Certo Drug Test

For individuals who enjoy a smoke, even in states where marijuana is legal for recreational use, employment drug testing is a pain in the ass. According to Statistics Brain, 56% of American employers make pre-employment drug tests mandatory. The annual cost of these tests is $3.7 billion. If this seems like a lot, bear in mind that employers lose an estimated $85 billion a year because of employee drug use.

Urine tests are by far the most popular and marijuana is the most commonly found drug. Therefore, if you’re close to the job of your dreams, use weed, and are called in for a drug test, your only hope of passing it is by using one of the myriads of detox methods online. The Certo Drug Test detox has been championed as one of the best ways to get clean in a hurry; but is it all hype or the real deal? Read our full review to find out.

What is Certo?

‘Certo’ is a generic name for Fruit Pectin with the trademark held by Kraft. The company also has another brand called ‘Sure Jell’ which is the same thing as Certo but with different packaging.

Certo has been available in the United States for over 100 years but has only recently become associated with detox.


Fruit pectin is a naturally occurring polysaccharide in fruits and is extracted from sweet fruits such as peaches, pears, apples, and berries. All polysaccharides consist of long-chain monosaccharides and they are a digestible fiber. You will typically find fruit pectin in jellies and jams because of its ability to gel things together. As it is a highly soluble fiber, it does a good job of detoxifying your system. It is excreted through the system via your feces.

How Certo or Fruit Pectin Can Help Detox Your System

certo drug test review
One of the main misconceptions about Certo is that it traps toxins by coating your stomach. In reality, it works as a typical fiber by enabling your body to absorb and expel the toxins via your fecal matter. As it forms into a gel, it absorbs more liquids than ‘normal’ fibers. As toxins that normally leave your system via urine end up in your stools, Certo is theoretically a great way to pass a urine drug test.

Here’s a more detailed explanation of how Certo detoxes your system. Fruit pectin ensures the toxins are trapped and broken down into smaller metabolites that are easier to remove. The process typically takes 60 minutes and can last for 3-5 hours in total. Eventually, the toxins are released and leave the body via your urine.

Certo is high in fiber and carbohydrates; the latter results in an insulin boost in healthy adults which causes the body to store calories for energy rather than using them. The body also burns or metabolizes fat for energy. When fat-soluble toxins are released from the fat cells, they end up back in the bloodstream, saliva, urine, and other fluids. The fast-acting carbs in Certo cause an insulin spike which prevents fat burning for a short period and shuffles the herbal detoxing minerals and nutrients in the concoction.

Finally, Certo absorbs the toxins that are naturally released from the body via stools, urine, and other body fluids. Toxins find it easier to leave the body via fluids but Certo’s fiber absorbs the fluids in your intestines and stomach and this action results in toxin release via solids. Unlike other ‘quick fix’ detoxes, you have to begin the Certo plan 24 hours before the test.

Here’s how the other components of the Certo Drug Test work:

Water There is no better natural detox method because when you remain hydrated, the body knows there is no need to retain fluids and begins the process of removing toxins from the body. However, you have to be careful not to drink too much water. Overhydration depletes the minerals found in body fluids so when you consume too much water, you flush out the toxins and nutrients. If a drug test shows a lack of minerals in your urine, questions will be asked.
Vitamins Healthy urine contains B vitamins and since the detox process can wash out some nutrients, you need to replenish them to avoid suspicion.
Creatine  Popularized by bodybuilders, creatine is a mineral found in the body naturally and you normally get enough through fish and red meat. It is present in your urine and once again, detoxing can deplete it so you need to consume some to make your urine look genuine.

Certo Drug Test Instructions

Certo Drug Test

The Certo Drug Test detox is pretty easy to follow. You’ll see a variety of different instructions online; ignore them! This is the method and ingredients most likely to work.

You Will Need

  • Two packets of Certo (Sure Jell or Fruit Pectin will do).
  • Two x 32oz sports drinks (909 ml x 2). Gatorade is popular.
  • Creatine Monohydrate.
  • Multivitamin.
  • Vitamin B2 (not strictly necessary).

Once you have the above, the steps are pretty simple.

  1. Drink as much water as you can in the two days or so leading up to the drug test. Water will help flush out your toxins and send what remains to your intestines.
  2. Mix one packet of Certo with one of the sports drinks. Give the mixture a shake and drink it before going to bed on the night before the drug test.
  3. On test day, drink as much water as you can about three hours beforehand.
  4. 1-2 hours before the test, mix the second packet of Certo with the other sports drink.
  5. Consume it along with the multivitamin and B2.

In theory, the Certo method should keep you toxin free for at least three hours.

