What is Monkey Flask by Serious Monkey Bizzness?

Monkey Flask is premixed synthetic urine from Serious Monkey Bizzness. The liquid is created and tested in a laboratory, and it resembles real human urine, even at a molecular level. The similarities between this product and real urine are the result of realistic ingredients.

It also has the same appearance and smell as urine, and it foams when you shake the bottle. This physical resemblance is crucial if you want to use the product for screenings, fetish play, or even pranks.

Our kit contains 3.5 oz bottle of synthetic urine in liquid form, an eight-hour organic heat pad, and a set of easy-to-follow instructions.

High-end synthetic pee cannot be detected with a surface inspection or even lab equipment. That’s what you must find – especially if you need the urine to pass a screening that can affect your career.

Serious Monkey Bizzness is a company that provides several such realistic, high-end, yet affordable products. These products include Monkey Urine, Monkey Whizz, and Monkey Flask. Many articles refer to all of these products as “Monkey Whizz,” but there are several differences between them.

How do You Use a Monkey Whizz Belt?

The Monkey Whizz belt is a urination device for simulating the action of urinating and filling a specimen cup discreetly.

This device includes a belt, a synthetic urine bag, and a tube that you can cut to an appropriate length. You can adjust the belt up to 54 inches to fit your waist. The bag has a temperature strip that indicates the current temperature of the content.

To use the Monkey Whizz belt, start by using the heat pad to heat the urine in the bag until it reaches 98 degrees to 100 degrees Fahrenheit. Then, fasten the belt around your waist, under your clothing, with the temperature strip touching your skin and the tube pointing toward the floor.

Wear the kit for one hour before use to ensure that the liquid reaches realistic body temperature. Before you fill the specimen cup, check the strip to ensure that it is between 95 degrees and

100 degrees Fahrenheit. Then, open the white clips and pour 2-3 ounces of synthetic urine into the specimen cup.

How Long is Monkey Flask Urine Good?

As explained in the instructions, Monkey Flask is good for up to 24 months, after which the chemical and physical properties will start changing, and you will no longer be able to use it for a urine screening, urine therapy, or self-administered urine tests.

You can, however, use expired Monkey Flask for pranks and diaper testing. According to some reviews from wildlife researchers and photographers, the expired Monkey Flask is also useful for repelling wild animals.

To ensure optimal quality and mitigate employment-related risks, be sure that you only use Monkey Flask that has not expired. You don’t have to refrigerate the liquid to extend its shelf life, but you should never expose it to direct sunlight or chemicals. The optimal storage setting is room temperature in a dark place, such as a drawer.

Does Monkey Flask Work?

Most synthetic urine products work quite well for fetish games, cleaning-agent testing, and pranks because these don’t have high technical requirements. But, clearly, the quality and realism characteristics of synthetic urine are significantly higher for applications including:

· Equipment calibration

· Urine screenings

· Development of life support systems

· Scientific research

· Urine therapy

· Novelty use

It might be hard to believe that a product called Monkey Flask from Serious Monkey Bizzness meets the chemical requirements of sophisticated laboratory applications, but it does. This is one of your most viable options for passing a screening or calibrating your equipment.

Serious Monkey Bizzness manufactures this product in a controlled lab setting and according to the highest possible standards. As a result, the only difference between real human urine and Monkey Flask that hasn’t expired is the method of production.

What is the Difference Between Monkey Flask and Quick Fix Urine?

Monkey Flask is similar to Quick Fix Synthetic Urine, in that both products comprise a premixed liquid in a container, with a temperature strip and a heat pad. Quick Fix and Monkey Flask both have a long shelf life at room temperature, and the preparation and delivery methods of these products are more or less the same.

But Quick Fix has a more complex formula than this and is more suitable for intense lab scrutiny. Monkey Flask carries a significantly lower price tag, though, and it’s ideal if you have budget restrictions.

The lower price tag doesn’t necessarily mean lower quality, though, and many labs prefer Monkey Flask by Serious Monkey Bizzness to Quick Fix to calibrate their urinalyses equipment. You also might not want to pay a premium for applications with lower requirements for chemical realism.

Can I Microwave the Flask to Speed Up the Heating Process?

If you have limited time to prepare your sample, heating the liquid to the appropriate temperature range might take too long if you are using a heating pad or just your body heat.

You can speed up the heating process by preheating the sample in the microwave for 5-10 seconds. Be careful, though. Heating it for any longer can increase the temperature to more than 100 degrees Fahrenheit, and you will have to let the liquid cool down to a realistic temperature.

Heating the sample once or twice with a microwave will not have any harmful effect on the liquid’s chemical properties. But if you microwave the Monkey Flask, say, once a week over a year, it might expire prematurely.

What Are Its Ingredients?

Monkey Flask contains all the ingredients of real human urine, including:

· Water

· Urea

· Uric Acid

· Chloride

· Creatinine

In addition to containing accurate urine ingredients, Monkey Flask also has a realistic pH range between 4.6 and 8, and it embodies the same density or “specific gravity” as real human urine. The density of normal urine ranges between 0.001 and 0.035.


Monkey Flask is synthetic urine that is easy to prepare and use, is affordable, and does an excellent job of mimicking the characteristics of real human urine. This product also has a relatively long shelf life, and you can use it for a wide range of applications.

What’s more, Monkey Flask is one of the most affordable Serious Monkey Bizzness products. However, it is just as effective for passing a urine screening as some of its most prominent competitors. If you need value for your money, a realistic product, or to pass screening, you can’t go wrong with this product.
