Certo (Sure Jell) Method Guide – Does Certo Work For Urine Testing?

If you’re looking to pass a drug test easily and cheaply then the Certo method will be something you’ll hear about pretty soon in your investigations. Also known as the Sure Jell method, it was common around a decade ago when there were less high-quality detox products readily available.

So is Certo good enough to pass urine tests? I’m going to answer that key question for you now. But more than that, this is a complete guide not only on how to complete the Certo method, but also telling you if it’s scientifically possible for it to work, and what you could use instead to pass a modern drug test.

What Exactly Is The Certo Drug Test Method?

The Certo method uses cheap household products to help remove cannabis toxins from the body so that you can pass a drug test. Note that I use the word cannabis. That’s because this drug test method is specifically designed to remove cannabis metabolites in the body. It’s not designed for other types of drug metabolites.

So unless you’re looking to cleanse yourself of marijuana smoking signs, or the use of novel cannabinoids such as Delta 8, then you can skip to the end of this guide where I tell you about three methods that will help you to pass advanced urine drug tests.

Why It’s Believed The Certo Drug Test Method Could Work

The idea behind the Certo method is that the fruit pectin creates a sort of gel-like substance in the digestive tract that traps drug metabolites and prevents them from being excreted in the urine.

Fruit pectin is a dense form of dietary fiber. So by consuming it in large amounts quickly, we are creating lots of bile and drawing a ton of marijuana metabolites potentially into the bowel very quickly. Instead, they are removed faster in your stools. The large amounts of water consumed with the Certo method help to dilute and flush out the kidneys and urine, reducing the concentration of any remaining metabolites.

If you’re wondering why we want to draw cannabis metabolites to the bowel, it’s because we need to. You can’t do this with other types of drugs, because they universally exit through the skin or (predominantly) through the kidneys and bladder. But up to 60% of cannabis metabolites actually exit the body through the bowels, because cannabis metabolites are a different shape and readily attached to fat cells in the body.

That’s why the Certo/Sure Jell method has some potential to work, but only specifically for the removal of cannabis toxins faster than can be achieved naturally.

Certo drug test hack

This Is The Full Certo (Sure Jell) Drug Test Method Instructions

Let’s now go through the full Certo drug test hack and instructions, so you can see what’s involved. This is the “classic” method that’s been around for nearly 2 decades.

Materials Needed:

  1. Certo or Sure Jell – These are brands of fruit pectin, commonly used in home canning to thicken jams and jellies.
  2. Sports Drink – A drink like Gatorade is most recommended.
  3. Water – Large amounts of water are consumed as part of the process.
  4. Creatine Supplement – This is used to help maintain normal creatinine levels in the urine.
  5. Multivitamins – Especially containing B vitamins, to help give the urine a normal yellow color.

Method (stage I – night for your test):

The night before the test, mix one packet of Certo pectin fiber with a large bottle of sports drink. Shake the mixture thoroughly until the Certo is fully dissolved. Drink the entire mixture down swiftly in about 10 minutes. Then follow this up by drinking around 30 fluid ounces of water (about a liter) over the next hour.

Make sure you do this a couple of hours before bed, so you can then urinate a couple of times to clear your bladder and clean out toxins before you sleep.

Method (stage II – day of your test):

On the morning of the drug test, three hours before your test, repeat the Certo and sports drink mixture as I’ve already explained above. This includes drinking the water and urinating for an hour afterward.

At the end of the hour, you will mix the creatine with water (around 8 fluid ounces) and consume that, while also taking a multivitamin pill. Doing this will ensure that creatinine appears in your diluted sample that it contains vitamins and is stained the correct color (requires B vitamins). Some say taking one aspirin tablet also helps.

You’ll then urinate a couple of times in the hour after that, and then get to your test to submit your sample as quickly as possible.

The Famous Certo Gatorade Method

Gatorade is just a sports drink. The main reason to drink it is that contains sugars, caffeine, and electrolytes.

Pretty much any sports drink that contains those could be used instead of Gatorade. It’s just always mentioned because it’s a big brand found in the USA (even though it’s not actually found in many other countries with the same popularity). You don’t actually need to drink sports drinks at all. You could use water, and consume it with an electrolyte pill that will contain the key ingredients of zinc, magnesium, and salts.

