Sub Solution is a powder that is designed to help you pass a urine drug test. The kit comes with everything you need to make your own synthetic urine, which is undetectable and free of toxins. All you need to do is add water and the synthetic urine powder to the mixing container, then activate the heat activator. This will cause the mixture to reach the correct temperature, which you can then measure with the temperature strip.

Just $85 gets you the Sub Solution kit, which includes the powdered synthetic urine container, heat activator, mixing container, temperature strip, and 5 stars rating. This premium Clear Choice product has been helping people pass urine drug tests for quite some time now.

The product also has considerable positive customer testimonies, with one review that says, “Well, to start, I went over numerous different products and had a quick fix but decided to go with this as saying it’s the best on almost every review I went on. The directions were very easy and went smoothly with the mixing and heating process.

Once I submitted my test on a Thursday, I was freaking out and nonstop, worried if this would really work. Monday came, and I got a call all clear and the start date for the new job. Would go with this product if needed in the future, and now from experience not be concerned at all. Thank you, sub solution!!!!”

Incognito Belt

Incognito Belt is a premium premixed synthetic urine solution that contains uric acid. It has a bladder bag with 3.5oz of urine solution and provides two uses. Two heat pads are included that act as heat activators, and a temperature strip is included for accuracy. The company claims that its product will help you test negative and pass a urine drug test with flying colors.

A happy client’s review about Incognito Belt says, “Relax. It works all about the temperature. I saw most people place their heater 1 hr before the test; I placed and wore mine 2 hours prior to being sure. Held it under my waistline. The temperature got to 102 F while waiting in my car. Flipped it outside my belly, and it cooled with no problem. 90-100 f will pass.

The tester made me take my hoodie off, nothing more. Have me the standard 4 minutes, which is more than enough time to sweetie this into a cup. Worked like a charm. Got my best job ever. Will buy it again if necessary, absolutely.”

The product also offers detailed instructions on how to use its product, as well as how to store it properly. Incognito Belt has received 163 customer reviews and has an overall rating of 5 stars out of 5.

Quick Luck Premium Synthetic Urine Kit

The Quick Luck Premium Synthetic Urine Kit comes with already mixed synthetic urine solution, two heat pads, and a heat activator powder. It is formulated to help those who fear being tested positive for drugs.

The kit also comes with the option to include a Stash Leg Belt, THC Test Panel, Five Panel Test, and a Practice Kit, which allows you to utilize the kit comfortably. While the Quick Luck kit is effective at just $100, it should be noted that extra charges may apply if you wish to purchase additional items.

Sneakpass’ Quick Luck review reads, “Wow. The only word to describe the product. Absolutely flawless. As long as the temperature is good, there is nothing to worry about! My sample was sent to one of the leading labs in the country and was not detected.

I used two store-bought hand warmers to get the bottle up to temperature and taped one store-bought handle to the bottle to maintain the temp. I was nervous about using the heat activator, knowing my sample was going to a prestigious testing company. At the time of the test, my sample was 96-97 degrees and passed with flying colors. Highly recommend it if you’re seriously stressing like I was.”

The Practice Kit

The Practice Kit comes with everything you need to practice using synthetic urine, including a temperature strip, heat activator, and the right setting for just $65.

Using the Practice Kit samples, you can learn how to use the temperature strip and heat activator and get the right setting without worrying about wasting synthetic urine. Plus, the Practice Kit is reusable for up to 2 uses, so you can keep practicing and mixing until you perfect your technique.

Urine Additive

Urine Additive

Spike Additive

Spike Additive is the smallest and most powerful urine purifier available. It is undetectable and comes in 2 vials. You need to pour the entire content into your urine to avoid being tested positive.

Spike Additive was developed after years of intensive lab research and clinical tests. The guaranteed effectiveness makes it a popular choice among those who want to avoid being tested positive for drugs.

A Spike Additive review states, “This actually works if you have the test that has the temperature strips. It will not work if you have a lab test. But make sure you pour in the vial before you urinate into the cup. The vial will absorb into the strips and cause all the lines to appear; after you wait about 15 seconds, then urinate in the cup, and you will have passed before u even deposit urine into it.

But if you pee into the cup and then add the spike additive last, you will fail immediately. So make sure you pour in the vial FIRST! Great product, absolutely amazing.”

