synthetic vs. real

So I have a whizzinator which I havn't used for a long time. I've been clean for about 8 months but I slipped up and it is very possible I will have to bring it out again on my upcoming UA.

I have synthetic urine which I was planning in using however I also have the option to use real urine but it would be from my female friend who I know is clean

My question is this: Which is the better choice? synthetic urine, or real urine from the opposite gender? is it possible they will know it is synthetic? is it possible they will know it is female urine? thanks!

Also I'm not sure if the temperature strip is still reliable. I was wondering if anyone knows where I could get temperature strips or some other kind of thermometer. at a GNC or something? Walmart maybe? I don't think I'll have time to order one online... Thanks again

I would use the synthetic urine because it is always 100% effective if you get the temperature right. No they cannot tell if its synthetic. A donor urine sample would also be affective if you know this person is clean and you can obtain the sample shortly before you have to take the UA. It starts to go bad after 8 hours and I wouldn't push it past 6 just to be safe. They cannot tell if its male or female urine so your good there. You could pick up a thermometer at Walmart or Wallgreen's, I dont think GNC would have them.

Thanks. What kind of thermometer would I be asking for, just a waterproof one? know any brand names?

I bought the childs temp strip (that flat thermometer that looks similar to the one on the quickfix bottle) at a Walgreens... it worked perfectly. It was just a couple of bucks. I couldn't find it at WalMart.
