Last Updated on

quick fix 6.2 synthetic urine new formula - fake pee

There’s no shame if you enjoy a little recreational drug use every once in a while. All the science points to the cannabis plant being a pretty powerful and versatile medicinal herb rather than a dangerous drug. It’s been proven that it does more good than harm, but society still has a way to go before we can collectively accept that.

Even in 2023, many workplaces still deem drug testing mandatory. And while there are a ton of ways to cheat the system so your urine doesn’t test positive, not all of them are effective or safe—some of them even do more harm to your body than actual drugs you’re taking!

So if you need something that’s quick and easy to help you land that dream job, there’s definitely a product that can help. We found the best synthetic urine on the market today that guarantees that its formula is perfect; both in the own laboratory and in any modern-day drug testing facility.

Of course, with every and any fake pee product you purchase, knowledge is truly power. The more you know, the more you can be prepared. Read on to learn more about this holy grail of fake piss, Quick Fix synthetic urine.


What Is Quick Fix 6.3?

Quick Fix 6.3 is a brand of novelty synthetic urine. It is the best-selling fake pee on the market today. Artificial urine is typically used for passing drug tests, but some people also use it for other things like science experiments, pranks, animal or pest repellent, gardening, and, um… pee fetish stuff? Hey, we’re not one to judge!

quick fix urine reviewFor people who have drug tests coming up though, each and every batch of Quick Fix 6.3 pee has been pre-tested by manufacturers to ensure that it will give test-takers a passing result.

Quick Fix urine is unisex, which means it works for both male and female. And unlike the other synthetic urine products you’ll see on the market today—like the dehydrated or powdered urine kinds—Quick Fix comes as a liquid, ready-to-use form which ensures it’s quality and dilution.

It only takes 10-20 seconds to prepare, so the name is quite literally what it claims to be—a quick fix. Quick Fix 6.3 Plus urine also sells a whole kit of leg attachments, tubes, and a whole bunch of paraphernalia and trinkets you can use to easily fool clinic staff (for those times when they just have to be within 5 feet of you when you do your business, because some drug testing labs really do that!)

Quick Fix 6.3 urine and all its previous versions have multiple patents by the United States Patent Office. Each batch is lab-tested before it is sent out for delivery to assure the quality of the product.

Want to pass that dreaded drug test? we recommend using  Quick Fix 6.3 Plusa product with  a guarantee of 99.99% success rate. This fake pee is the best to beat that urine drug test when you’re in nasty situation. You can get it directly from their Official Site at a discounted rate.


What’s in Quick Fix 6.3 Synthetic Pee?

It’s not enough for Quick Fix to just look and smell like urine; synthetic urine has to have the exact same chemical composition as real urine if it’s going to get past laboratory analysis. We’re happy to report that Quick Fix boasts an identical chemical composition to genuine human urine, meaning it includes biologically accurate amounts of urea, uric acid, and creatinine.

But urine is more than just ingredients; it’s also about properties, so Quick Fix also has the same specific gravity and pH balance as human urine. The combination of all these factors is what you need to fool the testing instruments and get a pass on your test.

There’s only one other synthetic urine that can even come close to the chemical accuracy of Quick Fix, and that’s Sub Solution. And while Sub Solution is a great product, it’s also a great deal more expensive than Quick Fix.

How to Use Quick Fix Plus

Each bottle of Quick Fix 6.3 comes in a volume of 2-ounces, enough for just one test. It can fill a standard testing cup exactly. If you need more, you can either buy another bottle or buy the Quick Fix Plus version which gives you an extra ounce of urine and can fill up the testing cup a little over the required minimum.

As a precaution and in the anticipation of any spillage, purchasing the Quick Fix Plus version can save you some panic because it gives you a bit extra in case of emergency.

Two other things to keep in mind when you’re about to use Quick Fix pee other than just supply and amount, are temperature and method. Make sure your sample of Quick Fix is at the right temperature, and on the off-chance you’ll be supervised during your exam, make sure you’ve got a gadget ready to make it look like you’re actually peeing.

