I wouldn't suggest synthetic urine. Urine tests are very particular, and depending on the reasoning for your drug test, you could have someone standing in the room with you, or for jobs, they usually check the urine sample right after you urinate. Pee is typically warm, and synthetic urine is room temperature. If you provide them with a sample that's either cold or room temperature but not hot, they'll be suspicious of it being fake, and there are actually tests they can perform to see if the urine is synthetic or not. The best way in my opinion is just doing a detox. It can clean out your system in an hour and let's you test clean for 6 hours after. That way, you don't have to worry about any factors other than urinating when asked to, and taking the detox. There's a few brands but I recommend ones from PassADrugTest.com It's worth checking out and will help you out.
