My point is, DOT is easy to pass if you are doing it with the sub route. Just make sure you practice the temp being 90-100 degrees. I'd also recommend the larger product, because since it is a split sample, 2 oz might not be enough.
DOT requires only 45 ml of sample. The sample is then split 30/15. With that being pointed out, 2 oz (60 ml) is enough for the U/A.

i mean what exactly are they testing for with the urine? they test for the 5 panel of drugs obvi but are they doing additional testing, like for creatine or whatever else?
Yep, creatinine, pH, specific gravity, excessive nitrites, high chromates, and the presence of pyridine and glutaraldehyde. As long as the synthetic is of a reputable brand, unexpired, and had been kept away from direct sunlight, you have nothing to worry about.
