Does Magnum Detox Work? Our Honest Review of This Brand


This review was last updated in April 2024.

If you’ve ever frantically looked for synthetic urine because of a surprise urine drug test at work or you’re applying for a job with a new company, then Magnum synthetic urine probably came up high in your search results.

However, as is often the case with products that have a big marketing budget behind them, they can seriously lack actual function and reliability. And because Magnum Synthetic Urine seemed to pop up everywhere, we were a little suspicious.

It turns out that suspicion was a bit justified.

Our Initial Findings

Let’s start with the only positive we have on Magnum Synthetic Urine. This is the only artificial product you can buy in retail stores.

This means that you don’t have to wait 2-3 days for Magnum Synthetic Urine to come through the post. This is great if you’re in a rush due to a surprise drug test, and you have no other product options left on the table.

Failed report

Like many other brands, Magnum Synthetic Urine (also known as Magnum Detox Novelty Urine) was designed to imitate baseline human urine samples. For the purposes of this Magnum Synthetic Urine review, the brand names may be used interchangeably.

It comes with a vial of uric acid, a heating pad, and an enclosed rubber band.

Magnum Synthetic Urine features a relatively straightforward kit that is easy to use for first-timers. With each package, you get 4 ounces of the artificial sample, which allows you to take up to 4 tests.

Most important of all, and worryingly, is the reliability of the Magnum Synthetic Urine. Unfortunately, it does not work reliably enough for our liking.

You simply can’t trust the effects of the Magnum Synthetic Urine when it comes to most synthetic urine review tests. After a thorough test, one of the main weaknesses is that it can produce too much creatinine when heated up for too long.

Due to the improvement of tests in most certified lab facilities, if your piss does not have the correct amount of creatinine, then it will be an instant warning signal as fake pee. It will be red-flagged for closer scrutiny, and that will almost always result in a failed test.

This means landing your dream job is over, or even worse, losing your current job with lifestyle changes happening overnight.

One thing to mention, despite the name, this is not a detox product that can be used to clean your own pee. We find that most of such detox products are inconsistent in passing a urine test and often result in disastrous disappointment.

Because of this, I always recommend synthetic urine products over detox solutions.

Instructions on How to Use Magnum Detox Synthetic Urine:

  1. Shake the container before mixing and heating.
  2. Next, heat the fake urine sample in a microwave for around 10 seconds.
  3. Measure the temperature of the sample using a thermometer. Make sure that it’s at least 94 degrees Fahrenheit. If not, put it back in the microwave for an additional 5 seconds.
  4. Once you have the right temperature, shake the bottle to prevent it from settling at the bottom. Next, remove the container’s heating pad and then shake it well. When you’re ready, take the heating pad and attach it to the side of the bottle opposite the temperature strip. Use the enclosed rubber band to do this, and do not remove the pad.
  5. If you can’t seem to heat your fake piss using a microwave, then another option that you can try is to activate the heating pad by shaking the container to mix the contents. Once you have done that, attach the heating pad to the side of the bottle opposite the temperature strip using the enclosed rubber band. It usually takes around an hour to heat a sample to about 90 to 100℉ using the heating pad. As in step 4, you must not remove the heating pad.
  6. Shake the bottle thoroughly before using the solution. When you’re ready, flip up the spout on the cap and squeeze the contents out. At this point, the only thing left for you to do is to mix the fake urine with uric acid.

Related Reviews:

Please remember once you mix Magnum Synthetic Urine with uric acid, you will only have seven days to use before it goes bad. Using it after that point will lower your chances of passing a drug test even more. Without uric acid, the drug test will flag your human urine sample as fake urine.

What Sets Magnum Detox Apart from Other Fake Urine Brands?

What sets Magnum Deetox apart from other brands is the separation of uric acid from other ingredients in its synthetic urine formula. This separation is crucial to ensuring that the product performs well in laboratory tests. Real human urine consists of various components, including but not limited to creatinine, urea, uric acid, bacteria, vitamins, minerals, and other trace elements derived from food and drink.

The activation procedure, in which the uric acid is combined with the other ingredients, is what gives Magnum Detox its effectiveness. This activation process transforms the solution into a more realistic urine-like substance. Before activation, the components remain inert and cannot pass laboratory tests designed to detect authentic urine. By combining the uric acid with other ingredients, Magnum Detox enhances the resemblance to real urine, increasing the likelihood of passing such tests.

Will Magnum Detox Synthetic Urine Actually Pass a Drug Test?

Magnum Detox Synthetic Urine may not reliably pass a drug test due to issues such as inconsistent creatinine levels, lack of uric acid, temperature discrepancies, and potential degradation over time, making it a less preferable choice for such purposes.

What this means is that when a lab scans your Magnum synthetic urine sample for any signs of foreign artificial substances, they will quite easily detect you have used a fake urine sample, due to either too much creatinine, lack of uric acid, or the wrong temperature.

Another problem with Magnum Synthetic Urine is its ability to completely imitate pee after it has gone bad or when it has been diluted with other substances.

Old synthetic urine samples, for example, have low creatinine levels. This is why we recommend that you should have a small portion of your Magnum synthetic urine tested before officially submitting it to a lab.

