wear anything form fitting. I tried this with a pencil skirt and you could see a bit of a bulge. Wear a dress/skirt that is loose. Anyways, I was able to take the test just fine. I heated up the syn urine and kept the heating pad on it until I got there. It was at a hundred degrees. While I was waiting to take my test I did sit on a very cold seat, so by the time I took my test the temp had dropped to about 94 (which as we know is still valid.) This is just something to keep in mind. I don't know if I passed, I will update if I do, but I was able to successfully sneak it in, which was the point of this thread. If you have any other methods for females that you'd like to share, please do!
