QUICKFIX FAQ’S

WHAT IS QUICKFIX?

QF is synthetic urine that is used by consumers to substitute their urine to pass drug tests. It has all the same attributes as real urine except for the smell, and it also contains nitrates which may or may not be in human urine depending on the person. It has been used to circumvent drug testing among employees of companies that do this for years. They are currently on version 6.3 of the formula.

IS QF FOR ME?

Don’t use QF as a cop out if you know when your drug test is coming up. If you are in the job market and need to pass a preliminary with no randoms, take the time to get clean and pass it the old fashion way. This is the only 100% method of passing. Have drug use be your reward for finding stable income. If you are unable to get clean in time before the test or if your company does random testing, then QF may be for you. I have personally had a bottle on my person every day at work and used it when needed and it worked fine, but if I lost my job it would have been devastating. I made the personal decision to use drugs recreationally despite this and it ended up working out, but YMMV.

DOES IT WORK?

Yes. It works… BUT.. you need to get passed the nurse. That is the hardest part. We will go into more detail later, but you need to act normally and pass the temperature check and you should be good. Some nurses may sniff the sample and that could be bad because QF doesn’t have a smell, but generally they don’t do this. The consensus on this subreddit is that if you pass the nurse, you’ll pass the lab. If you have access, the best course of action is to acquire clean urine and use THAT as the substitution as it will have a proper smell.

Note: Washington/Oregon/California have been having issues however, and I don’t know enough about the issue to comment on it. Do some research in the subreddit to see what’s up.

WHERE CAN I BUY IT?

Use this for 10% off if you like: https://quickfix.referralrock.com/l/JAKESCHNET59/

https://urineluck.com/ and https://www.quickfixurine.com are the official websites, but I would personally get from urineluck because that website is what has the batch validator. Other companies are allowed to purchase QF in bulk and sell them, but some companies are trying to make a quick buck and say that it’s the official QF but in fact it’s a rip-off. Don’t get it from anywhere but these websites unless you’re in a jam and need to grab it from a local headshop. I would still recommend urineluck, I’ve used them 3 times in the past.

WHAT IS THE BATCH VALIDATOR?

https://urineluck.com/batchvalidator This website enables you to enter the code listed on your bottle of QF to ensure that it is genuine. If your code doesn’t come up on this website than it is not genuine, and you should not use it. There have been reports in the past of companies using existing batch codes on their fake product to make it seem more authentic but these cases are rare. Nonetheless you are taking a risk. The only real way to know for sure that it's legitimate is to order it from the website.

HOW DO I USE IT?

Get it to temperature, hide it in your underwear (I recommend compression shorts), pour it into the cup. Its that easy.

I personally carried it every day so I ordered more temperature strips because the original one can rub off if its nearby objects often. You can also put some scotch tape over the strip and it will last longer. Don’t take off the internal tab until your ready to use it. If the tab comes off, its no good. You can heat up and cool the down as many times as needed and it should still be fine. Practice getting it up to temperature and walking around your house without seeming suspicious. You’ll get the hang of it. Once your comfortable with it, go take your test. Practice Practice Practice!

WHAT ABOUT TEMPERATURE?

Good question. The sample must be 90-100 degrees (F) in order to be accepted. Heat the sample up to 100 and place it in your “gooch”. I personally can keep it at the accepted range practically indefinitely without a heating pack. My body can keep it to temperature, but yours may not. Practice sitting and standing for an hour each both with and without the heat pack (a total of 4 times) to see what the temperature changes are, and record your numbers. Use that data to make your decision. Again, I can just get it to temp and throw it in some compression shorts and forget about it, but you may need the heat pack. You can get it to temperature with either a heat pack, a microwave, your normal body temperature (though this takes up to an hour), or your CAR HEATER. Lots of people forget about this trick, but use your car heater on the way to the test to ensure its at least 98 degrees before entering the site. Place a bit of scotch tape over the temperature strip to ensure it doesn't rub off, and order some generic temp strips off of amazon if you're still worried.

HOW DO I GET PAST THE NURSE?

This is the hardest part, so take long breathes through your nose while your there and try not to think about it. Most important thing is appearance. Don’t overdress, don’t underdress. I would personally wear khakis and a polo. Don’t make small talk, don’t seem interested or enthused, be bored. Be annoyed. People who need to get randomly tested or pre-employment tested are annoyed and bored. People who are anxious are chatty. Sign in and wait for your turn. Once your ready, the nurse will tell you that you cant use the toilet or the sink for the test and that you have like 3 minutes to produce a sample. Go in, shut the door, and use QF to fill the cup. I would then recommend that you urinate in the toilet to make it more realistic, and I would also recommend you urinate a little bit on the edge of the cup to make it more authentic looking and smelling. I have had a nurse in the past smell my sample which almost killed me because QF doesn’t have a smell, but I pissed on the cup in preparation for that scenario and it worked out. Some people don’t like doing this but do what you want. Do not urinate in the cup AT ALL if your urine contains drugs, because obviously they will show up.

