CleanUrin is a completely synthetic urine substitute that replicates the chemical profile of freshly voided urine from a healthy, sober person. It comes in a 25ml sachet, ready to use without any mixing, heating, or preparation. The formula passes almost all common laboratory screening methods, returning normal values for pH, creatinine, specific gravity, and other standard urinalysis parameters — and it even fluoresces under UV light, just like the real thing.
Synthetic urine with consistent, known values is a practical tool. Lab technicians use products like CleanUrin to calibrate urinalysis equipment, ensuring machines return accurate readings before processing actual samples. The formula is engineered to hit the expected ranges: a pH between 4.5 and 8.5, creatinine levels within normal bounds, and a specific gravity that matches human output. That consistency is exactly what calibration demands — no dietary fluctuations, no hydration variables, just a reliable baseline every time.
Each sachet ships with one of three colour-coded identification marks: green, yellow, or red. These indicate slight variations in values like pH and creatinine, mimicking the natural fluctuations you'd see in real urine depending on diet and hydration. All three colours meet the same standard of quality and are equally suitable for use. You don't need to choose — whichever you receive works.
And yes, the UV-reactive proteins open up some creative possibilities. The manufacturer themselves acknowledge the prank potential. We'll leave that to your imagination.
| Spec | Value |

| Composition | Fully synthetic — no human or animal urine |
| Parameters replicated | pH, creatinine, specific gravity, colour, UV fluorescence |
| UV reactivity | Yes — contains proteins visible under UV light |
| Colour codes | Green, yellow, or red (random — all equivalent quality) |
| Preparation required | None — use directly from sachet |
| Sachet material | Sturdy, pliant, silent-opening design |
| SKU | SM0251 |
We've handled a fair few of these over the years. The sachet is genuinely well-designed — it's flat, flexible, and sits comfortably against the body. You could tuck it into a waistband, a pocket, or even wear it during a run without noticing it's there. The opening mechanism is the standout detail: it tears cleanly and quietly, even with damp or sweaty fingers. No fumbling, no loud ripping sounds. For a 25ml pouch, the engineering is surprisingly thoughtful.
The one honest limitation: 25ml is a single use. One sachet, one application. If you need multiple uses — say, for calibrating equipment across several test runs — you'll need to pick up more than one. There's no resealing this once it's open.
One thing worth noting: CleanUrin is supplied at ambient temperature. If your specific application requires body-temperature urine (around 36–37°C), you'll need to warm it beforehand. Tucking the sealed sachet against your body for 30–60 minutes before use is the simplest approach — body heat does the work. Some users report that this timeframe is sufficient to bring the contents within the expected thermal range for standard testing equipment.
If you're after a complete kit rather than just the sachet, look into the CleanUrin Set 2.0, which includes accessories for temperature maintenance and more discreet delivery. For general detox support ahead of a screening window, browse our drug test category for complementary products.
We've sold CleanUrin from the shop since the early days, and the questions tend to cluster around the same few topics. The most common: "Does it actually work?" The short answer is that it's formulated to return normal values on standard immunoassay panels — the kind used in most routine screenings. It replicates pH (typically 5.0–7.0 range), creatinine (above the 20mg/dL threshold that flags dilution), and specific gravity (1.003–1.030). These are the parameters that basic dip-stick and automated analysers check first.
The second most common question: "What about the colour codes?" The green, yellow, and red markings aren't quality tiers. They represent natural-looking variation in the values — the same way your own output would differ after a coffee-heavy morning versus a water-heavy afternoon. All three pass the same tests. You don't get to choose which colour you receive, and you don't need to.
Third question, asked more quietly: "Can I use it for pranks?" The manufacturer explicitly mentions this as a use case. The UV-reactive proteins mean it shows up under blacklight just like the real thing. We'll say no more.
The synthetic urine market has a few players, and they're not all equal. CleanUrin distinguishes itself on a few practical points. The sachet format is more discreet than bottled alternatives — no rigid container, no cap to fumble with. The silent-tear opening is a genuine advantage over screw-top or snap-cap designs. And the inclusion of UV-reactive proteins is a detail that cheaper formulas skip entirely, which can be a problem if the testing facility uses a blacklight check.
Where CleanUrin sits in the middle ground: it doesn't come with a heating element or temperature strip. The CleanUrin Set 2.0 (sold separately) bundles those accessories together. If temperature control matters for your use case, the full kit is the better buy. The standalone sachet is best for situations where you're handling temperature yourself or where ambient-temperature urine is acceptable — equipment calibration, for instance.

No. CleanUrin is 100% synthetic. It contains no human or animal biological material. The formula is engineered from scratch to replicate the chemical markers — pH, creatinine, specific gravity, and UV-reactive proteins — found in real human urine.
They indicate slight variations in values like pH and creatinine, designed to mimic the natural fluctuations caused by diet and hydration. All three colours meet the same quality standard. You receive one at random, and all are equally effective.
Roughly 30–60 minutes when held against the body. The sachet's thin, pliant material transfers heat efficiently. If you need precise temperature control, consider the CleanUrin Set 2.0, which includes a heating pad and temperature strip.
No. The sachet is single-use. Once torn open, it cannot be resealed. Each 25ml sachet is designed for one application. Stock up if you need multiple uses.
Yes. The formula includes proteins that fluoresce under ultraviolet light, exactly as real human urine does. This is a detail that cheaper synthetic alternatives often lack, and it matters for any scenario involving a blacklight verification step.
Keep the sealed sachet at room temperature, away from direct sunlight and extreme heat. There's no need to refrigerate it. Check the packaging for the expiry date — the synthetic formula has a shelf life, and expired product may not return accurate values.
Yes. Standard urinalysis panels require a minimum sample of around 30–45ml, but many routine dip-stick tests work with as little as 15–20ml. The 25ml sachet covers most standard testing scenarios. For panels requiring a larger volume, you may need two sachets.