However, especially if you’re in the USA, it’s easier to just grab a bottle of Gatorade if it’s not something that you wouldn’t react badly to.

The ” Certo Drug Detox Method ” Is A “Home Remedy” Drug Test Solution

The Certo method is a home remedy method. That means it uses easily obtainable household ingredients to try and pass a urine drug test. Other such home remedy methods have been touted for decades.

These are some of the most common (unproven methods) you’ll read about:

  • White wine vinegar
  • Apple cider vinegar
  • Green tea
  • Other types of specialist tea
  • Bleach (yes, you read that right)
  • Baking soda and water
  • Cranberry juice
  • Aspirin tablet
  • Citric acid

The problem with all of those home remedies is they are absolute nonsense. None of these are scientifically proven. There is no way on earth they will flush out drug toxins from your body any quicker than water would.

Plus, drinking excess liquid will promote urination and is not only going to leave your sample diluted (easily spotted in validity checks) but drinking too excess can expand cells in the body and cause overhydration which can lead to significant fast-moving health problems.

Does The Certo Drug Test Method Work?

You’re probably already pretty aware of where I’m going to go with this, and the answer I’m going to give you. Does the Certo drug test method work – not a chance in hell? There is no scientific evidence behind it.

These are the exact reasons why it won’t work:

  1. Although the Certo/sure jell is rich in fiber, and it will draw more cannabis metabolites to the bowel, it won’t do anything to speed up the removal of toxins through the bladder, other than drinking the large amount of liquid involved in it.
  2. The large amount applicable significantly dilutes your sample. It will also not accelerate the flow of toxins fast enough to create a gap in the toxin flow. That’s a crucial point. You’re not trying to get rid of all the cannabis metabolites, because you can’t. You’re trying to flush them out faster than natural, so it takes your body several hours to catch up.
  3. Just taking some creatine and a vitamin B is not going to fool modern validity checks on your sample. They will spot that it’s been diluted because of the frequent urination and adulterated with a simple dipstick test.
  4. If you’re looking to get rid of any other drugs than marijuana then you are just shit out of luck anyway, because it won’t flush them out any faster than would simply drinking water.

Put all that together, and although the Certo method can draw THC metabolites into the bowel faster than natural, and it will help get rid of more cannabis metabolites, it’s not going to help you pass a drug test. It’s not a complete natural detoxification process method because it doesn’t address drug metabolites in the urine, nor the fact that your urine will be totally lacking in balance.

My advice is simple: forget the Sure Jell detox method of the get-home remedies to try and cut corners for a urine drug test. The only things that will help you are specialist products, so let’s talk you through them in detail now.

Best Way To Get Genuinely Clean To Pass A Drug Test: Toxin Rid Pills

If you’ve got time before your drug test, then the easiest way to pass is to get genuinely clean. You can do this with high-quality detox pills called Toxin Rid (click here for our review).

Available exclusively from Test Clear, they are the most potent pills on the market that contain a range of natural ingredients that help speed up the removal of toxins in the body by up to 60%. Toxin Rid is available in course lengths from one day through to 10 days, and you should tailor the course length you choose the amount of drug metabolites you suspect you have in your body.

To help you, broadly these are the brackets you should work within when choosing a course length:

  • For lower toxin exposure select the 1 – 3 day courses
  • For moderate toxin exposure let the 3 – 5 day courses
  • For higher levels of toxin exposure, select the six-day or higher courses
  • If you are a regular daily weed smoker then select the full Toxin Rid 10 day course

Obviously, it’s not easy to recommend the exact course length you will need, because certain substances require more time than others, but if you are a regular daily cannabis smoker then I would always go for the seven day course or the 10 day course if you have the time before your test.

Basically, by a course that matches the length of time you have in days before your test, or you suspect you will get.

Using Toxin Rid is really simple, and you just follow these easy instructions:

  1. Follow the principles of a natural detox process, living healthily, exercising, and drinking plenty of water.
  2. Every day of the pill course, during the first five hours of the day you are awake, take three pills per hour with 8 fluid ounces of water each time. Then live well, drink plenty of water, and urinate regularly throughout the day.
  3. On the last day of the pill course, two hours after the last detox pills, mix up half the detoxification liquid. Drink that smoothly over 10 minutes, then abstain from drinking or eating for two hours.
  4. Two hours later repeat the process, and abstain from drinking or eating for another two hours.
  5. For cannabis users, use the fiber supplement on the day after the detox liquid. This works like fruit pectin (Certo) by drawing more cannabis metabolites into the bowel in the same way.
  6. Check yourself with a home drug testing kit before going to the testing center.

