Are Quick Fix plus synthetic urine reviews still accurate: can it pass a modern drug test? Also, Quick Fix synthetic urine has been around for many years and has passed drug tests. Quick Fix Plus is also available, but how is it different and what’s changed?
Whatever your situation, whether you are male or female, I’ve got you covered with every question and every detail you need to use Quick Fix pee or help you choose another synthetic urine product.
I’ll tell you how to use Quick Fix, what’s in it, whether it will fool a modern drug test, and answer that crucial question: does Quick Fix work?
How Complex Is Modern Drug Testing Really?
Quick Fix could still work is that modern drug testing isn’t as complex as you probably think.
- They do something called validity tests on your sample.
- They check the temperature, they look for common adulterants, and they look for the presence of two or three main chemicals found in urine.
- Beyond that, if they are suspicious they might physically look at it by holding up to the light or even sniff it, but usually that’s it.
So unless you fail a drug test and it receives more advanced chemical scrutiny, or there is extreme suspicion, then it doesn’t have to be that complex. But it has to be complex enough.

How Good Is Quick Fix Pee?
Look, having told you that, unfortunately, Quick Fix isn’t that good. It really only has the following characteristics:
- Looks like urine
- Contains urea and uric acid
- Contains creatinine
- Is within the correct specific gravity and pH ranges
But if they look for anything more than that then it’s going to be found out. And there is a strong chance that they could look for more than just one or two additional chemicals for better verification. The main reason people fail drug tests with synthetic urine is because they submit it outside the correct temperature range, which is between 90°F and 100°F.
Most cheap urine products rely on a heatpad to keep within that narrow temperature range. The bad news is that most fail to achieve this, including Quick Fix. It’s also important to note that if you are here wanting to learn about Quick Fix Plus synthetic urine, then you’ll be disappointed to know it’s exactly the same 6.4 formula as the standard Quick Fix.
The ‘plus’ product is simply a 3 fluid ounce product, rather than the 2 fluid ounces contained in the standard 6.4 Quick Fix product. You just get more urine in case you need to submit a sample larger than 2 fluid ounces (becoming more common).
Instructions
Let’s talk you through how to use Quick Fix, so you can see the steps you need to take:
- The urine is premixed, so simply shake it, loosen the lead, and put it in the microwave on full power for 15 seconds. Check the temperature strip after 30 seconds, and repeat the process until you get a good reading on the temperature strip.
- Activate the heatpad and stick it to the heated sample.
- Disguise the sample on your person. Remember, you won’t be intimately searched so you can simply tuck it into your underwear in your crotch area, and remember to wear baggy bottoms to disguise the fact.
- On arrival, check the temperature strip. You’ve got no options here other than hot or cold water, so take some with you, or plan to have access to it before you go into the building. This is a step people don’t talk to you about, and you may have to use it because the heatpad is such poor quality.

Does Quick Fix 6.4 Work Or Will It Fail Every Time?
Look, you might get lucky and Quick Fix will pass that drug test.
So does Quick Fix work? Yes, but if you only face the most basic validity checks nobody get suspicious. Any more chemical scrutiny though, or if somebody shakes it or sniffs it, and you are going to be caught out immediately.
There are far better products out there nowadays than Quick Fix pee kit. Don’t be fooled by the 6.3 formula, it can’t have been through many changes because the formula is so basic how would they change it?
So Quick Fix Reviews Are False?
So Quick Fix Plus synthetic urine reviews telling you it’s the best out there and will pass a drug test aren’t really being honest.
Reviews like this one, saying that it is very basic, but still could work, but there are significant problems in hurdles, are far more honest and realistic.
Overall, I’d only recommend you use Quick Fix Plus if you can’t get hold of anything else, you don’t really care about the drug test, or you simply can’t afford anything more than the $40 that Quick Fix Plus costs.
Avoid All Of These Low-Quality Synthetic Urine Budget Brands
It’s the same story with all of these low-quality budget brands of fake urine. Hell, they could even be made by the same company and then sold wholesale to be put in named boxes for all I know. They are all basic in composition, and none of them fulfills all of the criteria for standing a great chance of passing a modern drug test.
Plus, every single one relies on the awful cheap heatpads that are supposed to kick out a steady heat within a 10°F temperature range for several hours. It’s not possible, and it won’t happen.
Avoid all of these products:
- Magnum
- Urine Luck
- U Pass
- Monkey Whizz Range Synthetic Pee Kit
- Quick Fix
- Quick Fix Plus
- Synthetix5
That list isn’t exhaustive, but it covers most of them. You get the idea, if it’s cheap (less than $50) and is similar to any of the above, then you really must avoid it.
The Best Synthetic Urine Kit: Quick Luck
Having told you that those Quick Fix Plus synthetic urine reviews are wrong if they tell you it can pass a modern drug test, let’s look at what can pass one. You might not have heard of these products because they are only sold by the company that makes them. These are not farmed out at wholesale prices for maximum profit to anyone who wants to sell them.
Quick Luck is the newest and best of the bunch. Only sold by the company who make it, Clear Choice, it has the following characteristics:
- Highly complex – contains 14 chemicals found in urine
- Contains urea and uric acid
- Contains the right proportion of creatinine
- Is within the correct specific gravity and pH ranges
- Looks, froths, and even smells like urine
Not only will Quick Luck pass advanced chemical scrutiny during validity checks, and get around the curious employee who physically inspects it, but crucially, it doesn’t rely on a heatpad.
Instead, Quick Luck uses something called ‘heat activator powder’. The activator powder is pure genius because it’s undetectable when dissolved, and gently raises the heat of the sample when you put it in.
Simply tap in about one-quarter (obviously only if you don’t have a reading on the temperature strip and not it’s cold) and shake it gently until it’s dissolved. Repeat this process with small amounts until you get a good reading close to 100°F but not above that. You’ve then got about 15 minutes to submit your sample confidently. Tuck it back into your underwear against your skin and it could even be longer than that (but I’ve never had to wait that long).
As it’s an unsupervised test where you will be out of sight, you could even tap in a little more if it’s cooled during the submission process! The Quick Luck kit also contains a pair of thin and reliable heatpads. You probably won’t need them, but there’s no harm in strapping them to the sample and then using the heat activator powder as well.
Combined, its belt and braces security means that after you have got the temperature right, the heat pads will keep it within the correct temperature range for longer.