Oral Clear Gum is the world’s best saliva-neutralizing solution, backed by scientific research. It has undergone multiple clinical tests, and the evidence is clear – it works! Simply consume 1 hour before getting tested for toxins or drugs, and you should be in the clear.

So if you’re worried about failing a drug test, don’t be – make sure to chew some Oral Clear Gum beforehand. It’s the surefire way to pass immediately.

One customer’s rave review claims, “Oral Clear wins again. I have used this gum 3 times for employment screens. I’m an everyday smoker; I vape and dab as well. I’m lucky enough to know when I’m being tested, so I abstain for 2 days and brush the hell out of my mouth and teeth for those 2 days. I always pass.

The price is high but it’s worth it. Instructions state that abstinence isn’t necessary, so I bet it’d work in a police stop as well. I plan on ordering more just to have.”

How Do Drug Tests Detect THC?

Drug tests are used to assess if an individual has been using drugs such as marijuana, cocaine, and amphetamines, among others. THC (tetrahydrocannabinol), a psychotropic component of cannabis plants, is one of the substances detected by these drug tests. So how do they detect it?

The most common form of drug testing is urine testing, wherein test samples are collected and analyzed in a laboratory. In urine testing methods for detecting THC, an initial screening is done utilizing an Immunoassay (IA) antibody-based technique. This method uses antibodies that specifically bind with marijuana metabolites which are then detected by fluorescent or photometric means.

If this initial screen yields positive results for THC metabolites, then other more sensitive detection methods, such as mass spectrometry or gas chromatography/mass spectrometry (GC/MS), are used to verify the results.

Another type of drug testing method used is blood testing. Blood samples are taken from individuals being tested and tested using the same antibody-based IA technique as with urine samples.

However, if there’s a need for confirmation, then different technologies such as liquid chromatography and GC/MS may be employed instead of just mass spectrometry, like in urine analysis.

The reason why instruments like LC and GC/MS are used instead of just MS is that blood sample concentrations tend to be lower than those observed for urine samples and thus require more sophisticated techniques for detection.

Last but not least, hair follicle testing is becoming more and more popular because it offers very quick findings and, depending on the length of hair being assessed, can identify drug usage up to 90 days before the sample was obtained.

Although hair follicle analysis similarly employs GC/MS, it incorporates extra methods known as derivatization reactions into its protocols, which improves detection sensitivity in comparison to the standard immunoassays used in urine and saliva testing.


What Is Synthetic Urine?

The term “synthetic urine” refers to a solution that imitates real human urine. It is usually composed of water, urea, and creatinine. Synthetic urine is often used in serial testing, which means that it can help you test negative for drugs even if you have recently used them.

While synthetic urine is not intended for human consumption, it is safe to use for drug testing purposes. In fact, many people prefer to use synthetic urine because it eliminates the risk of exposure to infectious diseases that can be transmitted through bodily fluids.

Are Synthetic Urine Products Undetectable?

Synthetic urine products are designed to simulate the appearance, chemical composition, and behavior of real human urine. These products typically contain urea, uric acid, creatinine, and other compounds found in human urine.

While some synthetic urine products may be undetectable by visual inspection, most will be detected by laboratory testing. The presence of synthetic urine in a sample may lead to a false positive result for the presence of proteinuria or other abnormalities.

Can Urine Tests Detect THC After 7 Days Of Consumption?

The short answer is, “it depends.” Urine tests do not necessarily need seven days to detect THC after consumption since the amount that can be detected varies depending on usage and metabolism rates.

Typically, the most common type of urine test used to check for drug abuse is known as an immunoassay test. These tests are designed to identify THC metabolites in the body and are most effective within three to five days after the last use. Some more sensitive versions can pick up even trace amounts up to two weeks afterward.

For occasional users, it usually takes anywhere from three to four days before their system has cleared the majority of the molecules. Habitual users may leave THC molecules in their system even longer than seven days.

Some estimates suggest it could take up to 30 days or more for their systems to completely clear out all traces of these molecules due to their higher levels of tetrahydrocannabinol (THC).

What Is Synthetic Urine Often Made Of?

To start, synthetic urine contains ingredients like uric acid, creatinine, potassium, chloride, and phosphate ions in concentrations that accurately mirror human pee. It also carries other constituents like urea and nitrogen waste products that come through with regular sweat production.

While the exact makeup of specific brands varies slightly, most feature a key set of elements within similar range tolerances.

