Certo, a common household fruit pectin, can be a quick fix for passing a urine drug test. Its effectiveness has some scientific backing.

However, it’s important to note that this method is not foolproof and reviews are mixed.

I’ll guide you through how to use Certo to maximize your chances of passing a urine drug test.

I’ll also explain how this method works and discuss more reliable alternatives.

How to use Certo and Gatorade to pass a drug test: Step by step instructions

When it comes to timing, use the Certo method 2-4 hours before your drug test. It typically takes 1-2 hours to start working.

So, ensure you have enough time before the test for it to take effect.

Certo’s effectiveness for a urine test lasts up to 5 hours. However, it needs about 2-4 hours to kick in, and its peak effectiveness is around 2 hours after consumption.

That’s why it’s best to take it 2-4 hours before the test.

Step by step instructions

For occasional users and panel drug tests:

  1. Mix a pack of Certo with a bottle of Gatorade 2 hours before the test.
  2. Urinate at least 2 times before heading to the test.
  3. An hour before the test, drink another bottle of Gatorade.

For regular users and lab tests:

  1. Optionally, mix a pack of Certo with an electrolyte drink and drink it the night before the test.
  2. 6 hours before the test, take 10 grams of creatine monohydrate. Alternatively, take 10 grams of creatine ethyl ester 3 hours before the test.
  3. Take 200mg of vitamin B12 or B2, 3 hours before the test.
  4. Mix 27oz of Gatorade or another sports drink with a packet of Certo, shake it well, and drink it.
  5. Drink about 30 oz of water more before your drug test.
  6. Remember to urinate frequently.
  7. Test yourself with a home drug test before going to the test center.

Hints to improve chances of passing

Improving your chances of passing a drug test with Certo involves a few additional steps. Here are some tips:

  1. Pre-test Preparation: The night before your drug test, mix a packet of Certo with water and drink it. This helps remove more drug metabolites from your intestines, preventing them from entering your bloodstream.
  2. Variety of Sports Drinks: While Gatorade is commonly used, you’re not limited to it. Other sports drinks like Powerade, BodyArmor, and Hoist can also be effective. The key is to choose a drink that helps maintain electrolyte balance.
  3. Personalize Your Liquid Intake: The exact amount of liquid you need varies based on factors like smoking habits, body weight, age, and more. It’s a good idea to do a few practice runs at home to determine the right amount for you.
  4. Morning Diet: On the morning of your drug test, eat carbohydrate-rich foods. Options include pasta, porridge, pizza, or even a chocolate bar. Carbs help halt the breakdown of body fat, preventing THC stored in fat cells from being released into your bloodstream.

How does Certo help pass a drug test

To grasp how Certo aids in passing a drug test, let’s dive into the basics of THC metabolism.

When you consume marijuana, THC enters your bloodstream, either through your lungs if smoking or your stomach if eating edibles.

It then travels to the liver, where it’s metabolized, or broken down, into metabolites. These metabolites are excreted into both the bladder and intestines.

Interestingly, about 70% of THC metabolites are excreted into the intestines, with the remainder going to the bladder.

From the intestines, some THC metabolites are reabsorbed back into the blood, a process known as enterohepatic circulation. The rest is excreted with feces. Meanwhile, THC from the bladder is excreted with urine.

Why marijuana stays in your system for so long

THC is highly fat-soluble, meaning it binds to fat cells. Once in the bloodstream, it reaches various body tissues and binds to these cells.

About 70% of consumed THC is trapped by body fat. When the body breaks down these fat cells for energy, THC is released back into the bloodstream.

This process is slow, causing THC to continuously circulate between body fat and blood. Only a small portion is excreted, which is why THC can linger in your system for weeks or even months.

What is Certo


Now, let’s talk about Certo. Certo is a type of fruit pectin, known for its high fiber content.

This fiber is what makes it an effective gelling agent.

It’s this unique property that plays a key role in its use for passing drug tests, as I’ll explain further.

