This thread is awesome! It's actually kinda what I was coming here to read.

One question I have for substitution through synthetics: how easy is it for a lab to check whether or not the urine is real or synthetic?

Here's where I'm at. I'm 6'2ish, and 220-230. Out of shape, and have an incredibly slow metabolism (I typically only eat in one interval per day, so my body conserves at lot). Smoke somewhere between two and four bowls a day (about an ounce every 1-1.5 months), and have been fairly constant for the last 5 months. Due to a corporate restructuring, my department is being absorbed into four others. To move to the part of our business and give me the opportunity to get promoted the quickest, I need to take a drug test.

The drug test would probably be in about 1 month, and I plan to quit smoking after this Friday. I know my own urine won't be clean by that time, so I am buying a whizzinator online tonight (or tomorrow) to help me sub. The company we go through is Quest Diagnostics, so I know I won't be observed....but better safe than sorry.

So, question time for those who are more knowledgeable about the Sub Club than I:
1) Is it easy for a company like Quest to identify and report synthetics? The test I would need to take is 10-Panel (have already started shaving my head in case it moves to a hair follicle default) for what pertinence there is.
2) For the whizzinator, there are two choices: either freeze-dried synthetic urine, or their still hydrated version. Would there be a functional difference between using the two?
3) My roommate used to smoke as heavily as I, but quit 3 months ago, plus is very active. I know I could get him to give me some urine (we've been buddies for 15 years), so would it be more advantageous for me to ask him to provide my sample? (I would prefer not to ask a buddy for their piss!)

Thanks for any replies that come up! And sorry if the questions are answered somewhere else, I tried searching the forums and couldn't find anything.
