Synthetix5 review

I read some mixed reviews from reddit users regarding sythnetix5 and synthetic urine in general so i wanted to make my own post, specifically for employment with the Postal Service. I have worked for USPS 2 times prior to this and I failed one drug test a couple months ago using my own urine. Barred from employment for 90 days and after the 90 days I hadn't been hearing anything back from the Postal Service which I thought was weird because I have a high test score and I have always been invited to interviews and offered almost every single position I applied for. Thinking that USPS hiring managers were able to see that i was previously barred, I thought i wouldn't hear back and smoked a couple times. Got called in for an interview 3 days after I had last smoked and the hiring manager tentatively offered me the job on the spot knowing that i had the highest test score on the list and previous experience with USPS. I immediately started going to the gym every day and using the sauna, drinking water and cranberry juice but I was continuously failing at home drug tests. When I was officially offered the job and received emails to consent to the background check and schedule the drug test, I stalled as much as possible (3 days to schedule the drug test and 5 more days to go in and take it). Still couldn't pass using my own urine so i bought synthetix5 at a local smoke shop. The employee said she has a customer on parole that regularly uses it so i decided to try it over a detox drink that seemed very complicated to get proper results.
Heating the synthetic urine properly seemed like a slightly difficult task. I do not own a microwave so I put the bottle in a mug of hot tap water. Every time i would pull it out the temperature strip was still black. When i decided i would give up on the water and try stuffing it in between my thighs i saw the temperature strip at 92° after sitting on the counter for a moment. Not sure if the water heated it up too high to read or if the water messed with the reading but when i saw 92 i attached the heating pad (which did not feel warm at all at first after shaking it over and over despite the instructions of shaking for 5 seconds.) With the heating pad on and the bottle sitting inside 2 layers of thigh high socks for 25-30 min, the temp reached 100°. For the next hour i went back and forth removing the heating pad and keeping it against my thigh. Without the pad it cooled to 92°-94° pretty quickly and with the pad it heated up to 100°-102° pretty quickly. Decided to keep the pad off while i drove to the clinic and reattach before i went inside because i would have no way of heating it inside but could maybe stall to cool it or use toilet water. I had to wait over 30 minutes to take the test and by the time i got into the bathroom it was about 104°. The test facilitator was standing directly outside the door so i knew i couldn't remove the heating pad and risk making suspicious noise so i just poured the hot synthetic urine into the testing cup and waited maybe 45 seconds to see the test strip on the cup show green right in the middle (one end said 90 and the other said 100 so i assumed the middle was the correct temperature). The facilitator looked at the temp strip and accepted the urine and I just got a call from the hiring manager saying I'm clear to start work next week.
I wanted to make this post specifically for USPS because they run a lab test on it and i wasn't sure if they would be able to tell if its synthetic. My word of advice is to be careful not to heat it too high, over 104° because i heard that can burn the elements in it and cause a failed/inconclusive result. I used the basic synthetix5 bottle without the belt or bladder and just put it in my thigh high socks under a pair of leggings and a skirt.