If you’re in a hurry, consume a packet of Certo, the 32oz bottle of Gatorade, and a similar amount of water an hour before the test. It won’t work as well as the 24-hour window but it could help you scrape by.

Does Certo Detox Drug Metabolites?

Yes! That’s why it is such a popular detox method for marijuana users trying to pass a urinalysis. As you know, THC is the psychoactive compound in cannabis that’s famed for getting you high. It is one of over 100 identified compounds in weed. THC-COOH is the name of its metabolite so when you consume marijuana or any THC product, your body breaks it down into THC-COOH.

These metabolites begin flowing through your body and bloodstream and while a small amount is expelled, most get absorbed by lipids and it ultimately gets stored as body fat. It remains there until it is gradually re-released into your bloodstream when you metabolize fat for energy. After its re-release, it becomes expelled via your urine, sweat, saliva, and feces. While your body naturally detoxes, the process takes weeks which is bad news for weed users facing a drug test.

This is where Certo comes in handy. Fruit pectin can speed up the detox process and it is effective for users of marijuana, cocaine, and opiates in particular. It is important to note that Certo’s detoxing capabilities are not scientifically proven.

Things to Watch Out for When Purchasing Certo

Don’t waste your money on fancy branding, fruit pectin is all you need and it is widely available in most large grocery stores. The entire method is inexpensive so don’t be fooled into spending cash you don’t need to. There is NO guarantee that the Certo Drug Test detox will work but you will definitely fail if you make one of these mistakes:

Leaving it too late Certo takes at least an hour to work and you are best advised to use two doses; one the night before and one around two hours before the test.
Over hydration As well as flushing out nutrients, drinking too much water will make you feel ill and you could throw up the Certo mixture.
Skipping the Sports Drink The electrolytes in sports drinks are a crucial part of the Certo method.
Not using creatine  Creatine should be found in urine so if you flush it out without replacing it, your test will be flagged.

Final Thoughts on Certo Drug Test Detox

The Certo Detox Method seems so simple that it’s hard to believe it could work. Will it work for you? Well, there are a number of factors that dictate the effectiveness of the method including your size and fitness, body type, age, metabolism, and marijuana usage.

Furthermore, there is no scientific evidence to back up the claims and cynics believe it is the large volumes of water involved that help people get through drug tests. While it is possible that the fiber in pectin helps temporarily keep toxins from leaving your system via urine, there is also a chance that simply drinking large quantities of liquid dilutes your urine to the point where you can pass a drug test. In any case, if you do decide to use the Certo Drug Test detox method, make sure to test it out first!

    I mean it works if you follow directions

    Okay so I started at 7:45am one pack of the Certo mix in a 32oz Powerade and downed the entire thing initially I was aiming to drink 8 bottles of water equaling out to a gallon after but when I got to my 5th bottle of water I was damn near sick so I set 8 alarms every 15mins to down a bottle of water however as I said didn’t make it to 8 only got to 5 but it’s okay you must listen to your body when I was on my third bottle of water I had to shit (it was like diarrhea) then after consuming 5bottles of water every 15mins after downing the Certo and Powerade I set one last alarm one hr after drinking my 5th bottle of water then I took an at home drug test and got a fainted line which means yu passed basically saying yea there’s drugs in you but it’s under the threshold which for marijuana is 50ng my actual drug screening is tomorrow but that’s all I got

    Needs time

    CERTO always helps me pass a drug test, but usually I get to know about a month prior to the test. So that ways CERTO is good. I have never used it on emergency basis.

  3. Dana Battle
    Great CERTO

    Although CERTO is a great detox, I used it once and passed my test, however, I also feel it is a great cleanser for the body. I had never to appear for a drug teat after that one test, however I usually detox myself with CERTO once every two to three months, as I feel it does very good to my body. Great Product.

  4. I’m employed for another week
    Inconclusive test but can buy time

    This will at least buy you time for another test.

    5’9 Female 147 lbs moderate-fast metabolism – daily smoker 2+ years

    My test came back inconclusive- followed this to a T – I’m pretty sure my HR dept was just giving me a hard time since it was most likely a light negative and they decided to send it to the lab for testing. But I’m still employed.

    I took a drug test 30 minutes prior to my actual one and had a medium-light negative which is still a negative. Definitely your best shot.


    This caused a major migraine, nausea, diarrhea, and dizziness for me but I do have a sensitivity to sugar.

    The sugar free one tastes worse though I got it down BUT the original surejell made me puke – and I slowly drank it over 30 minutes.

    Best of luck!

