Sub-Solution Synthetic Urine 2018 Review – Does It Really Work?

We all know that synthetic urine is pretty much the surest way of passing a drug test by mimicking real urine. The first of the next generation synthetic urine is the popular Sub-Solution synthetic urine. Being able to heat itself to a body temperature, Sub-Solution is what most illegal drug users use when it comes to urine drug test.

Here’s a review by a fellow stoner:

sub solution review
Sasa passed a job-related drug test in Avg 2016.

Sub-Solution is the new industry standard and has scored as the No. 1 synthetic urine for passing a drug test in 2018 synthetic urine review (it usually get’s a 5-star review by users). You should really check the story about the guy who also did a thorough research on the best synthetic urines and choose the Sub Solution – here is his post on 420magazine.

Basically all other synthetic urines out there are knockoffs of Sub Solution, but nobody has yet to master the self-heating property the Sub Solution has (you have to heat other synthetic urines to body temperature ‘somehow’ so they don’t catch you using synthetic urine in a urine drug test).

Not only does the Sub-Solution by TestNegative has the highest rating and self-heating mechanism, it is the only synthetic urine that has been around for more than 10 years. .That just tells you that people have been buying it for a long time and readily recommended it in order for the company to keep selling it – you can easily buy and ship it overnight here (they also have a 3+1 bonus option; just input ‘4’ in the ‘quantity’ box and you’ll get 1 for free – here is how to buy synthetic urine on sale).

The No. 1 synthetic urine in 2018 is Sub-Solution. You can buy it online here. Just make sure you order it before 4:30pm EST to get the same day shipping.

Let’s have a look at what some people who used Sub-Solution what they say about the experience:

Sub-Solution Reviews

What I found most credible about Sub-Solution synthetic urine is the list of ingredients that the solution consists of.

For example, on the packaging it clearly states that the powdered urine you get (with a vial for heating and plastic container) contains urea and uric acid. These are the two basic ingredients of urine that every synthetic urine should contain – but the Sub Solution is the only one that is clear about that.

I’m practically in love with it, so let’s look what others things about it:

What Do Users Say About Sub Solution Synthetic Urine?

Honestly having a closed door test is what you usually get when doing a urine drug test. Mixing up the Sub-Solution is a piece of cake when nobody is watching.

From this Sub-Solution review we also see that you can warm the solution up yourself is you tuck it up under your breast for an hour. However, the self-heating vial you get with the purchase, you don’t have to warm up for an hour. The vial warms it in seconds. That can be very useful when you’re in a cabin at Quest.

Is Sub-Solution A Life-Saver?

Well, it is for this guy. He has the truth of it though – all the guys on the street use synthetic urine and Sub Solution is pretty much the most widely known in the stoner’s world. 

Negative Review of Sub-Solution?

Whenever you have a popular product, you’ll have some negative reviews as well. Here is one about the Sub:

This is the same thing that was found in synthetic urine 2018 comparison. The Sub works like a charm but it is pricey. However, when trying to do a THC detox or pass a urine drug test in 24 hours with synthetic urine, you really shouldn’t be looking at pricing. Why?

Because if you buy a bad urine, your job is probably on the line. And a job is much more important than few extra $10 in the wallet.

Average Customer Rating is 4.4/5 Making Sub Solution Highest Rated Synthetic Urine

All in all, the Sub is the highest rated synthetic urine and it’s been around from 2003. It is sold exclusively online and we don’t list it where to buy synthetic urine in stores article.

When it comes to buying quality synthetic urine to pass a drug test, the Sub is the thing you get (if you can afford it).

Other synthetic urines might work just as fine (you’ll just have to heat them up somehow) and will cost a bit less but if you want to have a guaranteed ‘THC negative’ on your drug test, the Sub-Solution is the first choice.

You can buy the Sub here even a day before a drug test.

All the luck to you guys!

    I have a drug test coming up because it’s through a staffing agency uuugghhhh. I used Rapid Clear 3 times. It worked the first 2 times but not the last and the first one was for a USAF drug test lol
    I’m on the line between Sub-Solution and Quick Fix…..any recommendations would be helpful.

    • April 2, 2017 at 1:59 pm

      Since 2 out of 3 drug tests gave a negative result, I would presume you’re just near the cut-off rate and will pass without a problem within a week or so. If you have a drug test prior to that, in lets say 5 days or more, I would recommend good natural detox with drinking water, physical activity, lots of coffee and so on – maybe even a 3-day Toxin Rid detox to be perfectly sure you’ll pass.
      If you have less than 5 days, well, you can still detox and hope they don’t catch you but these staffing agencies like to be thorough and do proper drug testing, yeah uuuggghhhh is a good response. 🙂 In such a case, synthetic urine is a viable choice, I personally always use Sub-Solution because it heats itself up to body temperature. I heard people tried to use Quick Fix and heat it up but it’s impossible to nail down the body temperature. The Sub-Solution comes with a vial for heating it up and it tells you when it’s at body temperature, and thus nobody will suspect that you’re using synthetic urine. At least that’s from my experience, hope it helps. 🙂

    Just used sub solution for a labcorp test. Hoping it passes the test. Did not use the heating element but used hand warmers instead. The correct temperature was achieved. Does sub solution have a 100% pass rate? It’s all submitted now I just want a little peace of mind.

      If the temp is correct, it should work. Let us know about the results when you get them!

    I’ve already mixed the dried urine and water(didn’t make it to test site on time). Can I still use or am I S.O.L.?

    • August 31, 2017 at 12:04 pm

      The importance here is that both dried urine and water are sterile (without bacteria). Dried urine usually is, water less so. If there were bacteria in the water, they’ll multiply and urine will be stale – unusable.

    I just used this brand yesterday and followed all of the instructions stated in the box. I did have an issue with the temperature powder, but I was able to warm it between my legs to reach the right temperature. I was called today and told that I passed the 5 panel drug test! This really does work! It’s the first drug test that I’ve had to take and use a synthetic urine. I would definitely spend the money again on this product!

    • December 3, 2017 at 8:24 pm

      What issue did you have with temperature powder? I’m curious about how much to use? Can it get to hot? I plan on using room temperature water.

    • January 5, 2018 at 1:41 am

      What problem did you have with the temperature? Thx!

    I have a test on Tuesday. I just purchased sub-solutions. Hoping it will help me pass being I’ve never used synthetic urine. Whens the best time to mix everything? For example I’ll be going into the office Tuesday and will at some point be going to get a test during the day so it will be on the fly. Just wondering if you have any advice or words of wisdom for a first timer. Thanks.
