Just had a drug test at the peak f my cycle. Test, Deca and Tren. The interesting part is that I was also cycling Ritalin. Scared the hell out of me that they would detect it. Nope. This testing was done by the police lab for a job that I got that was affiliated with the inpound department for the police. The testing was quite extensive. I knew for sure I was dead meat......... But, no. Don't worry.........
