Sub Solution Review: The Best Fake Urine You Can Buy?

If you’re looking to use fake urine to pass a drug test then Sub Solution is a brand name you’re going to come across pretty fast. In this Sub Solution review, we’re going to answer that key question around is it the best fake urine money can buy?

You’ll learn what the characteristics of good synthetic urine are, and how close to the ideal Sub Solution comes. You’ll get full instructions on using Sub Solution properly, and we will talk about what makes Sub Solution so much better than almost every other fake urine brand out there.

As well as all that, we will conclude this review by not only telling you where to buy Sub Solution at the best price, but also tell you about something that could be even better, and another product that can increase your chances of passing a drug test to use alongside Sub Solution.

How Do You Know If Fake Urine Will Pass A Drug Test?

To pass a modern urine sample drug test your fake sample has to be incredibly close to real human urine in all its characteristics.

Just a few years back, it was good enough for fake urine to “sort of” look like the real thing and to contain only your urea, uric acid, and creatinine. Especially for basic pre-employment drug testing (the cheap unsupervised five-panel drug tests most people face), most brands of fake urine would do.

But things have moved on, not only has drug testing become digitalized and more professional, but there’s the modern Internet. Drug companies use it just like us, and they can research how people are trying to get around drug tests, on top of tapping into the increasing body of research into analyzing drugs in urine.

So what I’m saying here, is that you need the most complex formula possible. But, more than that, it has to be submitted within the right temperature range.

About Clear Choice Sub Solution

As you can see from what I said above, that’s one hell of a lot of things that have to be covered for a fake sample to pass as valid. Clear Choice Sub Solution has been the #1 selling brand for several years now, overtaking Quick Fix for several key reasons.

These are the characteristics of Sub Solution that make it so popular:

  • Contains uric and uric acid
  • Sub Solution contains creatinine in the correct quantity
  • Sub Solution contains a total of 14 chemical markers found in human urine
  • Sub Solution is perfectly balanced for pH and specific gravity
  • Sub Solution doesn’t rely on the variability of a heatpad to keep its temperature correct

The only downside to Clear Choice Sub Solution is that it’s a powder rather than premixed urine. So you will need access to some filtered water to use it. That makes Sub Solution unsuitable for on-the-job drug testing where you haven’t got access to a water source.

Sub Solution Instructions

My last drug test was in January. I used Sub Solution and passed. It was an on the job drug test, but they are always scheduled with 24 hours’ notice. That made it perfect for Sub Solution and as usual, it did the job.

These are the Sub Solution instructions you need to follow to pass a drug test:

  1. Fill the supplied plastic container up to the fill level with lukewarm filtered water.
  2. Gently add the contents of the powdered synthetic urine vial to the water. Gently shake the bottle until it’s completely dissolved and clear. This takes a couple of minutes.
  3. Check the temperature strip on the side of the sample container. If the water is warm enough you may get a reading. The temperature needs to be between 90°F and 100°F. Human urine exits the body at between 96°F and 100°F. But legally, to allow for up to 4 minutes of cooling, any sample of 90°F and above has to be accepted. So you’re looking to get the temperature as close to 100°F as possible, without going over.
  4. If there’s no reading, and you know the temperature is not hotter than 100°F (because there will not be reading if it was hotter), add about one-quarter of the heat activator powder. Gently shake it until it’s dissolved and then watch the temperature strip. If it doesn’t register, repeat the process with a little more powder until you get a reading.

As you can see, Sub Solution instructions are pretty straightforward. However, this is the crucial point a lot of people miss.

With standard urine, you get a heatpad. That means you have to prepare the sample before you leave to submit your drug test, which could be an hour or more before your appointment time. So you prepare the sample as above, but instead of using the heat activator powder to raise the temperature, using a microwave and then maintaining the temperature while you travel to the testing facility with the heatpad.

However, the beauty of Sub Solution is in that heat activator powder. You don’t even need to heat the sample up before you leave. Just turn the sample into a liquid, and then tuck it in your underpants close to your skin in your crotch area. Not only will this allow you to submit it without it being noticed, but it will also get the temperature closer to the required level without a heat source.

Then when you arrive, before you go into the building, you can then use the heat activator powder. And, because it’s going to be unsupervised (you’ll be behind a screen or in a different room to the person administering the test when you submit the sample), you can check the temperature and raise it if needed right there before you pour it into the sample container.


What Makes Sub Solution So Good?

The conclusion of this Sub Solution review, before I move on to giving you more vital information around the synthetic urine you choose, is that it’s thoroughly recommended.

I’ve to pass drug tests with it, and I know plenty of other people who have as well, and the online feedback is superb as well.