  5. Negative Results
    Works like a charm

    Followed completely…worked like a charm..came back negative but flagged…for being diluted…or over hydrated…light but daily smoker

  6. Chi
    Quick Question

    So i’m a heavy smoker, and i have a drug test coming up on 6/19 and it’s 6/13.. of course like any person would i’m going to stop smoking until my test. The last time i smoked was today… and i smoked a pretty heavy amount. If i drink that stuff today will it be out of my system by then? or does it HAVE to be 2 days before?

    1. -

      I noticed you took your test today. Did you pass?

    2. Vince


      The effectiveness of the Certo Detox Drug Test depends on the person’s metabolism, weight, age and other factors. For best results make sure you follow the instructions explained in the article. Good luck!

    There are two schools of thought on why it works, the first is that the fruit pectin binds with the bile in your intestines, and the THC-COOH that has already been released from your stored fat is in that bile. Normally consuming fluids would flush out some of that THC-COOH, and it would be present in your urine. The fruit pectin binding with the bile in your intestines prevents THC-COOH from being flushed out through urine for a 2-3 hour window because of this. You will defacate it out with the fruit pectin rather than urinate it out, because the pectin binds with the bile that contains THC-COOH. It gets stuck in the pectin, so it’s difficult for fluids to pull it out into your urine.

    The second, is the fruit pectin causes an insulin spike, and prevents fat from being burned for a short window, which severely limits your bodies ability to release THC-COOH from the fat in your body into your intestines. This means while it’s binding to the bile, your body won’t be releasing more into your intestines, so the THC-COOH isn’t being replenished for a short window.

    The combination of these two effects benefit someone who wants to dilute their urine and lower the THC-COOH levels to below the 50 ng/ml threshold.

    Now after reading the above, you should be able to realize that this technique is far more effective if you abstain before a drug test. That does not mean it won’t work on short notice, but stop smoking if you’re applying for a job, or the second you know you have a test coming up. Drink plenty of water in the preceding days to ensure your body flushes out what’s already present in your intestines and kidneys. Give yourself the maximum head start possible to lowering the THC-COOH levels in your intestines and kidneys. The more THC-COOH molecules that are there will add to the possibility of testing above the 50 ng/ml threshold even when diluting. Drinking the water beforehand ensures you pee out what’s there, so that the Certo can clean up the little bit that’s left over for a short window.


    Diluting is basically drinking the maximum amount of fluids your body can process so that your urine contains more fluids than waste products for a short time. Obviously the more fluids present, the less likely that THC-COOH molecules will be there in high concentrations. Again, you want to test below the 50 ng/ml threshold. Your first pee of the morning will be loaded with THC-COOH if you’re a heavy smoker. Even an occasional smoker could test above the 50 ng/ml threshold with undiluted urine depending on how often you smoke, and if you’re smoking oil or concentrate it’s even more likely to linger in your system for longer. There’s simply more being stored in your fat for your body to filter out.

    Of course, there are methods to detect diluted urine. Even simple non-lab tests have test strips in them to test pH, Creatinine, and specific gravity. These strips change color to give a good idea if you have attempted to beat the test. pH you don’t have to worry about so much, it’s a wide range and even pure water tests within the correct range for urine. Specific gravity and creatinine are the ones you need to worry about.

    Finally, if your urine is clear, it’s an obviously diluted sample, and they will know it. That doesn’t mean they won’t process it, or that you’ll fail, but they will know that it’s a heavily diluted sample, which just leads to the likelihood of closer inspection or re-testing in the near/immediate future. So you’ll want to worry about having yellow pee when you dilute as well.


    Supplies Required:
    5 32oz Gatorades (If you dilute with Gatorade, the specific gravity will come back normal because electrolytes sugar/sodium are present in urine, pure water has a lower specific gravity than urine because there are barely any electrolytes.)
    1 Box of Certo liquid fruit pectin (Will contain 2 pouches)
    15 Grams of Creatine powder or capsules (Will ensure creatinine is present in diluted urine)
    2 Multivitamins (Make urine yellow)
    Vitamin B Complex (A blend of vitamin b2, b3, b6, b12, etc.) (Guarantees diluted urine will be yellow when combined with Multivitamins)
    Coffee (It’s a diuretic, and makes you pee, helps you pee regularly when you’re drinking heavy amounts of liquid)
    1 Home Drug test for cannabis (Optional, but gives you incredible peace of mind)


    *WARNING: DO NOT drink more liquid than your body can handle. Overhydration can kill you. Your kidneys can remove about 32oz of fluid per hour, hence why you spend 4 hours diluting instead of chugging tons of liquid at once before your test. Drinking gatorade rather than water is important to prevent overhydration during the steps below.

