Does Magnum Detox Work?
Our Honest Review Of This Brand


This review was last updated in June 2019.

If you’ve ever frantically looked for synthetic urine because of a surprise test at work or you’re applying for a job with a new company, then Magnum 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 in actual function and reliability. And because Magnum Detox 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. 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 to come through the post. This is great if you're in a rush due to a surprise test and you have no other options left on the table.

Failed report

Like many other brands, Magnum (also known as Magnum Detox Novelty Urine) was designed to imitate baseline samples.

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

Magnum 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 Magnum Synthetic. Unfortunately, it does not work reliably enough for our liking.

You simply can't trust the effects of the Magnum Detox when it comes to most urine-based tests. After a thorough review, one of the main weaknesses with Magnum is, 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. 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 tests and often result in disastrous disappointment.

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

Instructions on How to Use Magnum Detox Urine:

  1. Shake the container before mixing and heating.
  2. Next, heat the fake 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 heating 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 cap and squeeze the contents out. At this point, the only thing left for you to do is to mix the pee with uric acid.

Please remember once you mix Magnum Detox 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 test even more.

Will Magnum Detox Actually Pass a Lab Test?

Overall, based on our review, Magnum Synthetic is too unreliable for it to be your number 1 choice.

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

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

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

A third issue that you should be aware of is that aside from inconsistent results, there is plenty of fake Magnum Detox 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 product.

Are there any Reported Cases of People Not Passing?

With any products that did not pass a urinalysis test, users will blame the product itself. 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 there are just too many reports online of failed tests. We have checked many different forums as well, and the overall tendency is that most testing facilities will identify it as synthetic. Check out the one below.

Basically, we're not too fond of the product especially if our whole lives are depending on it.

Our Honest 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 QuickFix, which is the product I'd recommend.

Adulteration - Poor


There have been many reports of Magnum posting results that did not work against the creatinine test, which is a huge indicator to anyone performing drug testing that the sample provided was fake.

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 invalid.

Success Rate - Poor

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

If you try to use Magnum in a situation where you really have to pass the test, there's a small chance that it'll work. But with other 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 which has been shown to fail on a regular basis. It struggles to imitate clean pee even when you follow the instructions correctly.

It will show signs of being fake, 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 Quick Fix.

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.

Make sure to read our review on Quick Fix Synthetic Urine, a much better alternative to Magnum.
