I'm 52 years and I am a Medical Technologist. I work in the lab and test EVERYTHING! I've been doing it for 31 yrs and have been opiate, benzo cocaine addict the whole time. Advice I will give right here is Never say always and never say never. Strange things I've seen in the last 31 yrs Want to know how we got around TIMERX! in the Eastern US anyway. That be me. I/ll not go into the chemistry behind it but in the lower threads I will. Peace BT out