Though artificial urine is predominantly considered a drug testing agent, it’s also employed by laboratories to conduct certain tests, such as pH balance trials and urinalysis probes for medical diagnostics. Companies have simulated over 400 different types of creative urine for these experiments.

This demand has grown up primarily due to concerns regarding disease transmission associated with natural bodily fluids where direct contact is necessary between researchers and test subjects.

Can TestNegative Detox Drinks Have Side Effects On My Body?

TestNegative detox drinks contain various natural ingredients such as herbs, fruits, vegetables, and other nutrients. These ingredients can help provide your body with essential vitamins and minerals that can support healthy digestion and eliminate toxins from your system.

While TestNegativedetox drinks are generally considered to be safe with few to no risks associated with drinking them in moderation, there are some possible side effects that you should keep in mind.

Does TestNegative Deliver Genuine Products?

Yes, TestNegative is a website that delivers genuine products to its customers. This is evidenced by the multiple customer reviews that have been left on the website.

The reviews show that the products delivered by TestNegative are of high quality and are as described on the website. Therefore, it can be concluded that TestNegative does deliver genuine products to its customers.

Why Does Synthetic Urine Require A Heat Activator?

There are a variety of reasons why synthetic urine may require a heat activator. The most common reason is to ensure that the synthetic urine is close to body temperature. This is important because body temperature can fluctuate, and if the synthetic urine is not close to body temperature, it may be rejected by the body or produce inaccurate results.

Additionally, some substances in synthetic urine can break down at lower temperatures, and a heat activator can help prevent this. Finally, some employers or organizations may require that all samples be submitted at body temperature, so using a heat activator can ensure compliance.

Why Do THC Metabolites Attach Themselves To Fat Cells In The Body?

When you eat cannabis, your body converts the cannabinoids into THC metabolites, which travel throughout your body until being eventually eliminated in the urine.

Many people don’t realize that these important compounds do more than just cause a buzz or give users a “high” – they actually attach themselves to fat cells in the human body and become stored there for an extended period.

This process is known as lipid accumulation and occurs because cannabinoids have a chemical structure similar to fats and oils.

THC metabolites remain attached to fat cells for long periods of time because lipids break down at a much slower rate than other elements in the body.

This means that traces of THC can remain in the bloodstream for days after consumption, even if the user isn’t feeling any effects from those traces.

Additionally, because lipids don’t decompose easily, they can accumulate over time with regular cannabis consumption – leading to higher concentrations of cannabinoids specifically on fat cell surfaces.

Can Herbal Pre-Cleanse Capsules Help Remove THC From My Body?

Herbal pre-cleanse capsules are supplements, typically containing ingredients such as Milk Thistle, Dandelion Root Extract, etc., and are purported to have detoxifying properties.

These capsules should be taken before attempting any detoxing program and can supposedly remove toxins and impurities from the body.

How Long Does THC Last In My System?

The length of time that THC remains in your system will depend on several factors, such as the amount consumed, the frequency of use, age, gender, and BMI.

According to studies from The Journal of Analytical Toxicology, urine tests can detect low concentrations of THC-COOH for up to 8 days after the last usage for an occasional user and up to 30 days for regular or heavy users.

Approximately half of all participants who reported abstaining from marijuana use had detectable amounts of active THC metabolites within 3–4 days after last usage and generally had no active metabolites in their bodies after 16 days – which means they test “negative” on a common urine assessment.

How Else Can You Detox From THC?

If you’re looking for effective ways to detox from THC, there are several natural methods that may help. One way is by increasing the amount of water you drink, which can help remove toxins more quickly since water helps dilute them in your urine stream.

Exercise is also another great way to expel unwanted substances from your body since it increases circulation and allows more oxygen into your system, which speeds up metabolism and makes it easier for your liver and kidneys to process and rid your system of waste products like THC.

Additionally, including high-fiber foods in your diet, such as leafy greens and fruits, can aid in the digestion of metabolites, thus speeding up their elimination from the body.

Finally, sweating more through exercising or using a sauna can also help release more toxins via perspiration, meaning you’ll excrete them quicker than normal.

Final Thoughts

If you are at risk of being caught in a drug test, synthetic urine products are the only solution. These goods have been in the market for years, and TestNegative is the best reseller of the world’s most well-recognized synthetic urine maker. In a word, give TestNegative a chance; it might just help you evade a positive drug test.