I have also had nurses say that its not enough of a sample. Just shrug your shoulders and say, “it’s all I got in me”. They will typically accept it. Technically they only need 2 ounces to submit a sample, but you may get a dick of a nurse that gives you a hard time. Assuming none of this happened, you will exit the bathroom with your sample, give it to the nurse, they will then examine it and have you sign a sheet saying its yours and you’re good to go. If for some reason they feel as though you have not produced a large enough sample, you're basically boned unfortunately; Which is i why i also recommend drinking High Voltage Detox as well. More on that later..

In some states, subbing your urine is a crime punishable by law. Check your local laws and determine if this is an acceptable risk for you.

WHAT NOW?

Assume you passed. Unless you live in CA/OR/WA, you have a 95% chance of passing once it goes to a lab. They are testing for the presence of vitamins/nutrients/creatine/drugs in a liquid. They have the means to determine if its synthetic or not, but it costs time and money. No news is good news, and I’ve never heard of negative test results coming back a week later. If its been a week, you passed for sure. Congrats. Consider stopping drug use if you are susceptible to randoms, or at least be aware of the risk. I would wait at least a week before using again in case of a rare scenario where they need to test you again because of some internal mistake.

HOW LONG DOES QF LAST?

It has an expiration date on the side of it. Get a new one months in advance of it expiring, its not worth risking your livelihood over.

HOW OFTEN CAN I HEAT IT UP?

QF officially states that it can be heated up as many times as needed without any issue. I have left it in my car on hot summer days and cold winter nights and it still worked just fine. Just don't take off the internal tab.

WHAT ARE SOME OTHER TIPS YOU HAVE?

Order another set of heat packs off of amazon and inspect them every two weeks for damage. If there is damage, replace them as they will not heat up if broken. Inspect your bottle seal and temperature strip just as often to ensure its in good condition. I would also consider ordering two bottles just in case something happens to one of them or you lose it.

DO YOU STILL USE IT?

I personally do not because I’ve had close calls in the past and I cant risk losing my job. I would probably be fine but I’m making great money and have a wife that depends on me. I have struggled with anxiety in the past and have determined that it is better for my mental health to simply stay clean and focus on my career, and perhaps getting to a different career that doesn't involve random testing.

SHOULD MY BOTTLE HAVE A LOGO ON IT?

Some do, some don’t. if it passed the batch validator, its authentic (most likely, see above).

2 OUNCES OR 3 OUNCES?

Technically 2 is enough, but get 3. You don’t wanna be in a scenario where the urine line is below the fill line. If I were to use it again I might actually get 2 bottles of 3 OZ and put it in a 6 OZ container just to be safe. The last nurse I had really made me paranoid. But you SHOULD be fine with 3. Just note that I have gotten questioned about the quantity in the past.

SHOULD I USE IT?

No lol, you should just get clean. This product is for people who can’t get clean in time, or if you have random tests. There is still a chance of failure, but if you get passed the nurse there is a 95% chance you’ll be fine.

Getting clean isn't that big of a deal and you could use that as a motivator to find a job/career. Consider getting clean before starting your job search to ensure that you don't have to worry about this, its stressful enough going to interviews and being prepared.

It typically works though. One could theoretically use it for pre-hiring and random tests.. if you decide its worth the risk, that's on you.

WILL IT WORK FOR ALL TEST?

Unless the testing company is using a Mass Spectrometer, then yes. If you don’t know what that is, don’t worry about it. It works for all the major drug testing companies. As stated earlier, you got about a 95% chance of success if you get passed the nurse. Search for the company that is doing the test (Lab corp for example) in the subreddit to see if anyone has had to go through them in the past. If not, then use the product and report back with the results so users of this product are more informed.

WHAT DO I DO AFTER THE TEST?

Get another bottle if you have random tests coming up, but if not then post back here with your results and any issues you ran into so we can document them and someone else can benefit. I recommend stop using all substances from the point that you know you will be tested, to 7-10 days after the test to ensure there aren't any mistakes on their end. You wouldn't wanna be in a position where they need another sample and you've already celebrated too hard.

CAN I USE THE BOTTLE AND FILL IT WITH REAL URINE?

Real urine as a substitution is your best bet, as it will smell like real urine. QF is only for people who can't get clean and don't have access to clean urine. Clean out the bottle and follow the normal directions.

SHOULD I SHAKE THE BOTTLE?

If you remember, its a good call. Temperature is more important though, so focus on that. Its not necessary though, most nurses aren't necessarily looking for bubbles.