Because you’re not doing all this just before your urine drug test anyway, and it’s more structured in replacing things lost by the body within the pills, alongside a potent detoxification liquid, then your sample will still be natural and balanced during most drug test validity checks.

Best Way To Mask The Toxins To Pass A Drug Test: Rescue Cleanse

If you’ve got lower levels of drug metabolites in your body, and not much time before your test, then a detox drink might be the best way to go.

Detox drinks don’t detox you that much, other than pushing out toxins faster than your body can naturally at that moment in time. That creates a gap in the flow toxins of a few hours, during which your urine sample will be clean of them. Rescue Cleanse also floods the body with things found in urine, like creatinine (creatine) and vitamins and minerals. These flush through the body as well, keeping the fresh urine testing naturally. My NB2 recommendation would be Detoxify mega clean detox drink.

Rescue Cleanse or Mega Clean on its own probably won’t work for long enough if you have higher levels of metabolites in your body though.

The combo strategy is then the best:

Do a 24-hour detox, massively accelerated by potent Toxin Rid pills. That will leave fewer toxins flowing out of the body on the day of your test, meaning Rescue Cleanse or Detoxify Mega Clean has less work to do.

Best Way To Pass An Unsupervised Drug Test: Quick Luck

Drug tests are mostly unsupervised, meaning that there will be nobody in view, nobody will be looking at you, and usually nobody even in the same room when you submit your urine sample.

You’ll know in advance if it’s a supervised test unless you are caught with something that you have tried to smuggle in, in which case they can then demand the test is supervised and brackets you don’t have to agree).

So for most drug tests, you could use synthetic urine, because nobody is going to be observing you submit your sample.

Quick Luck synthetic urine is the best product on the market. It has the following characteristics:

  • Contains 14, chemicals found in urine
  • Contains the correct amount of creatinine, urea, uric acid
  • Is within the correct specific gravity and pH ranges
  • It looks, froths, and smells like urine

So Quick Luck will get past even the most rigorous validity checks and will then obviously pass the immunoassay (urinalysis).

The biggest reason why people submitting fake samples get caught though is because they submit it outside the correct temperature range (legally a sample has to be between 90°F and 100°F).

Quick Luck synthetic urine uses heat activator powder instead of a heatpad. This allows you to simply transport the premixed synthetic urine to the venue, and then prepare it discreetly just before you go in. Tap in about one-quarter of the activator powder and shake it until it’s dissolved. Watch the temperature strip, and if you don’t get a reading, repeat the process with small amounts until you do.

Easy to use, complex, and it will fool close expert human scrutiny, making Quick Luck the best solution for unsupervised drug testing. If you are new to synthetic urine check out our detailed guide.

Where To Buy The Products You Need To Pass A Modern Drug Test

As you can see, the Certo drug test method is a load of nonsense. No home remedies will pass drug tests, because even if they manage to get you clean they will leave you horribly adulterated and you will fail the validity checks. Combining certo with other detox techniques also won’t work.

So let’s tell you where you can buy the products I’ve explained about above, which will definitely help you to pass a drug test:

  1. Quick Luck synthetic urine is available direct from Clear Choice, through their test negative webstore.
  2. Rescue Cleanse detox drink is also available from Clear Choice, through their website at test negative
  3. Toxin Rid detox pills are available directly from Test Clear

Don’t forget, if you are using any detox kits, drinks or detox pills, that you will need home drug test kits to see if you are clean before you submit your sample. These home drug test kits are affordable, and both Test Clear and Clear Choice have them for sale, so you can order them at the same time.

 

Certo Detox Method FAQ

What is Certo used for?

Certo is a fruit pectin that is used as part of something called the Certo method. It’s also referred to as the Sure Jell method, which is another brand of fruit pectin. Basically, it doesn’t matter what brand of fruit pectin you use. The idea is that the high-fiber of this fruit pectin creates bile and draws cannabis metabolites into the bowel at a faster rate, leaving less to pass through your kidneys and into your bladder.

