5 Best Synthetic Urine Complete Kits In 2024 (Urinalysis)

Let’s face it:

If you don’t pass a drug test, you’ll be in trouble. And you pretty much know there is no way you’ll pass one with a bit of help. That’s why synthetic urine exists.

Well, not exactly.

Synthetic urine or ‘fake pee’ was created by laboratories to calibrate urinalysis equipment in the 1980s. It looks, smells, and, most importantly, tests exactly like normal drug-free human urine.

Today, fake pee is primarily used to effectively beat any urine drug test for any drugs.

That’s why everybody is looking for the best synthetic urine. Instead of you urinating in a cup (with drugs in the system, and hence in urine), pouring the best synthetic urine in that same cup has become the most popular way of how to pass a drug test with almost 100% guarantee.

Of course, there are good synthetic urine kits as there are bad ones; not all of them are as reliable as Sub-Solution, for example.

The thing about all synthetic urine is this:

You really have to be 100% sure that you have the best fake pee kit with you. There are no do-overs with drug testing; you only have one chance, and you have to get the right kit the 1st time.

Primarily, top-rated synthetic pee kits reliably pass two criteria that all drug testing labs test for:

  • Urine authenticity test. That means that synthetic urine has to be yellow, clear, with pH between 4 and 8, the right specific gravity, and at the right temperature. The best fake pee kits also nail down the 3 most important molecule concentrations in your urine; namely urea, uric acid, and creatinine.
    does synthetic urine work for passing a drug test with correct specific gravity appearance ph
    The best synthetic urine has to have the right color, appearance, specific gravity, pH, temperature, and contain just the right amount of urea, uric acid, and creatinine.
  • Absence of drugs. That means that synthetic urine is 100% drug-free and 100% biocide-free (cheap gas station fake pee kits may include biocides to prolong the shelf-life; those biocides may result in a failed drug test).

With the best synthetic urine under your belt or armpit, you don’t have to worry if you will pass a drug test. That’s pretty much guaranteed.

#1 Best Synthetic Urine Kit: Incognito Belt Premixed Fake Pee

incognito belt with synthetic urine for passing a drug test
Quality: 4.9 out of 5 stars
Reliability: 4.9 out of 5 stars
Type: Premixed
Heat Activator: No, Only Pads
Temperature Strip: Included (88-102°F)
Price: $$$$
Rating: 5 out of 5 stars

Of all the synthetic urine kits, Incognito Belt is by far the easiest to use. The belt contraption contains 3 oz of the best synthetic urine; the same solution found in the famous #2 Sub-Solution and #3 Quick Luck synthetic urine kits. Because the whole kit already comes with a convenient belt, the Incognito Belt is considered to be the best synthetic urine in 2021.

The Incognito Belt contains a premixed synthetic urine solution with exactly the right composition. Specific gravity, pH, color, appearance, urea content, uric acid content, and, most importantly, creatinine content match healthy drug-free urine as closely as humanly possible.

This is the only way to assure that will work 100% of the time. The other two are the right temperature and transportability.

Unfortunately, the Incognito Belt doesn’t include a heat activator and cannot be microwaved (the belt would burst). To heat it up, you have to use two heating pads that come included in the package. When the temperature is just right – 98-102°F – you keep it close to your, well, stomach to keep it warm.

The Incognito Belt is an all-in-one premixed synthetic urine and belt contraption. It’s the easiest to use because it already comes premixed; you only heat it up, strap on the belt, and you have the whole thing hidden under your shirt:

  • All-in-one synthetic urine + incognito belt
  • Contains the best synthetic urine formula; with the most precise urea, uric acid, and creatinine content
  • Easiest to use; it already comes premixed, just heat it up and strap the belt under your shirt
  • When used correctly, it will work every time
  • Doesn’t include heat activator; you have to use pads only
  • Higher price because it’s not just synthetic urine, it’s the all-in-one product with belt

#2 Best Synthetic Urine Of 2018, 2019, And 2020: The Famous “Sub-Solution”

best fake pee with heat activator on the market
Quality: 4.8 out of 5 stars
Reliability: 4.7 out of 5 stars
Type: You Mix It Yourself
Heat Activator: Included
Temperature Strip: Included (88-102°F)
Price: $$$$
Rating: 4.7 out of 5 stars

The Sub-Solution is the best synthetic urine for the past couple of years. This is because of a simple fact: it contains an unbeatable synthetic urine solution. Coupled that with the patented heat activator containing lithium chloride (LiCl) and you have yourself a top fake pee to pass any drug test with.

(The #1 Incognito Belt is only better because it has all the transportation to the lab taken care of with the included belt)

Sub-Solution is made by Clear Choice. It’s on the market for 20+ years now and has the best track record of any synthetic urine kit. The reason why Sub-Solution is unbeatable is that the synthetic pee formula is updated every year to adjust to the new laboratory urinalysis standards. That helps keep the Sub-Solution undetectable on any and all drug tests.

When you buy it, you have to mix it; you add the powdered synthetic urine in the vial to the included flask and add water. Then you have the patented heat activator which you use to raise the temperature of the whole solution. The 88-102°F temperature strip on the flask will turn green when you’re at the right body temperature; you can maintain that temperature right up to the lab drug test by hiding it close to your body.