Additionally, if you mix the uric acid vial to the synthetic urine sample, it goes bad in 7 days. Using it beyond that period will surely result in a failed drug test.

Another issue that you should be aware of is that aside from inconsistent results, there are plenty of fake Magnum Detox Synthetic Urine being sold all over the Internet. Always try not to buy yours from an unofficial seller as they will most likely sell you a fake or a substandard synthetic urine product.

But in most cases, the user has either missed one of the steps or misunderstood the instructions. This happens quite a lot in this field. Surprise, surprise…

However, with Magnum Synthetic Urine, there are just too many online reports of failed tests.

Frequently Asked Questions

Does Magnum Synthetic Urine Have Uric Acid?

Yes, Magnum Synthetic Urine has uric acid, which is contained in one of the included vials. When you mix Magnum Detox fake urine with the included uric acid vial, make sure to use it within 7 days, or else, it will go bad and will most likely fail your drug test. Uric acid is an important component of actual human pee.

Can Magnum Synthetic Urine Be Reheated?

Yes, Magnum Synthetic Urine can be reheated; however, this will further reduce the reliability.

Does Magnum Synthetic Urine Work for Drug Tests?

No, Magnum Synthetic Urine doesn’t reliably work for drug tests as it can be easily picked up through lab testing as synthetic.

At what temperature will Magnum fail to perform?

Magnum fake urine will fail to perform at any temperature significantly above the average human body temperature of 98 Fahrenheit. Also, if the sample is heated and stored while it is still too hot, then the chemical structure can change, which would be picked up during testing.

Can Magnum be reheated? 

Yes, Magnum Synthetic Urine can be reheated, but you should avoid doing this more than a couple of times. The cooling and heating process can gradually evaporate water, which will increase the concentration of the chemicals. Heating the sample repeatedly will increase your chances of failing your drug test.

Is one of the items inside Magnum Detox’s box a temperature strip?

Yes, one of the items inside Magnum Detox’s box is a temperature strip, and you should make sure you know how to read it. Before you head into the test facility, make sure it’s at an optimum range to avoid failing. Microwave it for 10 to 15 seconds before attaching the heating pad on, and it should keep the temperature stable for a few hours.

How long does Magnum last?

Magnum lasts for a couple of weeks if you keep it fresh in a refrigerator. At the same time, you should always pay close attention to the use-by date to avoid ending up with a crappy sample.

Can body heat keep Magnum Detox warm?

Yes, body heat can keep Magnum Detox warm, and it is the recommended way to maintain a constant temperature before you enter the testing facility. The closer it is to the average human body temperature, the less likely it will be flagged as fake pee.

Can you chill Magnum Detox?

Yes, you can chill Magnum Detox to store it for a couple of weeks. You may not need the entire sample for a test, and if you have another test coming up within a couple of weeks, then storing it this way will work perfectly fine.

Can Magnum Detox be bought in stores?

Yes, Magnum Detox can be bought in stores, but it can be challenging to find. If your test is more than a couple of days away, then try to buy it directly from the makers to make sure you don’t end up with a fake.

Does Magnum Detox smell good?

No, Magnum Detox doesn’t smell good, but it’s the same as real human piss. The chemicals used in the synthetic product create this smell, and if it wasn’t there, then it could be a clear indicator that it’s a fake.

Our Honest Magnum Synthetic Urine Review

How Much Does It Cost? – Average

You’ll find that you can get a 4oz bottle of Magnum Detox for $39.95, which isn’t too high a price, but it’s more expensive than Sub Solution, which is the product I’d recommend.

Adulteration – Poor


There have been many Magnum Synthetic Urine review posts saying it did not work against the creatinine test, which is a huge indicator to anyone performing drug testing that the sample provided was fake urine.

The product expires really quickly. When it does, it will still look exactly the same as when you first bought it, but the creatinine levels will drop.

The only people that will be able to tell that it’s not good anymore are the lab techs who will end up telling you that your sample is fake urine.

Success Rate – Poor

There are tons of reports of users who have tried to use Magnum to get through a mandatory urine test for their job or for their military applications. Even when the Magnum Synthetic Urine instructions were followed exactly, negative results were sent back.

If you try to use Magnum in a situation where you really have to pass the drug test, there’s a small chance that it’ll work. But with other fake urine products on the market that clock a 99.98% success rate, it isn’t really worth the risk.

Our Conclusion

f grade

Does Magnum work? All in all, the brand is an unreliable product that has been shown to fail on a regular basis. It struggles to imitate clean pee even when you follow the Magnum Synthetic Urine instructions correctly.

It will show signs of being fake on a urine drug test, such as having the wrong temperature or insufficient creatinine, for example.

There are many Magnum Detox reviews that will echo the same opinion we have on this product.

With most work-related drug tests, you are only given one chance to pass it, so we always recommend the most effective and most popular product, which is Sub Solution.

One of the main advantages of using this product is it only takes a couple of seconds to heat up the sample, unlike most other fake pee products, which can take up to 30 minutes. Plus, more importantly, the users’ success rate is one of the best in the market.