Best Alternative: Sub Solution Powdered Urine Kit
Sub Solution has been around for many years, and was the best on the market. It’s a formula and characteristics are far in excess of Quick Fix. Top of the synthetic urine reviews, it didn’t get as much publicity as some other brands because it’s only sold directly by Clear Choice.
It’s actually the original synthetic urine that Quick Luck was developed from.
The only real difference between Quick Luck and Sub Solution is that Quick Luck is premixed, whereas Sub Solution is a powder that has to be hydrated using jug-filtered water (one of those home jug filters in your fridge will do fine).
So Quick Luck is better for short-notice drug testing, and it’s the cutting-edge, most complex brand. You’ll pay a little more because of that. But Sub Solution nearly has all of the characteristics of Quick Luck, and apart from needing to be hydrated, will work just as well for any modern standard drug test.
Sub Solution also uses heat activator powder, which gives it an edge over any of the other products out there other than Quick Luck.

Quick Fix FAQs
Does Quick Fix Still work in 2024?
Synthetic urine reviews telling you that Quick Fix 6.3 works are not telling you the truth. Does Quick Fix work? Probably not, but you might get lucky. But Sub Solution and Quick Luck are far better options the modern drug testing.
Let’s finish up here with some Quick Fix and general synthetic urine FAQs.
Does Quick Fix Expire?
Synthetic urine has an expiry date printed on the box and usually the actual bottle of urine as well. However, you can also probably ignore that expiry date because they want you to buy more even if you haven’t used it.
As a general rule though, use it within one year of purchase if you really want to ensure it’s ready to go.
Can Quest Diagnostics Detect Quick Fix?
Quick Fix doesn’t contain biocide, a footprint that some big labs look for.
However, Quick Fix is basic and any validity checks by professional labs could spot it. In addition, Quick Fix doesn’t really look like urine held up to the light (slightly green) and doesn’t froth or smell like it, so a human investigating it will spot it instantly.
How To Use Quick Fix Without A Microwave?
You can use hot (not boiling) water to heat the sample up. Simply run it under tap until you get a reading on the temperature strip.
Alternatively, you can activate the heatpad, and as long as you keep it warm (tucking it into your underwear) then it should get up to temperature and stay there within one hour. However, the heatpad is notoriously unreliable.
Does Quick Fix Work For Urine Analysis?
Any thorough analysis of Quick Fix will expose it ruthlessly.mA basic validity check that only looks for urea, uric acid, creatinine, and a couple of other characteristics, will be passed. Anything above this will spot the fake.
How Long Is Quick Fix Good For After Opening?
After physically opening the bottle and letting air into the container, Quick Fix should be used within a few hours.nIt will start to deteriorate after that, even if you keep it in a refrigerator.
With any synthetic urine, you should only open it and expose it to air just prior to submitting it when you prepare it.
How To Keep Urine Warm For A Drug Test?
To reliably keep synthetic urine warm to pass a drug test you’ll need a good quality air-activated heatpad. Unfortunately, the heatpads with most synthetic urine products aren’t very good.
You could use hot and cold water to get the temperature right, but obviously you’d have to carry that or have access to it. The best option is to use heat activator powder, which gently raises the temperature and gives you complete control over the sample. This is only included with Sub Solution and Quick Luck.
Do they watch you pee for a pre employment drug test?
Nearly all drug tests conducted for pre-employment and during employment purposes are unsupervised. That means you’ll be behind a screen, and often in a completely different room, to submit your sample to the person conducting it.
Supervised drug testing is only really done under very specific circumstances, such as retesting after failure, or obvious avoidance tactics, and for things like law enforcement and probation purposes. The key thing to know is that they can’t just do an observed test on you without informing you in advance. For a standard pre-employment test it will be unsupervised, and you don’t have to worry.
How long does urine stay warm between your legs?
When you ask how long it will stay warm between your legs, I am assuming you mean outside the body!
Just the urine inside your underwear against your skin in the crotch area should keep it within a few degrees Fahrenheit of the correct temperature indefinitely. The problem is that it will not be quite warm enough. A good quality heatpad, designed to kick out the temperature at between 90°F and 100°F, will often work okay, but sometimes they fail.
The best option though is to use Quick Luck synthetic urine. It uses heat activator powder, which allows you to get the temperature completely accurate within one minute and not have to worry about keeping it warm.
How To Smuggle Synthetic Urine For A Drug Test?
The only drug test you could use fake urine for is an unsupervised one. All drug tests are unsupervised, meaning nobody will be in the room with you or observing you, unless you are told in advance.
These are easy to pass with synthetic urine, which is also easy to smuggle in. They can’t touch you intimately, so simply tuck the sample into your underwear and wear baggy bottoms so it can’t be spotted.
What Are The Best Synthetic Urine Brands?
The only products on the market right now which are complex enough to pass modern validity checks, and that use heat activator powder to give you granular control over the temperature, are Quick Luck and Sub Solution.
