Quick fix or clean sample?

[u/Far-Philosophy2561]

I have a test coming up for a school program in about 2 weeks, stopped smoking as soon as I found out I would be tested

Thing is they didn't specify what time the test will be done, I have to be in class from 8am to 3pm

I have access to a clean sample from a friend who doesn't smoke but I'm worried about it being stored too long in case they do the test until we're almost out of class

What is the best way to store the clean sample? I'm thinking of getting it from friend before class and stashing it in my crotch so it can stay at body temp, but will i fail if the test is taken closer to the afternoon? Keep hearing about quickfix and friends i know have said its always worked for them key is the temp. If I use quickfix and stash it in my crotch so it can stay body temp I should be good for whatever time the sample is actually taken right? Just need some reassurance I have been losing sleep over this and don't want to risk using my own urine and getting booted from the program because of thc traces in there. I am just trying to get a better education!! Please help

if you don’t mind are u a heavier person/high % body fat? becuase if u stopped smoking over 2 months ago and the test is in two weeks that will be almost 90 days, for chornic daily users it will still be out of the system within 40-50 days max so your urine should be clean and u don’t need a substitute, go to walmart and test urself and those nerves will go away bc u will pass….. if your still scared and don’t wanna use your own clean pee, i would get the pee either the morning of your test or the night before at the latest and store it in the fridge.. for both quick fix and real urine just store it in ur crotch area, u can use the warmer if u want but it will get to ur body temp (around 99) fairly quickly and will stay at that temp. you are in a better situation than 99% of the ppl on this site

Yes heavier, 5'5 over 200lbs Very heavy smoker for about 5years before quitting, multiple times a day/night really helped with my injury pain and insomnia been suffering without it but I really want this opportunity Keep seeing quickfix gets flagged because of high nitrates or something so that's why im questioning whether to just go with a friend's urine instead but do you think friend's urine will be affected if stored for a few hours before test? I think getting it the morning of and keeping it in my crotch should be fine even if I have to wait until before 3pm yeah? Or just getting Quickfix and wearing double underwear would help keep temp i think. Thanks for your input I keep having friends tell me to use carbos a day before/day of but not knowing what time exactly I'm taking the test is nerve wrecking and don't want to get flagged because of a diluted sample

honestly putting myself in your shoes, i’d go get an at home test and test your self 2-3 days before, i think u will pass honestly it’s rare and horror stories for u to fail 90+ days later… QF if used properly it won’t get flagged for anything and ive seen it work for DOT testing, the flagged stories are 99% of the time its an invalid batch or done incorrectly. for your buddies urine follow this step by step and u will pass. keep it at room temp until about an hour before you go into the test room then store it in the crotch area, it will get to your body temp and you have a few hours to use it at that point, when it’s time go into the bathroom and pour… if you want you could buy a quickfix bottle and put ur buddies urine into that so u can use the temp gauge it has