How effective is Certo?

The Certo method is effective at drawing higher levels of cannabis metabolites into the bowel for removal. But it’s not a complete solution. It does absolutely nothing to address the fact that the large amount of liquid you drink with this method, even when you also take a creatine supplement and multivitamin, cannot disguise the fact that you have adulterated your sample. It is not effective either for complete removal or temporary masking of toxins after drug use. Overall, it is not particularly effective and shouldn’t be relied on at all.

Where can I get Certo?

 

Certo, like another brand called Sure Jell, is simply fruit pectin. It’s found in the bakery and cooking area of almost any supermarket. You’ll also usually get a supermarket’s own brand of fruit pectin that’s far cheaper than brands like Certo.

I really wouldn’t advise you to use Certo though, as it’s highly inefficient for removing THC metabolites. A far better option is to use Toxin Rid pills in the lead up to your drug test, and then use Detoxify Mega Clean or other detox drinks on the day of your test to mask any remaining ones.

How to take Certo?

To take Certo to get rid of cannabis metabolites you have to use it as part of something called the Certo method. It’s also known as the Sure J ell method. It involves multiple drinking of Certo fruit pectin, along with Gatorade, multivitamins, and creatine. All you need to know is that it doesn’t work. You need a professional detox drink like Rescue Cleanse instead, preferably backed up by a short course of Toxin Rid pills to eliminate more toxins before the day of your test.

How does Certo detox your body?

Certo drug test hack doesn’t detox your body. It helps draw more THC metabolites to the bowel so that the total of cannabis metabolites removed from the body is more than usual, but it doesn’t effectively remove them all. Nor is it any good for other types of drug other than cannabis. A good quality detox drink like Rescue Cleanse is the most effective way of masking the toxins. Home remedies like the sure jell method are totally inefficient and should never be trusted when good quality products are available instead.

How to use Sure Jell to pass drug test?

The idea with the Certo method is to consume it over two days, alongside Gatorade sports drink, multivitamins, and creatine supplements. Doing this is meant to draw moredrug toxins into the bowel for faster removal, and will help to keep your urine appearing natural rather than diluted.

The problem with this claim is it’s not true. It can’t do all of that successfully. At the very least, the dilution of your sample will be noticed and it won’t bring metabolites in your urine under the detectable levels. You need a proper detoxification pill course like Toxin Rid and a proper detox drink like Rescue Cleanse to mask the remaining toxins instead.

How long does Certo last after taking it?

Certo is not a masking strategy. So there is no max time it will last. It’s meant to work to remove cannabis metabolites permanently. Although the idea is that potentially you could mask the toxins on the day by flushing out your bladder and then using multivitamins and creatine alongside the slowing down of metabolites appearing in your urine to mask for a few hours, in reality, it’s not a viable strategy.

How long does Certo work for urine test?

The Certo drug test hack is actually meant to be a permanent detoxification method, not just a masking strategy. However, the idea is that it should also slow the flow of metabolites into the bladder, and disguise the fact you have flushed yourself out. Unfortunately, in reality this simply isn’t true. The Certo method is a poor quality home remedy that will not help you pass drug tests unless you get incredibly lucky.

The Sure Jell Drug Test Hack: How To Use Certo Pass A Drug Test

This is a complete guide to the Sure Jell drug test hack. I’ll give you the complete Sure Jell/Certo detox method (the full and original one) in detail.

I’ll explain the scientific background to how this hack could actually work in the body, and how drug generally metabolites work inside your as well. Using Certo to pass a drug test could be a cheap and effective way of doing so, but does it actually work? I’ll answer that question for you clearly.

As well as telling you exactly how to use the fruit pectin method and where to buy Certo, also I’m going to tell you about professional alternatives to passing a urine drug test as well.

What Exactly Is The Sure Jell Drug Test Hack?

The Sure Jell drug test hack uses Sure Jell, Certo, or similar fruit pectin along with some other easily obtainable ingredients to try and pass a urine drug test.

The idea is that it draws cannabis metabolites to the bowel in order to eradicate them more quickly, and flushes out the bladder so that you test negative even with drug metabolites still in your body.

So here’s the thing. It only really works for cannabis metabolites. No other type of drug metabolites (waste product) are shaped in the same way, and don’t get drawn out through the bowel as frequently.