How exactly the Certo method helps to pass a drug test

how does Certo affects marijuana metabolism and help to passs a drug test

The Certo method’s effectiveness in passing a drug test hinges on several key factors:

  1. Absorption of THC: A significant amount of THC is reabsorbed into the blood through the intestinal walls. From there, it can enter the urine and be detected during a drug test. Certo, being a fruit pectin, absorbs THC in the intestines, preventing it from re-entering the bloodstream.
  2. Increased Urination: The Certo method involves drinking a lot of liquid, leading to frequent urination. This process helps flush THC metabolites out of your bladder, temporarily reducing the concentration of THC in your urine to below detectable levels.
  3. Effect of Gatorade’s Sugar: Consuming sugar raises insulin levels, which in turn stops the breakdown of fat cells for energy. Since THC is fat-soluble and stored in body fat, it’s released slowly into the blood. Drinking Gatorade, therefore, blocks the breakdown of these fat cells, preventing THC from being released into the blood and urine.
  4. Dilution and Specific Gravity: Drinking a lot of water can dilute marijuana metabolites in the urine, reducing their concentration. However, this also dilutes other urine components, potentially flagging the sample as diluted. Drug tests often check for specific gravity, which is the concentration of minerals and elements in the urine. Gatorade contains minerals and vitamins that help restore the urine’s specific gravity, allowing it to pass this aspect of the drug test.


In summary, the Certo method combines THC absorption, increased urination, the effects of sugar on fat cell breakdown, and the balancing of urine specific gravity to improve the chances of passing a drug test.

Does Certo Sure Gel work for opiates?

Yes, Certo Sure Gel can work for opiates, just as it does for other substances. This method helps flush out various drug metabolites from the urine.

These can be metabolites from opiates, marijuana, cocaine, or others.

It’s important to note that if you’re taking any prescription medication, this method will also flush those from your urine, and they won’t show up on the test.

The downside – results are not guaranteed

While the science behind this method is sound, results are not guaranteed. The effectiveness of the Certo method can vary based on factors like body mass, frequency of marijuana use, and other personal variables.

What works for one person may not work for you.

I recommend doing a couple of dry runs at home to estimate the exact amount of liquid you’ll need before the actual drug test.

Another drawback is that using this method can lower creatinine levels in your urine.

During a drug test, your urine undergoes a validity check, which includes assessing specific gravity and creatinine levels.

While Gatorade can restore specific gravity, it doesn’t address low creatinine levels.

To counter this, we’ve updated the method: you should take a creatine supplement several hours before the drug test.

Again, I can’t stress enough the importance of doing dry runs at home. Purchase urine validity check strips and drug test strips.

Experiment to find the right balance of liquid and creatine that works for you.

Consider the consequences of failing a drug test. If passing is crucial, don’t skip these trial runs.

Failing could mean losing a job or missing out on a significant opportunity. Don’t risk your future.


When it comes to passing a drug test, there are several alternatives that can be more reliable than the Certo method. Let’s explore some of these options.

Fast Marijuana Detox Kit

The Fast Marijuana Detox Kit is a same-day solution for passing a drug test. It works by temporarily flushing marijuana metabolites from your bladder.

This reduces their concentration to below detectable levels, allowing you to pass your drug test with confidence.

The kit includes all necessary vitamins and minerals to maintain specific gravity, creatinine levels, and urine color within the normal range.

This means your urine will also pass the validity check. It starts working in 60 minutes and is effective for up to 5 hours.

Plus, it can be delivered overnight if needed.

Synthetic urine

Using synthetic urine is another reliable way to pass a drug test.

However, it requires careful management of the urine temperature, as it must match body temperature when submitted to the test collector.

It also requires a discreet method to sneak it into the drug test.

Permanent Detox

Permanent Detox is a method that removes all traces of marijuana from your body.

This approach requires abstaining from marijuana and other drugs, and following a healthy diet and regimen to speed up the removal process.

This method is permanent, it means that all traces of marijuana will be removed from your body until you use it again.

The Certo and Gatorade method for passing a drug test does have a scientific basis and can work.

However, it’s crucial to understand the risks involved. Reviews on this method are mixed, and its effectiveness is not guaranteed for everyone.

Additionally, there’s no certainty that your urine will pass the validity check.

If you’re considering this method, I strongly recommend doing a few dry runs at home.

Purchase validity check strips and drug test strips to gauge the method’s effectiveness for you personally.

But remember, if the outcome of the drug test is critical – perhaps for a life-changing job opportunity or for probation – it’s important to weigh the risks carefully. In such high-stakes situations, you might want to consider more reliable alternatives.

These include the Fast Marijuana Detox Kit, synthetic urine, or undergoing a permanent detoxification process.

Each of these options offers a different level of reliability and commitment, so choose the one that best aligns with your needs and circumstances.