Sub Solution is good for the following key reasons:

  1. Sub Solution doesn’t rely on a heatpad. These can fail, and submitting a sample outside the correct temperature range for human urine is the number one reason why people fail with fake samples. The heat activator powder takes that worry away completely.
  2. Sub Solution is high-quality in terms of its composition and mimicking human urine. It’s complex enough to pass any level of scrutiny.
  3. Sub Solution is one of the few brands of fake urine that doesn’t contain biocide. In 2018 a rumor started to circulate that the big testing labs had realized that most brands of fake urine contained an artificial preservative called biocide to lengthen the shelf life. A spike in failures amongst a lot of brands suggested that all they were doing during the initial validity checks was testing for the presence of biocide, which could rule out 90% of fake samples.

Sub Solution Vs Quick Fix

When it comes to Sub Solution Vs Quick Fix, there’s really no comparison in terms of the quality and ease-of-use.

Quick Fix is good enough to pass a basic pre-employment drug test. It contains the basics in the chemicals, and it uses a pretty reliable heatpad. It’s also dirt cheap, costing $30, compared to the $80 you’ll pay for Sub Solution.

However, when it comes to composition and characteristics, Sub Solution is so much closer to human urine, and if you’ve got the money you really wouldn’t want to risk using Quick Fix instead.

Also, you’ve got that battle between the heat activator powder and using a heatpad, which the heat activator powder wins hands down both in terms of granular control over the temperature, and the fact you can raise the temperature right there when you submit your sample.

Is Sub Solution The Best Synthetic Urine Product?

Having raved about Sub Solution, there is now a better fake urine product out there. It’s another Clear Choice urine product. It’s basically the big brother of Sub Solution. It’s called Quick Luck. Sub Solution is updated every year, but Quick Luck is a newer and slightly more complex formula that’s also updated every year.

Quick Luck uses heat activator powder as well, and even contains a pair of high-quality heatpads should you want to transport it at the correct temperature.

Also, Quick Luck is premixed. That makes it perfect for on-the-job drug testing. You can keep it in your cab, in your car, or in your locker. With just two minutes’ notice, you can tap in the heat activator powder until you get it within the right temperature range, and you have a valid sample.

Where To Buy Clear Choice Urine

Sub Solution costs $80. The only downside to it is the fact that you need to mix it with filtered water. It’s a small inconvenience, but it’s an extra step in comparison to Quick Luck.

Quick Luck costs $100 and is the ultimate fake urine kit you will get your hands on now. But for me, I’ll stick with Sub Solution because I will not face on the spot drug testing, and I already have a box ready for my next scheduled test.

When you buy Quick Luck or Sub Solution, I’d like to refer you to another product Clear Choice urine sell, called “the practice kit”.

The practice kit contains heatpads and heat activator powder. It also contains the mixing bottles, but not the fake urine. So you can use warm water to practice raising and maintaining the temperature. That will allow you to understand exactly how Sub Solution or Quick Luck work, meaning when you do face a drug test you can prepare the sample quickly and competently.

Best Synthetic Urine Kits & How To Use Them

If you’re a regular weed smoker or drug user, then facing a drug test is your worst nightmare. If you can get yourself a high-quality synthetic urine kit though, then all those worries vanish.

It really is a problem because lets be honest, even though weed is legal in a lot of states now, that doesn’t mean you can turn up for a drug test and fail but still get employed. That’s not quite how things work. It’s ridiculous, so you have to protect yourself. That’s what I’ve learned to do now.

What I’m going to do here is talk you through what’s in the best synthetic urine. How it looks, what’s in it, basically the characteristics it needs to have to pass scrutiny.

I will also warn you away from the poor quality brands, give you full instructions based on my own experiences, and finish up with a detailed fake urine review of each of the top four brands based on the criteria I’m going to outline to you first.

How Realistic Is Passing A Drug Test With Fake Urine

Although it may actually seem like a crazy idea on the surface, fake urine is really the best way you have a passing a drug test. As long as the quality is high, and it submitted within the correct temperature range, it should be good enough to pass most levels of drug test.

Look at it this way, if you are a heavy weed smoker and you are one week from a drug test, or you think you could face one after an interview or something, these are your options:

  1. You do a natural detox. That means abstaining, it means living healthily, it means exercising. You drink tons of water, and you try and push out as many toxins as possible. You can accelerate this using high-quality detox pills like Toxin Rid, which can half the amount of time it takes, but if you’re a daily weed smoker it’s still going to take at least a week, often longer, to get totally clean via this route.
  2. You could just mask the toxins for a few hours using a high-quality detox drink like Rescue Cleanse or Ultra Eliminex. It’s beautifully convenient, but if you’re a chronic weed smoker or drug user, then you could only get a couple of hours toxin free before fresh metabolites from the drugs appear in your urine. If there is a delay, if it takes you a while to submit your sample, you’re playing with fire.
  3. That leaves fake urine kits. As long as you select the best synthetic urine possible, and you make sure it’s submitted within the correct temperature range then you really do stand up to a 95% chance of passing. For me, if you’re a regular smoker or user and you don’t want to detox (or you don’t have time), and you are concerned about the unknown amount of time you’d have clean using a detox drink to mask the toxins, then the only realistic choice is fake urine.

