Alluprbdy,
It would be helpful to understand what type of drug test you're taking - standard five panel, eight panel, 12-panel - are they adding specialized testing for certain molecules? And if I read correctly this is for work - but they're allowing you to submit a home sample (that's highly unusual). At best, they'd have you go to a testing center and provide an "unsupervised" sample - meaning you can pee without an attendant observing the full process. One of the first things a testing facility will do is check temperature range - which already makes your home sample invalid - because by the time it's provide the temperature will be out of range.
Also, using a swab of bleach to your wee-wee (sorry can't tell if you're a boy or girl and don't want to accuse you of having a V-Jay-Jay and demasulate you!) - will be picked up on the nitrate count. Any adulterants will elevate the nitrate count and be an instant red flag. Since I don't know what you're being tested for - it's hard to recommend strategy. But since this is a home sample is it possible to have a clean friend or relative provide the sample? That would be most ideal in this situation.
Standard testing will always test for THC - and if you're actively using - you're totally fucked because that requires three weeks of abstinence (and a lot of flushing the system). Anything else you're taking where you cannot produce a valid prescription can be diluted significantly by drinking water w/lemon - alternating a Gatorade here and there. And by a lot, I mean about 200 ounces in a 24-hour period. Believe it or not, you can die from excessive water consumption - so if you're extremely petite you may want to drink less. (I'm 5'4" 128lbs and safely drank 200 ounces daily during the summer when I was being randomly tested.)
Good luck.
