well folks today is july 8, a full two weeks after using q/fix 5.7, it obviously has worked! as with everything else FOLLOW DIRECTIONS AND STAY CALM IT WORKS!!! i have already purchased another bottle to await my next random. i kept the empty bottle and have been doing some testing with it. i filled it with water, let it sit over night and want to know how it will take to come up to the required temp(94-100). this is what i have found. if i put the bottle in my sock it will heat to 94-96 degrees and hold after 1hr 30mins. if i place in my crotch, it is slightly warmer at 98, and only takes 1hr or so. this is also taking into effect that i live in midwest as a road worker, and the temp is fairly warm at this time of year, and keep quite active at work, lifting, walking etc.. but i only work spring thru fall so its a wash cause i am laid off from dec-apr. i was just wanting to see if i get caught w/out a chance to microwave how long i needed b 4 it was at required temp. i hope this comes as helpfull, and like i said i have tried everything to pass a drug test in the past when i was a daily heavy smokr and found nothing worked till now. well off i go to celebrate and not worry about the pee police!