What Are The Characteristics Of The Best Synthetic Urine?

If you’re seriously going to use a synthetic urine kit to pass a drug test though then you have to buy the best quality one available that will get the job done.

Just like cars, there is a myriad of fake urine products out there all with their own strengths, weaknesses, and price tags.

But let’s look at the crucial characteristics that the best synthetic urine has to have as a minimum to really pass close scrutiny:

  1. Firstly, it has to be complex in the formula. So it should contain at least creatinine, urea, and uric acid. But really, it should contain many more chemicals and waste products found in the urine in order to stand the best chance of facing the toughest validity testing.
  2. It has to be balanced for both pH and specific gravity. This is not easy to achieve, and only the best fake urine brands out there achieve it.
  3. It has to look and froth like urine as much as possible. If it can smell like it even better. I know that sounds crazy, but I have seen online a lab technician mentioning that sometimes they do actually sniff the sample. I’m guessing it’s a quick way of seeing if a suspicious sample needs more scrutiny. I wouldn’t have thought it’s common, otherwise, a lot of the cheaper brands would not be passing basic pre-employment drug tests.
  4. Good quality synthetic urine also has to have a reliable heat maintenance source. Whether it’s a heatpad or heat activator powder, it has to have the ability to keep your sample within the narrow temperature range of between 90°F and 100°F (the legal temperature between which urine samples have to be submitted), or the heat activator powder has to be able to heat the sample up rapidly just before you submit it.

Once you put all that together, there’s not a lot of choices left on the market. But don’t worry, at the end of this I’m going to give you a fake urine review of each of the top four brands out there that do tick all the boxes I’ve just mentioned.

Which Synthetic Urine Kits Contain Biocide?

Biocide is a problem in the fake urine marketplace. It wasn’t until a couple of years ago, then suddenly fake urine started failing in much higher quantities.

People online put their heads together, and it became obvious that something was happening. There was something in common between the brands that were failing. Some people just thought it was to do with quality, but even a couple of the previously reliable brands just started failing people.

People realized that it was because of something called biocide. That’s an artificial preservative found in lots of everyday products.

It became obvious that it was a “footprint”, something in common between all the different types of urine. By testing for its presence, the labs could basically rule out most fake samples without any further checks. It was basically game over.

However, a few brands didn’t contain biocide, or removed it and replaced it with another preservative that is still not being looked for. Those are the synthetic urine kits you need to be using.

Where To Buy Fake Urine For A Drug Test?

If you’re wondering about stores that sell synthetic urine, then I’d ask you to step away from that idea pretty quickly.

The only places locally are going to be smoke shops and independent retailers. They tend to stock the worst quality fake urine brands at the highest prices.

It’s the same online as well. Steer clear of online marketplaces like Amazon and eBay, you’ll get fakes, you’ll get out of date products, and you’ll get fake urine that’s been heated up and then not used.

For me, the best place to buy synthetic urine is online from specialist retailers. All you have to do is get your order in a couple of weeks before you could face a drug test and you will never be caught out.

Steer Clear Of The Following Brands

Having warned you away from stores that sell synthetic urine, let’s now tell you about brands of fake urine that definitely aren’t the best.

Magnum, Xstream, U Pass, Synthetix5, Jet Clean, Agent X. These are all brands that are widely sold locally but are awful.

Don’t buy them online either. These are the brands that started failing a couple of years ago, and they also aren’t great in the formula quality either. Why take the risk when they cost nearly as much as the top four synthetic urine brands I’m going to talk you through in a moment anyway?

How To Use A Synthetic Urine Kit

Before I do detailed fake urine kit reviews, I want to give you some brief instructions on making sure you pass a drug test with fake urine. These are the instructions that I have used to successfully pass.

  1. If you’re using a heatpad activate it before you warm the sample. If you’re using heat activator powder, you don’t have to worry about that.
  2. The second step is to mix it up with some filtered water if it’s a powder. If you’ve bought premixed urine, you don’t have to worry about this.
  3. If you’re using a heatpad you’ll then have to warm the sample up to take the stress off the heatpad so it lasts a few hours. Use a microwave, and gently microwave it for about 15 seconds. Check the temperature strip; you want it to be between 90°F and 100°F. It hasn’t registered, give it another short burst until it’s close to 100°F without being above it.
  4. Whether you have to warm the sample because you using a heatpad, or if you don’t have to bother because you using heat activator powder, the next step is the same. Tuck the sample container in between two pairs of underwear. This will keep it secure (even though you will NOT be searched or scrutinized because you’ll be facing an unsupervised drug test) and it will keep it closer to body temperature.
  5. When you arrive at the place you’re going to submit your sample if you’re using a heatpad then check the temperature. If it’s not warm enough you’ll have to find a way of warming up. Hot water from a flask is brilliant for this. If you using heat activator powder, now is the time to tap some in and raise the temperature by agitating it. If it doesn’t register with about one-third of the powder, tap in a little bit more at a time until it does. Give it about one minute between adding powder.


