About Upass
What are the uses for Upass?
Upass fake urine is made for jobs where a consistent, realistic sample matters:
- Clinical laboratory testing: a control and reference standard for calibrating diagnostic equipment and urinalysis machines.
- Research and development: a stable substitute for human urine in biochemical, pharmaceutical, and product testing.
- Education and training: hands-on urinalysis practice for medical students, lab trainees, and instructors.
- Adult sensory play: a sterile, sanitary alternative that looks and behaves like the real thing.
What is Upass Synthetic Urine?
Upass is a scientifically formulated synthetic urine (fake pee) that replicates the chemical composition, pH balance, and specific gravity of natural urine. Safeguard Labs has made it since 2009, it is independently lab tested, and every batch is quality-checked in-house before it ships.
What comes in the Upass kit?
Every standard Upass kit includes the same four things:
- A premixed 3 oz bottle with the Upass logo embossed in the plastic (no powder, no mixing)
- 2 Hot Sacks air-activated hand warmers
- An adhesive temperature strip
- A dispensing cap and rubber band
How do I use Upass?
Four steps, start to finish:
- Shake the bottle so the contents are well mixed.
- Microwave for 5 seconds. If it needs more, add 2 seconds at a time. Never exceed 10 seconds total: overheating causes temperature problems.
- Check the temperature strip. You want a reading between 90°F and 100°F. No reading means the sample is too hot or too cold, so adjust in small increments.
- Attach the hand warmers to the bottle to hold the temperature until you need it.

Temperature, Storage, and Shelf Life
How do I store Upass for later use?
Storage takes zero prep. Three rules:
- Keep the bottle tightly closed to prevent contamination.
- Store it in a cool, dry place away from direct sunlight.
- It stays good up to the expiration date printed on the box.
Can I reuse Upass after heating?
Yes. Reheating synthetic urine is normal: Upass can be reheated multiple times if needed. Heat it, let it cool, heat it again another day. Just check the temperature strip before each use.
Does Upass expire?
Yes. Sealed bottles carry a 2-year shelf life when stored properly, and the expiration date is printed on the bottom of every box, next to the lot number.
How long is synthetic urine good for?
People ask this a dozen ways: does fake pee expire, can synthetic urine go bad, how long does fake urine last. The honest answer is that every synthetic urine has a shelf life. For Upass it is 2 years sealed, with the exact expiration date printed on the box, so you never have to guess. A quality kit stored cool and dry stays good right up to that date.
How do I heat Upass without a microwave?
No microwave needed. Every kit includes 2 air-activated hand warmers, and they can do the whole job:
- Shake a hand warmer to activate it, then hold or strap it against the bottle.
- It brings the bottle into the 90°F to 100°F range in roughly 45 to 60 minutes. Confirm on the temperature strip.
- Keep the warmer secured and it holds that range for up to 8 hours.
The microwave is just the shortcut (5 seconds, then the hand warmer holds it). Both methods are covered step by step in the official instructions.
How do I read the temperature strip?
The adhesive strip on the bottle shows the temperature at a glance:
- A ready sample shows a reading between 90°F and 100°F.
- No reading at all means the sample is outside that range, either too hot or too cold. Warm it or cool it in small steps until a number appears.
How do I know if Upass is at the right temperature?
The strip shows a number. It should read between 90°F and 100°F. If it is blank:
- Too hot: let the bottle sit until a reading appears.
- Too cool: reheat in 2-second bursts and check again.
- Keep the hand warmers attached to hold it in range once it is there.
How long does Upass stay warm?
Keeping synthetic urine warm is what the included hand warmers are for. Heated and kept with them in place, Upass holds the correct temperature range for up to 8 hours; on its own, the bottle cools below range in about an hour. Every kit includes 2 warmers, so you have heat to spare. Confirm on the temperature strip right before use.
What happens if I overheat Upass?
Nothing is ruined. A blank strip is not a temperature strip that stopped working; it just means the bottle is out of range. Cool it down the right way:
- Let the bottle cool at room temperature until the strip shows a reading again.
- Never use the freezer or cold water to speed it up. Shock cooling can make the temperature strip malfunction for real.
- Once it reads 90°F to 100°F, keep the hand warmers attached to hold it there.
The Brand, The Store, The Real Thing
Does Upass work?
Upass is designed to replicate natural urine on the measures a standard urinalysis reads: balanced pH, realistic specific gravity, and organic markers including creatinine, urea, and uric acid. It is independently lab tested, every batch is quality-checked in-house, and Safeguard Labs has sold millions of kits over 17+ years. The full breakdown of what our testing covers is at Does Upass work? Reviews and batch testing.
What is Upass made of?
Upass is a premixed solution with balanced pH, realistic specific gravity, and organic markers including creatinine, urea, and uric acid, the same measures a lab reads in natural urine. The exact formulation is proprietary and stays in-house; it is what 17+ years of continuous production is built on.
Where can I buy Upass?
Upass is sold nationwide at authorized retailers, but not on Amazon or at Walmart. Online, upassurine.com is the only authorized store. Ordering here means current-batch stock, and orders by 3:00 PM PT Monday to Friday ship the same business day. More detail: Where to buy real Upass.
Is it Upass, U Pass, or You Pass?
The brand is Upass, one word, made by Safeguard Labs. Searches for u pass, u-pass, you pass, and youpass all refer to the same synthetic urine kit; the spelling on the box is Upass. It is not related to transit passes or software products with similar names. Whichever way you spell it, the authorized online store is upassurine.com.
Is Upass pee the same thing as Upass urine?
Yes. Upass pee, Upass urine, and Upass synthetic urine all refer to the same Safeguard Labs product: Upass premixed synthetic urine. U Pass, UPass, and You Pass are common misspellings, not different products. One brand, one manufacturer, in continuous production for over 17 years. You can order the 3 oz kit here.
What does a genuine Upass kit look like?
Every genuine Upass bottle has the Upass logo embossed in the plastic, and every standard kit includes two Hot Sacks branded hand warmers. The box is printed with a lot number and expiration date next to the UPC, so a box with no lot number is not ours. Treat these as a quick look rather than proof. Online, upassurine.com is the only authorized store. Upass is also sold nationwide at authorized retailers, but not on Amazon or at Walmart.
When does a Upass order ship?
In stock. Orders placed by 3:00 PM PT Monday to Friday ship the same business day.
