As long as the labs are following protocol its perfectly safe. There does appear to be one lab in Oregon that is not following protocol, but all the big labs,Qwest and Labcorp, will get a pass on synthetic no proble,
killerweed420 Reviewed by killerweed420 on . General synthetic question So, what is everyone's thoughts now on synthetic vs. Dilution? I know I won't pass with my urine, are synthetics really that reliable? Does it vary at different labs with differet tests, or are most pre-employ tests the same? Just took a split test at qwest with synthetic and really concerned. Thanks for ANY info. Rating: 5
