ok so im wondering how to keep urine fresh, and how long it is good to use for a drug test-

example, if i have a clean urine sample- should i keep it in the refriderator? freezer? etc.

and how long will this sample last and be effective?

you're screwed because a lot of urine tests have indicators not only for drugs but for temperature. in other words, if your piss temperature varies too much from the average person's, they'll know immediately.

A good way to get around this obstacle is to fill a condom with the urine and tape it either under your balls or the inner thigh. It should stay pretty warm, if youre a girl then I hear its better to put it in teh pussy.

im not so much worried about temperature becasue i have a box of heating pads and i plan on doing as you say, filling up a condom with the urine and taping it, inside the heating pad, underneath my balls


what im mainly concerned about tho is how to keep the sample fresh-- the test is on friday, and im probably going to collect the sample on thursday...

The fridge will do fine for single day storage.

thanks, i appriciate the info-
any idea for how many days it will stay valid with this method (refriederation)?

Urine stored at 4°C (39.2°F) will remain fresh for up to 8 weeks[1][2], but obviously, the sooner it is used, the better.

Urine stored at -15°C (5°F) will remain fresh for 4-6 months[1], again, the sooner the better, obviously.

I've been told it's pretty decent in the fridge for a week or two, but any longer you should probably freeze it.

thanks for all the info guys i appriciate it

now for a noob question-- any idea what the average refridgerator is kept at--- im guessing mine has got to be at least around 40F

get a thermometer.

You should probably label it too. ;)

the test is on friday, and im probably going to collect the sample on thursday...

Then what is the point just wait tell Friday and save yourself the hassle.

I was going to say this.

Fortunately for you, "the average refrigerator" also comes equipped with a freezer, which is stays at a much cooler temperature (28-30F or so); would be your best bet.

But one question, if your test is Friday, and you think you're gonna have clean piss on Thursday, why the fuck couldn't you go one day and wait till Friday to save you all this hassle? Is your "drug problem" that bad? If so, you should seek help immediately.