Lots of people have tried Certo drug test methods because they don’t want spend money, are convinced by what they read online, or are desperate.

If you’re desperate, Reddit and other forums are full of the same questions “ does certo work for probation drug test” , or “ how to not lose custody of your kids”, or perhaps the toll taken by something like domestic abuse has led you astray, then it’s something you could grab at because it seems so simple to do.

How Drug Metabolites Work In The Body

Whatever type of drug you take, it eventually works out through your body mostly through the bladder and bowels.

Mostly, the detectable substance in the body that is looked for during drug tests is a metabolite. This is a waste byproduct created when the drug itself is metabolized. This isn’t always the case, but it is mostly.

With cannabis metabolites things a little different. They are a different shape to most types of drug metabolites, and because of this they claim to fatty cells in the body.

This means that they can hang around for a lot longer, and they can detach and exit randomly through urine and stools.

In fact, studies have shown that chronic weed smokers can take up to 4 months to eradicate all the metabolites caught up in the body.

Also, because they are attached to fatty cells, cannabis metabolites work their way out through the bowels in a way that most drug metabolites don’t. In fact, up to 60% of them exit through the bowels, rather than the usually more than 90% exiting through urine for other drugs.

Is There Any Scientific Evidence That Fruit Pection To Pass A Drug Test Work?

Certo and Sure-Jell are brand names. They are both fruit pectin products. Fruit pectin is a concentrated fruit extract that is high in fiber.

I hit your body with this intense hit of fiber, you are creating more stills, and creating more bile. This process can draw more cannabis metabolites into and out through the bowel.

Also, you mix the pectin with a sports drink like Gatorade. Because sports drinks are high in dextrose and sugar, carbohydrates, they can enhance this move through the bowels, and also slow the breakdown of fat to enhance this, and stop more of the metabolites from moving through the kidneys and into your urine.

So yes, for cannabis, there is scientific evidence that it could work to pass a drug test. However, that leaves a couple of crucial problems:

  1. Can it get rid of all the drug metabolites in your body so you test clean?
  2. If it can’t get rid of all metabolites, can it flush them out and keep your urine balance appearing natural for a few hours, so that you can pass?

How To Use Certo/Sure Jell To Pass A Drug Test (Full Method)

Let’s talk you through the full Sure Jell drug test hack to you can see exactly how it works.

This is the original method, not the copied and changed rubbish that most websites serve up.

You will need the following to do the fruit pectin drug test method:

  • 2 x bottles of Gatorade (or similar sports drink)
  • 2 x Multivitamin pill
  • 10 g creatine powder
  • 2 x standard aspirin pills
  • 2 x Sachets of fruit pectin

Once you gather the ingredients, these are the Certo detox steps you need to follow.

  1. The night before your test mix-up one bottle of Gatorade with half the fruit pectin. Drink it down over five minutes. Then sit on 16 fluid ounces of water over the next hour. Urinate several times before bed.
  2. On the morning of your test, don’t eat anything. Six hours before your test, mix-up the other half of the pectin with Gatorade and drink. Drink 8 fluid ounces of extra water over the next hour and urinate frequently.
  3. Four hours before your test take an aspirin pill. Also, take the multivitamin pill and half of the creatine. Take these with 16 fluid ounces of water. Continue to urinate as often as possible.
  4. Two hours before you leave take the second aspirin pill and the second multivitamin pill. Also mix up and take the other half of the creatine. Do this with another 16 fluid ounces of water.
  5. One hour before the time of your drug test make sure you take a home drug test to ensure that it has worked.

Does The Certo Detox Work For A Urine Test?

Whether you call it the Sure Jell hack, Certo drug test method, the Certo detox, or whatever, it doesn’t really matter. The key question is does using fruit pectin in the method described above get rid of cannabis metabolites so you can pass a drug test?

Although this can draw out more cannabis metabolites through the bowels, and it can accelerate the removal of cannabis toxins faster than usual, it cannot get rid of them all.

So you’re looking at whether you can flush them out for long enough and retain the balance of your urine using the multivitamins and the creatine, while also potentially generating a false negative using aspirin.

Look, it could work. The science is there. But it only works for cannabis metabolites. Plus, you’ve probably got about 75% chance of it working.