All in all, the famous Sub-Solution has been on the market for 20+ years and it’s pretty much unbeatable and 100% biocide-free. That’s because the formula is continuously being updated to meet the urinalysis standards. It’s also available for a reasonable price:

  • Best synthetic urine in 2018, 2019, and 2020
  • On the market for 20+ years with unbeatable track-record
  • Best and most readily updated solution formula; this is the most authentic 100% drug-free fake pee
  • Includes patented LiCl heat activator that helps you heat it up
  • Reasonable price for such an excellent formula
  • It doesn’t come premixed: you have to mix it yourself, according to the instructions
  • Unlike Incognito Belt, it doesn’t include a carrying contraption; you have to put it in your pants, under armpits, and so forth

#3 Top-Rated Synthetic Urine With Foolproof ‘Heat It Up’ Method: Quick Luck Fake Pee

Quality: 4.9 out of 5 stars
Reliability: 4.9 out of 5 stars
Type: Premixed
Heat Activator: Included + 2 Pads
Temperature Strip: Included (88-10°F)
Price: $$$$
Rating: 5 out of 5 stars

Quick Luck is basically an upgrade to the famous #2 Sub-Solution. It does solve two problems the Sub-Solution kind of does have: not being premixed, and how to keep the temperature near the body temperature when heading to the drug testing facility. It does come at an additional cost of about $20 above the Sub-Solution price.

But let’s be clear: Quick Luck is only so good because it contains the best synthetic urine formula; the same one as #1 Incognito Belt and #2 Sub-Solution. That is the continuously upgraded formula that has been used to pass drug tests for 20+ years now.

The added value of Quick Luck over Sub-Solution is that it comes premixed. You don’t have to follow the how-to-mix it instruction; the 3 oz plastic bottle is already filled with the best synthetic pee.

Quick Luck is also the easiest one to heat up (with a heat activator) and to keep at that body temperature (with heating pads). Both heat activator and 2 heating pads come included in the package. You also get detailed instructions that include tips and tricks like this ‘Heating Options’ leaflet:

instructions how to heat up synthetic urine to body temperature

In short, the Quick Luck is just an upgraded version of Sub-Solution that is premixed and has heating pads. Being more convenient to use does cost about $20 more:

  • Upgraded version of Sub-Solution
  • Includes 2 heating pads to keep the synthetic urine temperature constant before the drug test
  • It comes premixed; you don’t have to mix it yourself
  • The formula of the solution is the tried-and-tested formula that has been unbeatable for 20+ years
  • It is more expensive than Sub-Solution
  • You have to hide it under your clothing; doesn’t come with a belt or stash pants

#4 Cheapest Synthetic Pee Kit (That’s Still OK): Quick Fix 6.3

Quality: 3 out of 5 stars
Reliability: 2.5 out of 5 stars

Price: $$$$

You have probably noticed those $30 synthetic urine kits in the gas stations. They have wild colors, X’s, Dr’s, and they look pretty much toxic. In most cases, those are very risky bets if you want to reliably pass a drug test. Of all these cheap synthetic urine kits, however, one is a bit better than all the rest, and that’s Quick Fix.

Quick Fix is actually one of the most well-known synthetic urine kits because it’s both cheap and a bunch of people has used it to pass a drug test; not all, mind you.

The thing with synthetic urine is that you really need reliability, and reliability costs. Quick Fix has some problems in the past; we have come from 6.0, 6.1, 6.2, and now to Quick Fix 6.3 version. It safe to say that it’s not 100% reliable, and when it comes to drug testing, you really need something like #1 Incognito Belt, #2 Sub Solution, or #3 Quick Luck to be 100% sure you have the best chances of passing.

Still, if you want to save a buck and risk it a bit, Quick Fix 6.3 is a calculated risk, and it’s available for a lower price:

  • Cheapest synthetic urine that’s pretty OK
  • You do get 1 heat pad to heat it up
  • Isn’t 100% reliable
  • Doesn’t include a heat activator
  • Doesn’t include a belt
  • Doesn’t have a perfect track record over the years

#5 Best Powdered Human Urine Kit By TestClear: Synthetic Urine Alternative

Type: You Have To Mix It Yourself

Price: $$$$
Rating: 3.4 out of 5 stars

TestClear has made something that is not synthetic urine at all. While most fake pee producers try to nail the urine formula as exactly as possible, TestClear took that out of the equation and made a kit that is an alternative to synthetic urine.

They took actually 100% drug-free human urine and dehydrated it. That’s pretty much it. This is the powdered real human urine. The only thing you have to do before the test is rehydrating it by simply adding water and mixing it.

All the physicochemical properties like pH, specific gravity, appearance, and even urine smell are on point. A powdered human urine kit basically serves as a substation of urine; it’s just that you don’t get hot pee from a friend (that starts smelling in about an hour), you get a dehydrated version and rehydrate it yourself before taking a drug test.

The real con of a powdered human urine kit is that you have to way to heat it up. You’re actually forced to resort to microwave and close-to-body heating which is not ideal at all.

All in all, the powdered real human idea is actually quite a brilliant idea and the kit itself can be considered a worthy synthetic pee alternative. It’s also available at a lower price than the best synthetic urine kits:

  • Actual human 100% drug-free urine that has been dehydrated
  • Contains not only 11 essential urine compounds like urea, uric acid, and creatinine, but the whole range
  • It’s not all that easy to rehydrate it, and the urine starts to smell really quickly
  • You can no way to heat it up; no heat activator or heating pads
  • Might contain the whole range of chemicals found in urine but it’s overkill; labs only measure a very limited range

Rounding It Up

It’s safe to say that any drug test can be beaten by using a reliable synthetic urine kit. Having a foolproof synthetic urine formula is essential; that’s the only way to ensure synthetic urine will be undetected and will pass a drug test with flying colors.

What is more, the kits provide you with a way of how to increase the temperature of synthetic urine, either via heat activator, heating pads, or both.

#1 Incognito Belt with the best premixed synthetic urine adds the convenience of the belt that you can just strap on yourself. That alone makes it the best all-in-one synthetic urine kit in 2024.
