I have not tried it myself but in my Internet travels I have heard it works just as well as QF and some say it may even be QF repackaged.
jeffman Reviewed by jeffman on . Dr. Greens Agent X synthetic I got a random UA on friday, luckily I had some synthetic urine on hand. The only thing that really makes me nervous is that the Dr Greens Agent X had little particles floating around in it even after I shook it up. I just bought the synthetic urine at a head shop a couple weeks ago but i dont know if it may be too old. The pee is being sent to Kroll laboratory for a Immunoassay test I would just like to know if anyone else has ever had the same problem, or knows if it will be alright or not. Rating: 5
