Straight up depending on who is testing and how. I use to carry the fake piss when I had a solid job. I carried it on my truck, another guy had it strapped to his leg all day and every day.
I guy I worked with told me to use the shit from trails. I said he was full of shit. He used it right when he got the job, it works. Really fvcking works. I don't know which panel # of a test it was. But, it was standard test we both took to get a job.