Synthetic Urine Review: Top Four Brands

Hopefully, you now understand how to use a synthetic urine kit successfully.

My advice is to go for the brands that use heat activator powder though. The ones that have heatpads are more hassle, but on the flip side, they are usually far cheaper. If money is a problem, go with the cheap brands, if it’s not, I’d go with choices one and two from the fake urine reviews below.

1. Clear Choice Quick Luck Synthetic Urine

This product from Clear Choice has only been out for about 18 months but it is definitely the premier synthetic urine kit on the market now.

It’s the most complex formula with at least 14 chemicals found in real urine. It’s going to pass almost any level of drug test, almost any level of scrutiny.

Quick Luck also looks, smells, and even froths like human urine. It’s going to pass the sniff test if it’s done, it’s going to pass any visual scrutiny.

It’s also premixed. Alongside the fact that he uses heat activator powder which can heat the sample in about one minute, that makes Quick Luck perfect for on the job drug testing. You also get a pair of high-quality heatpads with Quick Luck, but I’m not sure you would ever use them. But it does give you the additional option to transport a pre-heated sample should you want to.

Keep it in your cab, in your car, in your locker at work. Just tap in some heat activator powder, shake it up, get the temperature right in about two minutes, and you have a viable sample.

On the downside, Quick Luck costs $100. But you are paying for premium quality fake urine that won’t let you down. Quality costs, but if you got the money this is what I would bio.

2. Sub Solution

Also from Clear Choice is Sub Solution. It’s still the number one selling brand and has been for a couple of years, but it isn’t quite as complex as Quick Luck.

It contains 14 chemicals found in urine though and is going to pass the same level of scrutiny as Quick Luck.

The only real downside to Sub Solution, when stacked up against Quick Luck, is the fact it’s a powder rather than a premixed liquid. That means it’s not suitable for on the spot, or really rapid response, sample submission.

It does use heat activator powder like Quick Luck though, and alongside the complexity, as long as you’ve got an hour to prepare the sample with some filtered water, it’s good enough to pass any level of scrutiny.

Sub Solution is slightly less expensive than Quick Luck though, costing $80. Still a premium price, but you’re getting an incredibly high-quality fake urine that will pass pretty much any drug test, as long as it submitted within the correct temperature range.

3. Quick Fix Plus Synthetic urine

Third, on my list of the best synthetic urine kits is Quick Fix. This is nowhere near as good as Quick Luck or Sub Solution in terms of quality, but it is good enough for a basic pre-employment drug test.

Even the large 3 ounce Quick Fix plus size only costs $40, and the smaller to fluid ounce size costs just $30.

It’s a more basic formula, containing just creatinine, uric acid, and urea. But that’s all they are probably going to look for in a basic five panel drug test.

It looks pretty good but isn’t quite as convincing in terms of its physical characteristics as Sub Solution and Quick Luck.

It has a pretty reliable heatpad, but having a heatpad at all does raise the chances of failure ever so slightly, and you don’t get that granular control over the sample temperature as you do with heat activator powder.

But Quick Fix is available locally, and whether you buy online or offline, if you don’t care about the drug test that much, or you know it’s definitely going to be a basic one, it’s good enough.


  1. Monkey Whizz

Fourth on my list of the top synthetic urine kit options out, there is Monkey Whizz.

It’s for only because something had to be between Quick Fix and Monkey Whizz. Both are very similar, costing around $30, and having the same sort of complexity and look.

Both Monkey Whizz and Quick Fix use a heatpad, and it’s a pretty good one. There’s not much to choose between them there either.

The only thing I will explain to you is that Monkey Whizz is actually the name of an incognito belt product. It contains premixed synthetic urine, and you dispense the urine through a tap into the sample container. It’s meant for standing in the natural position, but I don’t see how you get away with it in a supervised drug test. So to me, it’s a pointless gimmick.

The Monkey Flask product though is exactly the same as Quick Fix generally and contains exactly the same fake urine as you get in the Monkey Whizz product. It costs $30, and is basically a flask of premixed urine with a heatpad.

Toss a coin, and go for Quick Fix and Monkey Whizz. For me, they both have a basic formula, but they definitely also both have the ability to pass simple pre-employment drug tests.

However, if you want the best synthetic urine going, get Sub Solution. If you want urine it’s as good as Sub Solution but is also already hydrated, and with heatpads added in as an option, then pay the extra $20 and get Quick Luck instead.
