hey guys just got finished checking my quick fix with a one step specimen validity test and as always its good to go. I work at a facility were the company not only does monthly randoms they always send it off for gas test. and me and a couple of my buddies have been subbing with the fix for 3 years. there is only a four day period that names our drawn for random and if you win the lottery its one of those go to medical dept and take a test before they close deals so its pretty cool. i usually half way dillute those 4 days just to be sure, but the nurse always makes us close the door because she is embarrassed, but im sure if you got busted they would supervise you. also we get one freebie where we can come back after we get a clean test but after that if you get busted your gone. i truly believe that they hate having to even do it but company policy makes them drug test us for safety purposes i guess. oh well anyway my batch # on the qf i just tested is f11n-08 and like i said its ready for the hand warmer.remember in life you can take control or you can be controlled. this guy stating that his qf let him down obviosly did not check it out and just went for it wich is not a good idea when your livelihood is at risk test your batch be confident it your specimen!!!
