Took test today at a little hole in the wall pathlab. I used the pretestedurine.com sythetic setup:

Small IV bag, vial of synth piss, hand warmer, temp guage, specimen cup, instructions.

I set up everything as described in the directions about 1/2 before leaving, and the lab is about 25 min from my home. Taped it up under my armpit.

Got to lab, waited about 5 min, went into office, handed cup, said no sink, no flush.

Went into bathroom unsupervised (and closed the door completely). Took out the business end of the IV, opened the clips, provided a 95 degree sample (nice and yellow too), signed some papers, stuck a sitcker to the bottle (part of the whole chain of custody thing), and off I went. I beleive that the hard part has been done. Once I get the final news I'll be sure to update this post.

Peace!