    Step 1: The night before the test, right before you go to sleep – mix 1 certo liquid pack with 1 32oz gatorade. You will need to drink about 1/5 of the gatorade first to make room for the certo. Make sure you get every drop of certo out of the pouch. Put the cap back on the Gatorade, shake it up until it gets all foamy. Drink every drop. When you’re done, put a bit of water in the bottle and shake it up to drink any foam that remains.

    Step 2: When you wake up drink 1/2 liter of plain water.

    Step 3: 4 hours before the test, drink 1/2 of a 32 oz gatorade, and take 5 grams of creatine with it.

    Step 4: 3 hours and 30 minutes before the test, drink 1/2 of a 32 oz gatorade.

    Step 5: 3 hours and 15 minutes before the test, drink a strong cup of coffee. Try to defect at some point before you take the certo later on, but be sure to take the certo on time regardless.

    Step 6: 3 hours before the test, drink 1/2 of a 32 oz gatorade, take 5 grams of creatine, 2 multivitamins, and 1 serving of your vitamin b complex with it.

    Step 7: 2 hours and 30 minutes before the test, drink 1 32oz gatorade mixed with certo. You will need to drink about 1/5 of the gatorade first to make room for the certo. Make sure you get every drop of certo out of the pouch. Put the cap back on the Gatorade, shake it up until it gets all foamy. Drink every drop. When you’re done, put a bit of water in the bottle and shake it up to drink any foam that remains. You should be peeing pretty regularly before this step, it will take at least 1 hour to start peeing dilted/clean.

    Step 8: 2 hours before the test, drink 1/4 of a 32 oz gatorade.

    Step 9: 1 hour 45 minutes before the test, drink 1/4 of a 32 oz gatorade.

    Step 10: 1 hour 30 minutes before the test, drink 1/4 of a 32 oz gatorade.

    Step 11: 1 hour and 15 minutes before the test, drink 1/4 of a 32 oz gatorade.

    Step 12: 1 hour before the test, take 5 grams of creatine with either water or gatorade.

    Step 13: 30 minutes before the test, you should be peeing yellow by now, if not before. You have consumed a gallon of fluids already, so pee it out as needed so you don’t feel the urge to go. If your pee is yellow, you are ready for your test.

    Step 14: If you decided to optionally buy a home drug test, test yourself to see if your pee is clean. This is totally optional, but if it’s clean you can walk in without being nervous, and the peace of mind goes a LONG way. You’ll be relaxed, and seem pretty carefree like you’re some guy who doesn’t do drugs and knows for sure he’s going to pass. It could have the opposite effect if it comes back not clean, but i’d rather not show up for the test and lose a job offer, than pee dirty and have on record somewhere. Do what you feel is best for you, but knowing if you’ll pass or not lets you make the best decision for you.

    Step 15: Show up to your test. When you pee in the cup, be sure to pee a bit in the toilet first, then give your sample mid-stream, don’t finish in the cup, give just above the minimum amount, and finish peeing in the toilet. The beginning and end of your pee are typically contain more waste products than the mid stream, so this is just en extra precaution.

    Step 16: Don’t be an idiot and smoke right after the test. Wait until it comes back negative in case they decide to re-test.

      Now a believer!!!

      Strainmaker I followed your instructions to a T and it worked!!! The second line was very faint (after not smoking for 5 days) right now I’m at 10 days and still have another two weeks until my work drug test so I’m sure it’ll work! I’ve read online that it’s important to eat before you take the Certo the night before so it sticks to your bile. What are your thoughts on that? Do you think it’s nessacary?

  8. Donta
    I need the certo method directions

    Can someone whos passed there ua please explaine the exact directions for the certo method please.

  9. Dee
    It works!

    I have been smoking for the past 15 years, daily. I am definitely a certified bud smoker.
    I used the Certo method to pass a UA for a job at a drug rehab facility.
    I followed similar instructions (minus the B vitamin and Creatine) and I passed that test with no problems. I’m now applying for another job at a hotel company that requires a UA and will b using this method this time around.
    New job, here I come!!

    Holy f*ck I did this along with exercise, diet, and drinking massive amounts of water over the span of 4 days and passed. I even took the certo too early, like I took it at 9:35 am and took the b complex/b12 pills about an hour half later. I took the drug test at 3:28 because of a bunch of misunderstanding and paperwork. The urgent care worked at a damn glacial pace. I’m not saying wait as long as I did but if you too took it too late/early drink water and make sure the piss is yellow. Don’t stress dudes.

  11. smoker743

    My drug test is today at 5pm and i just recently found out about this certo method. should i take one certo+gatorade drink now (its 10am) and one 2 hours before drug test, or is it better to skip first one and drink just one mixture before the test? or should i drink double certo+gatorade mixture before the test?