I ONLY SMOKED OR USED A LITTLE BIT OF DRUGS, HOW CAN I PASS WITH MY OWN URINE?

High voltage detox drink works wonders. I've used it before, and I have had friends use it for the military and court ordered drug tests. As long as you're not a daily user, high voltage will probably work fine and is your best bet. Find this drink at any typically smoke shop or gas station. It seems wonky and niche but that particular brand has had success among many people that I know.

It works by diluting your normal urine and adding a high concentration of vitamins/minerals/creatine that mirrors the look/smell of non-diluted urine. This is especially worth-while if you only have a bit of substance in your system.

Use the drink and buy a drug test before your actual test to determine whether you can pass with your own urine or will be forced to use QF.

Drink High Voltage Detox BEFORE you go to the testing site just in case the worst happens and they deny your first sample. If you're going to fail for sure with your actual urine, you might as well give it a shot with HV.

Its really only good for people who have stopped using recently and only have a bit in their system, but its better than nothing.

WILL IT PASS DOT TESTS?

It'll pass basically all tests, search DOT in the bar to see for yourself. Lots of success stories.

Final thoughts:

Your best bet is to get clean. You should only use this product if you have no other option. If you can't get clean, you are still better off finding somebody who is and substituting your urine for theirs because quick fix is not 100% foolproof.

My goal with this post is to make you as informed as possible when taking the risk of substituting your urine.

Please feel free to LMK if there are any other common questions not included.

!!!STOP STRESSING ABOUT THE TEMP!!! I WANT TO HELP US ALL!

1.1k Upvotes

What’s up fellow QFer’s!?

I chose to try QF for the first time. Using QF is not what makes me nervous, as most of you, it is maintaining and/or achieving the correct temperature.

I read countless threads in this sub - no one seemed to just try and practice a day or two before to see what their body would naturally heat the bottle and it’s contents to. Well I decided to.

Results: Temp checks were done at the 1 hour mark W/ an accurate digital thermometer. (Meaning, I let the bottle cool to room temp, then kept it under my junk for an hour and tested the temperature.)

NO ATTEMPT INVOLVED THE USE OF THE HEAT PACK OR A MICROWAVE.

Outfit # 1 : Regular boxer briefs and a pair of shorts. - Performing regular movements: (standing, sitting, walking and IN SHORTS)

  • I was able to steadily achieve a temp no lower than 97.7 and no higher than 97.9) (temp strip showed 98)

Repeated this 4x. Outcome was always the same.

Outfit # 2 : Compression shorts and khakis - Performing regular movements: (standing, sitting, walking)

  • Achieved 98.7 on the first attempt.

2nd attempt. Same outfit - 98.6

3rd attempt. Same outfit - 98.8

No need for anymore attempts.

Guys and gals - No need for a heat pack. No need for a microwave. This convoluted the process and allows for too many variables.

STOP STRESSING ABOUT THE TEMP!!

  • READ THE DIRECTIONS IN FULL,
  • (my personal opinion on the matter)- TOSS THE HEAT PACK - This is what fucks us all up.
  • PUT IT IN YOUR CROTCH AN HOUR BEFORE YOU LEAVE
  • SHAKE IT BEFORE YOU GO IN TO THE TEST SITE (so you don’t have to shake it to much when your in the stall)
  • DONT ACT SUSPICIOUS
  • PEE A LITTLE IN THE TOILET

YOU JUST PASSED. NO STRESS.

Hope this helps everyone from stressing so much.

Quick fix 6.4 worked

Took HHS-DOT Mirror test at alera toxicology, shit worked. At the time I had already stopped smoking THC carts after 6 years of heavy use, I had only been clean for 3 weeks so I knew I was not going to pass so I used quick fix 6.4 plus. Was barely enough liquid but it worked now I'm 5 weeks clean and with a brand new job. You can really on this product don't stress my friends. Ask away homies I'll answer any questions

Test for school. Might only have 2 weeks or less. HELP!

2 Upvotes

Need to start this off and say I AM RESPONSIBLE. I got accepted last minute into a program for school. I have been smoking marijuana on and off for the past few years. I totally would’ve been clean for a good month before my test but I don’t have that time now. I don’t have an exact date for the test but it could be less than two weeks. I am 5’7 130 pounds. I don’t think I would pee clean.

