Normally, clean urine is only good for four hours at room temperature, or eight hours in the fridge. It can be frozen, and is best placed in the freezer immediately after collection.

How to Store Pee After Collection
If you have a vacuum seal, the clean urine can be kept at room temperature for several days, as long as it is kept out of direct sunlight. 

You can keep it in the fridge for up to six months and in the freezer for one year.  When the sample is removed from the vacuum seal, it is good for 30 days in the fridge and six months in the freezer.  Don’t leave it at room temperature for more than 18 hours.

Preparing Stored Urine for Use
When you are ready to use the clean urine sample, bring it up to temperature by running it under warm water. Shake the sample well so that any particles dissolve. It should be thawed slowly and at a constant rate to stop crystals from forming.  If they do, you can filter the sample.

Urinalysis is the most common method of drug testing.  It was the very first laboratory test to be developed and dates back over 6,000 years. Urinalysis was first introduced as part of the routine physical examination in 1827. In drug testing, urinalysis will typically test for the drug itself and for the substances produced by your body when it metabolizes the drug.

Drugs that will often show up in a urine drug test include anabolic steroids, barbiturates, amphetamines, benzodiazepines, codeine, morphine and other narcotics/opiates.

This is what I do - worked 3 times for me so far (I am a girl and this is is a lot easier for us women, because we have special, uh, "crevices" to keep the pee pee warm in - haha guys!).

Go to any store where they have bins of empty spray bottles (Sally's, Target etc.) and pick a small long one, but enough to hold at least an ounce or two. Put the pee in it, and fasten a saran wrap lid on it with a tightly bound rubber band.

Keep a bobby pin in your hair with the rubber tips taken off to make the ends sharper. Slide the bottle up into your va-jay-jay with the saran wrap side down. It might be a tad uncomfortable, but it keeps it at the perfect temp because it's inside your body and it's all moist and steamy up there which makes it PERFECT.

If you are going to be supervised (which they don't normally do unless you are a repeat offender) make like you are itching your head, and grab the bobby pin and stab the saran wrap. It will tinkle out. Make sure you push the pin into bottle so they don't see you with it afterwards.

If nobody is going to be watching, just take it out, give a good shake and empty into the cup. Make sure you stash the saran wrap, rubber band and bottle in your panties. They check the trash and don't allow you to flush or use the sink.

As for storage, it will keep for up to a week tightly-sealed in the fridge. Put the container of pee in a brown paper bag to keep any and all light out - light will break it down and cloud it up. I use a friends wee each time.

I think that all this advice is great. Thank you. I just took my last pill and I need to have it in my system when I go to the doctor next week The last time I went to the doctor I kept in the fridge for 3 days and it worked fine.

I warmed it up, kept in a condom and passed. They send their test to a lab and it cost me 100.00 and they didn't detect that it was 3 days old. But now I will freeze it because my app. Isn't until next week. I will let you know how it works out. Wish me luck!

If stored in an air-tight container, urine can be stored in a freezer for at least three months before the taste is affected to a significant degree.  But believe me, it's MUCH better fresh and warm.

I would say you cannot freeze urine because it is supposed to stay very warm, like body temperature or even warmer. So if your going to use it for a drug test or something I would not suggest freezing it because they will probably be able to tell.

First of all...ew. Secondly, why would you want to save waste? Thirdly, if your intent is to pass a drug test, just stay clean, and your worries are over. Besides, most, if not all agencies now require an employee to watch when your submit your sample, so trying to trick them would not be in your best interests, as I know of several people who tried countless ways of doing this, and failed every time. Needless to say, they are not free. Be safe...

Stretched it over the top of the tube - now i also took a very very small mushroom shaped rubber plug(which i got out of a printer ink cartrige refill kit)stuck it inside the nipple threw the hole so it could not come out but could be pushed in to let the urine flow out - then with the urine inside the tube secured the nipple with a rubber band and lots of black tape. Stuck it in the freezer for months even took it out a few times thawed it out and didnt need it so refroze it then this one day