75% is not great odds, and those are my best-estimated odds if you do everything right and get lucky. For me, it’s more of a 50-50 toss of the coin when submitting your sample as to whether you pass or not. To me, that’s a huge risk when there are far better methods out there.

Methods To Pass A Urine Drug Test

Hopefully, you can see that the Sure Jell hack is a huge risk and should only ever be done if you have literally no other options open to you.

Thankfully, there are three great strategies you can use to stand an incredible chance of passing a drug test. With the three methods about outline, better than 90%, and even close to 100% with a bit of good luck.

1. Accelerated Natural Detox

The absolute surefire way to pass is to not have drug metabolites in your body at all. That way you simply can’t fail.

There are a couple of problems with that though. First, if you are a regular user, you are unlikely to have more than a week’s notice, and often far less. Second, cannabis metabolites can hang around a lot longer than other types.

Natural detox can take several weeks. Even then you aren’t completely safe. That you can accelerate this and push out more toxins using high-quality detox pills in order to get completely clean fast.

Toxin Rid is the only brand I would recommend. They aren’t cheap, but they offer huge potency and flexibility.

You can get a single day course through to 10 day course. If you’re a chronic user or smoker I suggest the seven or 10 day course (preferably 10).

Do a natural detox and take the pills each day. Toxin Rid can half the amount of time it takes you to get completely clean. Just be warned that for the first few days your urine and stools will look really bad as it pushes out the toxins at an accelerated rate.

2. High-Quality Detox Drink

Another great strategy, especially if you have only short notice until your drug test, is a high-quality drug detox drink. Don’t be misinformed here, a detox drink doesn’t detoxify you. It’s a masking agent.

Detox drinks work by flushing out the toxins more efficiently than water can alone. They also flood the body with the major things found in normal urine, so that some gets passed through as waste. That way, the urine is toxin free and appears balanced for a few hours. As more toxins work their way through into your bladder, you will test positive again. Usually, you’ll get three or four hours clean.

You can extend this time, and ensure a greater chance of success by teaming the detox drink up with 24 or 48 hour detox. You can also use a one or two-day course of Toxin Rid to push out far more toxins.

Eye doing that, there will be fewer toxins on the day of your test, meaning less work for the detox drink, and more time potentially clean to submit your sample.

The two best brands are Rescue Cleanse and Mega Clean. I would go for Rescue Cleanse unless you can get Mega Clean with the six pre-rid pills combo (only available from Test Clear) which will give you a more potent 24-hour detox. If you are interested in more detox product reviews, I highly recommend ndtv.com’s How to pass a drug test guide.

3. (Best Method) High-Quality Synthetic Urine

I’ve left the best method until last. Although getting clean naturally is actually best, it’s very rare you will be able to achieve this in time. So, using high-quality synthetic urine is the best overall method because you’re never going to get caught with drug metabolites in your sample because it’s fake.

As long as you use a high-quality brand, it will pass the validity checks and not be detected.

Quick Luck is the best brand on the market. It was expensive $100 but is highly complex. Not only does it contain 14 chemicals found in urine, but it’s also perfectly balanced for pH and specific gravity. It also smells, froths, and looks like urine.

The second best is Sub Solution. It’s actually almost identical to Quick Luck (the same company makes both).

The only difference is that it’s a powder, so you will have to mix it with filtered water to create your sample. It’s not a big deal, but it is an extra step that would really be out for use at work or on-the-spot drug testing. However, it is $15 cheaper.

Both Quick Luck and Sub Solution use heat activator powder rather than a heating pad. You don’t need a microwave, and you don’t have to transport it with a heat pad strap to it.

Just before you in submit your sample, simply tap about one-third of the heat activator powder into the sample, and gently shake it until it dissolves. This action raises the temperature, and you just keep adding a little bit at a time and watching the strip over a minute each time until it reads at close to 100°F (but not over).

If you can’t get your hands on Quick Luck or Sub Solution, or you can’t afford them, then Quick Fix is a viable alternative and costs just $30. It’s a very basic formula that only contains creatinine, urea, and uric acid. But it is balanced for pH and specific gravity and looks like urine.

It also uses a heatpad, which will mean slightly more variability and a chance on keeping it within the correct temperature range (three 90°F 100°F). If you take a flask of hot water with you then you can pour it over the sample before you enter the building if it’s cooled.