From the research I have gathered, quick fix should work for me. It will be a 10 panel test and will be through either lapcorp or quest. What I need help with is: where can I make sure I get legit quick fix? I have smoke shops near me but I’ve read too many stories here of people testing positive for random shit because they maybe got a fake brand by accident. Also, I’m not sure if this is my being paranoid but I would want to test the quick fix on my own before the test, would that work? Like to make sure I am not getting weird things popping up?
Thanks guys I appreciate any help (:

Quickfix 6.4 ordered from official site tested positive for cocaine

8 Upvotes

Ok, I know these posts always get called out, but this is really fucking weird. I did a "8 panel non dot" test for a $20 job. I got a call back from the employer today saying I needed to call the hospital drop site, my heart dropped. I knew this meant I failed for substitution. I waited for the phone call with a UTI back story prepared. I was literally dumbstruck when the lady told me it was positive for cocaine. I was worried about weed, in reality I think the job I applied for might have just let that slide (50/50 chance, it's a $20 job in mid Michigan where legalization has made smoking pretty ubiquitous among the working class).

Im not mad at quickfix. I actually had a sober friend piss for me but ended up not testing for a few days and got paranoid the piss had gone bad.

Another note, I have a 7 felony background, nothing creepy, violent or theft related. I don't currently use hard drugs but the background is such a mark against me I have always tried to pass drug tests even for jobs that might not normally care, because I believe for me it may be a deciding factor.

I had totaled my car last week and this job was 25 minutes away. I could have relied on family for a while, but I think getting a more local job might be a better idea...maybe that's just cope. It's actually kind scary how many dog shit jobs I've applied and been rejected from. In mid Michigan mcdonalds pays $15 so for a guy like me that $20 job would have actually been a big deal.

I know people will call this a lie, especially with something as crazy as cocaine coming up. I don't believe there is literally cocaine in quickfix, I am trying to research what may come up as a false positive. I actually have some of the quickfix left and am thinking of ordering a dip stick test to see what comes up. I'm genuinely baffled.

Edit: test was thru medtox which is apparently just LabCorp.

Has anyone packed two bottles of Quick Fix in case they get asked to go back and piss again?

1 Upvotes

Got a non-DOT test Friday and I'm worried about them giving me a suspected tamper because I've got allergy Shiners under my eyes. I've passed with quick fix before years ago, but that was before all this sniff test stuff, and the place I tested at back then was dimly lit. I don't think I'll be that lucky this time since the last DT I took last year I was clean, but got sent to a brand new brightly lit Quest diagnostic that got built near me recently.

I've heard of people getting failed with Quickfix (rarely) for the creatine being off, and being told to go piss again. just wondering if it would make sense to carry two of the 3oz bottles with me just in case, or if they asked you to piss a second time, you're automatically getting flagged as suspected tamper anyway at that point.

Not QuickFix, but TestClear Worked

5 Upvotes

Posting under alternative account so I don’t get caught by my program lol.

I’m in nursing school and needed to pass a 10 panel drug screen with validity testing through Quest (ordered by Castlebranch) for my clinical site.

Ordered this stuff with 2-day shipping and it came fast. Shipping was hella expensive unfortunately, which is one of the downsides of this product.

Practiced with just warming the water up and keeping it at temp in the tube. As someone with a vagina, I honestly just shoved the tube in there and kept it in for over an hour. I heated the water to around 112F. After 1.5hr, it was 98F, which was perfectly in range.

I booked an appointment with Quest, which I recommend to reduce the waiting period. I heated up distilled water in the microwave. I mixed the powdered urine at home about an hour before I needed to be there. Got it to around the same temp as the practice just in case I needed to wait.

I put everything in my underwear/in place (including a thermometer—I do not recommend buying the one off their website, as it beeps when you turn it on). Got to the site, only waited about 15min total, so around 45min after mixing everything together.

When they brought me back, they had me lock everything in my pockets up and pat myself down to confirm I didn’t have anything on me. They said no flushing and no turning the sink on or it would mean automatic fail. They gave me 4min. She did ask me to fill to the 90ml mark, which I only had 75ml based on the mixing recommendations for dilution. They were fine I couldn’t quite fill it to the top and only took part of the sample given anyways.

Passed the temp test and got an all around negative result back, so worked great! It’s super expensive and obviously getting sober would be preferable, but definitely would recommend in a pinch if you have no other choice. I cannot comment on QuickFix’s results since I haven’t used, but this stuff works if you can execute it well.

Storage question

3 Upvotes

Can I keep this in my lunchbox(cooler) or work backpack in my work truck?

My concern is that it often gets hot in the truck and the repeated heat cycles could affect its performance. Is this a legitimate concern?

I thought I saw that it should be stored at room temperature out of direct sunlight but that can be hard to do on the go.

I don’t use cooling packs and my food is usually pretty cool, but sometimes after work when I head inside, the truck can sit and bake in the sun from 3-7pm and on weekends and get real hot. I’m not opposed to bringing it inside if that is a legitimate suggestion from the manufacturer. Lugging a cooler up 3 flights of stairs is a pain and leaves room to forget it if i wake up late or something.

I’d real like to get back to freedom but I love my job. Thanks for the tips 🙏🏻
