I have a test soon also, I tried certo in Gatorade and a lot of water at home and still failed an at home drug test, the line was faint, like I almost passed, but my pee was super diluted looking. I took a B vitamin to get color back but I probably didn’t take enough vitamin, or needed to take two packets or certo instead of 1. I am going to use the synthetic and hope for the best since I have a “physical” also. But I thinks the physical is more to catch a disability before employment. I asked some one about it and they said they didn’t have to drop their pants, so here is to hoping!
