What Is Quick Fix Synthetic Urine?

Published Mon, April 25, 22

Swapping your pee with synthetic urine is one way to dodge a drug test. As one of the most popular brands of synthetic urine, it’s natural to wonder what Quick Fix is, how to use it, and if there are any better alternatives. In this guide, find out if you should use Quick Fix, and discover answers to questions related to using synthetic urine.

What is Quick Fix urine?

Quick Fix is a popular and inexpensive brand of synthetic urine. It is designed to replicate the properties of human urine effectively enough to fool common urinalysis drug tests. In practice, Quick Fix can be somewhat tricky to use, and it doesn’t compare very favorably to some of the more expensive options that are out there. As the name suggests, however, when you’re in need of a rapid solution to a drug testing problem, Quick Fix will often do the trick.

What is Quick Fix used for?

Quick Fix is used in the context of drug testing as a believable substitute of human urine. It contains all the substances present in normal, healthy urine and does not contain any of the chemicals you may have been using that drug tests screen for. You can’t just use Quick Fix out of the box, however, and expect it to work properly. A few additional steps are required to make Quick Fix trick a drug test.

What’s in Quick Fix urine?

Quick Fix synthetic urine consists of water, urea, creatine, uric acid, and other ingredients designed to balance pH or mimic the density of real urine. Some alternatives to Quick Fix, including Clear Choice Sub Solution, mimic human urine more closely by including trace amounts of a variety of additional substances. Usually, though, the medley of ingredients included in Quick Fix replicates urine closely enough to get the job done.

How do you use a Quick Fix kit?

The official Quick Fix instructions include the following steps:

  1. Check the batch code on your synthetic urine bottle to make sure it has not expired.
  2. Activate the hand warmer included with your Quick Fix kit. Set it aside for later.
  3. Vigorously shake your Quick Fix bottle, and remove the safety seal. Note that newer Quick Fix bottles are designed without this seal.
  4. Microwave the Quick Fix bottle for around 10 seconds. The temperature strip on the side should now sit between 94-100°F
  5. Attach the hand warmer to the Quick Fix bottle using the included rubber band. Keep the hand warmer in place until it is time to provide your urine sample.

How long do you microwave Quick Fix?

The manufacturers of Quick Fix recommend that you heat your bottle of synthetic urine in the microwave for no more than 10 seconds. Microwaving Quick Fix any longer than this duration could make it hotter than real urine or damage its ingredients.

How long does it take for Quick Fix to heat up?

In a microwave, it only takes around 10 seconds for Quick Fix synthetic urine to reach between 94-100°F, the ideal sample temperature for real human urine. You can also heat your bottle of Quick Fix with the included hand warmer, which takes longer but provides the same results.

What happens if Quick Fix is too hot?

If you accidentally raise the temperature of your bottle of Quick Fix too high, the drug testing laboratory inspecting the sample will immediately determine that you are using synthetic urine. There is no valid excuse for human urine being warmer than around 103°F—even if you have a fever. Make sure to check the temperature strip on the side of your Quick Fix bottle to verify that it is within the acceptable range.

How do you read a synthetic urine temperature strip?

The temperature strips provided with bottles of Quick Fix and competing brands of synthetic urine are generally quite simple to read and understand. These temperature strips provide values in fahrenheit on the top and celsius on the bottom, and a dot in the middle indicates where your synthetic urine falls on this scale.

Instead of providing the full number for each interval, Quick Fix temperature strips simply start with “90” on one side and end with “100,” and values of 2, 4, 6, and 8 are provided in-between to determine where your synthetic urine falls between 90°F and 100°F. Any temperature within this range is acceptable, but it’s recommended that your synthetic urine be between 94°F and 100°F for the highest chance of fooling laboratory equipment.

How long does Quick Fix last once opened?

Quick Fix is rated to last two years before it expires. The shelf life of Quick Fix synthetic urine should not decrease considerably after you open the bottle. Just make sure to close the cap again tightly, and consider keeping your synthetic urine in the refrigerator to prevent bacterial buildup that does not naturally occur in human urine. 

How do you store Quick Fix?

Keep your Quick Fix synthetic urine in a cool, dark place that’s out of direct sunlight to avoid damaging its components or reducing its shelf life. Stored properly, Quick Fix should last for around two years.

What are some alternatives to Quick Fix synthetic urine?

Some popular alternatives to Quick Fix include:

  1. Clear Choice Sub Solution: The best (but most expensive) option, which very closely mimics human urine.
  2. Clear Choice Quick Luck: A cheaper version of Clear Choice that is almost exactly the same as Quick Fix.
  3. Testclear: A powdered synthetic urine option that some users claim works better.
  4. The Urinator: A high-tech, expensive option designed to prevent genetic discrimination—don’t tell them you’re buying it to pass a drug test!

Passing a drug test FAQ

To finish up, we’ll answer some questions related to passing a drug test:

1. How long do you need to be clean to pass a urine drug test?

It’s usually necessary to stop ingesting a substance you’ve been using chronically for at least 30 days if you want to pass a drug test. That’s because most of the chemicals tested for in urinalysis store in your body's fatty tissues for around a month. If you’ve only used a substance a few times, though, it might clear your system in as little as a week.

2. Do you get patted down before a drug test?

No, it is very uncommon to be patted down before taking a drug test. The only instance when this might not be the case is if you’re drug-tested while already incarcerated. Companies like LabCorp that are contracted to provide drug test services do not pat you down before asking you to provide a urine sample.

3. Can you heat up old urine for a drug test?

Yes, it might be possible to fool a drug test using an old urine sample. If the sample is too old, however, its chemical consistency will have changed to the extent that it will not show up as normal urine in testing. If you decide to use old urine to try to pass a drug test, just make sure to heat it up to body temperature first.

4. Can you use cold urine for a drug test?

No, one of the primary diagnostic tools used to determine the admissibility of a urine sample is a simple temperature check. To be accepted by a diagnostic lab, your urine sample must be between 90°F and 100°F. If your sample is outside this range, it will be rejected.

5. What temperature does urine have to be for a drug test?

You are most likely to pass a drug test if your urine sample reads between 94°F and 100°F. Most testing labs are required to accept samples that read as low as 90°F, however, to account for the natural cooldown that can occur as the urine is handled. Aim for around 98°F to accurately mimic human body temperature.

6. How long does your urine stay warm?

Urine cools down at the rate as any other water-based fluid. Kept attached to a hand warmer and inside your pocket (as recommended by most fake urine providers), a urine sample will stay at the correct temperature for up to five hours. Left out on a cool surface, however, a urine sample will reach room temperature within around 30 minutes.

7. Will urine stay warm in my pocket?

Urine will not stay warm enough if it is simply placed in your pocket. You must attach a hand warmer to your urine sample if you decide to transport it this way. Another option is strapping the urine sample to your groin, placing it between your breasts, or placing it on another part of your body that is surrounded by warmth.

8. Can eScreen detect synthetic urine?

An eCup eScreen is an instant drug test designed to detect the presence of a handful of illicit drugs. Providing results that are far less accurate than lab diagnostic tests, an eCup is not as likely to determine that the urine sample you provided is synthetic. Just make sure your sample is heated to body temperature.
