I've used strip on two occasions before. Once to get a job, then again 7 months later for an injury/ mandatory drug test. Ann hour and a half before I was tested for the pre employment screening, I drank strip 6.5 ounce bottle. I drank 64 oz of water and urinated 3 times to flush the system. I was worried about having clear urine, so I drank a rockstar for the vitamin b-12. That made my urine orangeis yellow. I passed.
Second time was during my one hour lunch period. I ran home, drank the strip with 64 oz of water, and passed my drug test an hour later.
Im about to go do it again. I think it's reliably.
