I know the reports of dmaa, dmha, ephedrine and stuff like that causing false positives are pretty conflicting, but I wanted to see what you guys think here. So, the other day, my coworker gave me a sample pack of 1up nutrition pre workout and I took it yesterday without thinking anything of it, but today, I had a job interview and got an offer pending drug test results, and they took a saliva sample right there in the office. The only ingredient I'm thinking might cause false positive is e. Jarensis extract. Anyone have any experience with this?
I'm mostly concerned because if there's a chance of a false positive, I took the pre just about 20 hours before the test so the concentration would be pretty high, I would imagine.
