I know that I can be pulled for random tests any time at my job (a job that i love) so I had bought about 3 bottles of Ultra Pure Synthetic and carried them in my bag every day for several months. never exposed to direct light (other than moving in and out of my bag quickly in rooms with artificial lights). i'd heated and cooled several times. once i ordered adulterant test strips online and tested a sample from one of the bottles, and it passed everything.

Anyway, I used Ultra Pure Synthetic for a lab test in Louisiana in August 2012. I had an hour to drive myself over to the lab. As soon as I found out, I opened and shook up one of the heating pads. I took some hot water from the instant tap on our office coffee pot and carried a large styrofoam cup of it out to the car with me. i spent a few minutes dipping 2 of the bottles into the water then pulling them out and shaking them up to evenly distribute the temperature. i made sure to not actually dip the heating strips into the hot water so that they wouldnt get messed up in any way.

I wanted to start at a high temp bc i figured time would allow it to cool, but it could be difficult or impossible to heat up at the last minute. also, i figured transferring it to a cold container and blank temp strip would probably drop my reading a few degrees. so once i got the bottles up to a uniform temp at or just above about 100 degrees, i rubberbanded the heat pack around one of them, then stuck one 2-oz. bottle in each bra cup. made sure they were secure enough to where there was no chance of them falling out and no noticeable lumps or anything visibly weird.

i went into the building, nervous as hell. i made sure i seemed calm and casual. i showed my drivers license, filled out a short form, and went directly into a completely private bathroom with a locking door. they told me not to turn on the water or flush the toilet at all until i'd handed over my sample. they showed me where the cup had to be filled up to, and it was pretty low, about 2 oz. I had the privacy to take my time and spread out so i too both bottles out of my shirt/bra and set them on the ground and set down the sample cup i had to fill. i calmly poured one whole bottle in and a little out of the other one. i made sure the temp strip was solidly in the 90 to 100 range, a little high to allow for cooling. i screwed the caps back on my bottles and put the empty bottle in one bra cup and the semi-full bottle with rubberband and heat pad back into the other bra. i checked around and made sure i wasnt leaving anything behind. i peed in the toilet and wiped with toilet paper and threw that in the toilet. then i went out handed over the sample and left. i never heard anything back and it's been 3 months so i'm sure now that it went fine. i was pretty nervous for the first week or so but honestly as soon as i was done it was a pretty big relief already.

i spent hours and hours reading things like this and found way more questions than answers - so i just wanted to share my results and give some other people peace of mind. if you know you will get a private room (i casually asked around at work about how the place was - and i think it's reasonable to refuse to be watched peeing anyway), then id definitely recommend doing this. and if you know what lab u will be going to, you can go on their website and read what type of adulterant tests they do. most people just test for additives (like bleach, etc.), SG, creatine, pH, and temperature - all of which are taken care of by ultra pure. if you handle the switch and temperature correctly, then you should be fine. the only things i've heard of failing for are not having uric acid and that is not typically included in adulterant tests. also i switched to ultra pure because i have heard that it is one of the only brands that actually does include uric acid, but it is not heavily advertised as such so i'm not positive about that.