Has Quick Fix Ever Failed?

failed urine test sample

Quick Fix never fails…when it’s used properly. If you have an expired batch, or if you hand it in at the wrong temperature, there’s a very good chance of failing!

Here’s how to avoid those scenarios:

1. Temperature Issues

Here’s the thing that trips up some people and causes the most failures.

Human urine can range from 94 to 100 F. A lab has to take the sample if it’s within that range, but it’s also where most people get caught out by the techs. There are a few stories where a lab tech hasn’t even looked at the sample before rejecting it immediately for being the wrong temperature.

This is why a genuine Quick Fix package from the real website always ships with a heating pad, and why the instructions always stress to heat it up before you go in. So don’t risk buying your Quick Fix from an alternate source, the heating pad is a crucial element to passing the test, and if it’s missing or inspired you’re going to be left to your own devices.

Other factors affect the temperature as well. Remember to keep the bottle strapped close to a part of your body that can provide enough heat; the inner thigh or sticking it down your underwear works. Dress warm, especially if you live in a cold place; the more body heat you keep, the less chance there is of your Quick Fix cooling off.

2. Beware of Dodgy Vendors

You also have to be cautious of who you’re buying from. It’s very easy for someone who wants to make a quick buck to buy some cheap or expired fake pee, put them in boxes that look like the real thing, sell them on an online market like Amazon or eBay, ship them off to unsuspecting buyers, and disappear before someone figures it out.

There will always be untrustworthy types who prey on people with particular needs or wants. So it’s best to avoid this risk as much as possible, especially with your job on the line. When it comes to Quick Fix, or really any type of product made to dodge a drug test, it’s always better to buy directly from the manufacturer. This way you can be absolutely certain that you’re getting the real product.

Could Labs Spot Quick Fix Urine?quick fix synthetic urine review

The labs can catch you out in two ways: the lab techs inspecting your sample, and the lab equipment doing its job. If prepared properly, Quick Fix can get past both, which is why they make every effort to get their product like the real thing in every possible way.

The lab techs are your first obstacle, and Quick Fix is generally good enough to pass visual inspection.

But there are also some stories where the techs were sharp enough to spot fake pee, and there’s even a YouTube video of a lab assistant showing how. He mentions Quick Fix having a slightly greenish color, and it looks quite weird when put next to a sample of real urine.

Of course, this isn’t a sure thing. Most lab techs, especially if they’re only doing the cheap assessments, aren’t paid enough to care about checking samples that closely. If they haven’t shelled out for the big expensive tests, you should be fine.

But then there’s also the equipment. The labs get smarter and smarter every day, especially when the customer is willing to go for the premium tests, and all synthetic urine has some non-natural chemicals in it. It’s entirely possible that some labs may start checking for these chemicals to catch out fake pee.

So far there haven’t been any reports of Quick Fix running into such a test, but it’s still a possibility that you have to keep in mind. Thankfully Quick Fix regularly updates its formula to keep up with changes in the lab analysis, so if you’re worried that labs might figure you out, you’ll want to buy the most current version directly from the manufacturer.

Who Makes Quick Fix Synthetic Urine?

Quick Fix 6.3 is made by Spectrum Labs. Through the years, they’ve continually improved their product to make it as advanced as possible to stay one step ahead of the ever-improving current drug tests. They’ve made early formulations of Quick Fix urine, including versions like Quick Fix 4.0, 5.0, 5.7, 5.7-1, 6.0, 6.1, and now their latest version, 6.3.

For 25 years, Spectrum Labs and their Quick Fix pee line of products have ranked #1 when it comes to artificial urine with gleaming reviews and a steady stream (pun intended?) of returning customers.

How Do Urine Tests Work?

Urine tests and screenings can detect urine contents including any drugs in the presence of a person’s system. They’re quick, painless, and easy—and other than detecting drugs, they can also catch signs of infections, diseases, and diabetes.

Depending on what you are being tested for, some urine tests require that you give a sample of your first pee of the day and suggest that you catch the pee mid-stream. Others have no specifications and can ask you to pee in a cup right then and there.

Many workplaces require urine drug tests for new employees and existing employees. While there are other tests to screen for drugs (like hair tests), urine tests are the most cost-effective and practical.

The difference between urine drug tests (learn more) and hair drug tests is that urine tests are able to catch the presence of drugs in recent users, meaning if you’ve had cannabis anywhere from the past few months to the past few hours, it will detect the presence of CBD and THC. Hair tests, on the other hand, can screen for the presence of drug usage even years prior.technician testing fake urine

Where to Buy Quick Fix 6.3?

Quick Fix is available in most head shops, smoke shops, some vape shops, cannabis dispensaries, and adult novelty stores across America. If you’re not sure, ask them.

However, be warned, retail shops have been known to sell expired or even fake products. It sounds counterintuitive, but by default, you shouldn’t trust any synthetic urine you buy at a brick and mortar store.

If you purchase from the manufacturer directly, sometimes Spectrum Labs offers sales and discounts through their authorized dealers. One of their pretty infamous discounts to-date is their ‘buy three, get one free’ deal. That’s already a pretty sweet bargain, since you already need more than a 2 ounce bottle for a full urine cup test.

Plus, you can keep the rest handy for any random drug tests coming up later in the year. Pretty handy if you ask me.

FAQs About Using Quick Fix 6.3:

Q: If one bottle of Quick Fix isn’t enough and I don’t have time to buy another one, is it okay to mix it with water or another substance?

A: NO. Adding any foreign or extra substance to your sample of Quick Fix, whether liquid, powder form, solid form, etc, can compromise and alter the chemical structure. Each bottle is sampled and tested to ensure quality. By adding something else to it, you’ll risk contaminating your sample or even worse, you’ll risk your test results.

Q: Help! The test strip on my Quick Fix Urine bottle isn’t reading the temperature! Did I make my sample too hot?

A: Don’t panic! This typically happens, and it’s nothing to fret about. If your sample is indeed too hot, leave it at room temperature to cool down a bit and you should see the strip read a temp up to the green line. Once it’s cooled, you may reheat until you get a proper reading.

Make sure to heat in intervals of 10 seconds, meaning, heat it for 10 seconds, and check on the temperature reading before heating it again. An ideal temp reading would be 96 degrees F.

Q: I don’t have a microwave, and I tried to warm it up with my body temperature, but nothing’s worked. Can I leave it out in the sun?

A: Nope. Under no circumstance should you leave out your Quick Fix urine out in the sun.

Q: OKAY, so, what actually happens if a bottle of Quick Fix synthetic urine is under direct sunlight?

A: Depending on how long it’s been exposed to sunlight, it might be tricky to tell. There are no visual signs that can help tell if the sample has been compromised, but the urine itself may have already gone bad.

The UV rays from the sun can seriously alter and compromise the sample, as it affects the biochemical structure of Quick Fix. If you’re not sure how long it’s been in the sun, better to toss away the sample.

Q: Is fake pee illegal to purchase?

A: It is not, depending on the state or country, and given that the purchaser is of legal age. For most states in America, there is no telling as to what purpose its purchase is. Although it does cater and is used by a specific demographic, its purchase and possession is not at all illegal.

Q: I’m not living in the US but I need this! Does Quick Fix do international shipping?

A: Currently, Quick Fix only ships outside the US to Canada, Puerto Rico, and the United Kingdom. Items shipped to those countries are still subject to import customs, fees, and inspections. Quick Fix is not responsible for those fees.

Q: How much does Quick Fix cost?

A: Quick Fix synthetic urine prices start at $29.95 for a 2-ounce bottle. For a 3-ounce bottle of Quick Fix Plus, it will cost $39.95. Quick Fix also has value packs starting at $89.95 for a 3+1 pack of 2-ounce bottles and $119.95 for a 3+1 pack of 3-ounce bottles.
