Synthetic Urine (Fake Pee) — What It Is and When to Use It

Synthetic urine, often called fake pee, has been used for more than two decades in labs, universities, and controlled demonstrations to safely replicate the composition and behaviour of human urine. It’s designed for research, calibration, novelty, and educational use, never consumption or illegal activity.

At The Next Level, we stock reliable, lab-grade options for customers who want toxin-free, gender-neutral solutions that perform consistently while keeping safety and discretion front of mind.

What Is Synthetic Urine (“Fake Pee”)?

Fake pee is a laboratory-engineered liquid that mirrors the colour, odour, and chemistry of natural urine. Each formula includes:

• • Urea and uric acid
    
  • Creatinine and balanced pH
    
  • Proper specific gravity and foam behaviour
    

When warmed to about 36–37 °C (98–100 °F), it looks, feels, and reacts just like the real thing. These toxin-free formulas are suitable for any gender and safe for handling.

Temperature Control and Handling

Correct temperature is critical: human urine naturally exits the body near 37 °C. Too hot or too cold can create unrealistic readings.

• • Follow each product’s instructions carefully.
    
  • Do not microwave unless the packaging specifically instructs you to. Excess heat can form “hot spots” and lead to inconclusive results.
    
  • Use included heat pads and the temperature strip to check before use.
    
  • Some users gently shake the bottle to create a light froth — a small detail that can add realism.

Choosing What Feels Right

Many customers prefer synthetic urine because they feel confident and in control using it—especially compared to other masking methods. The right choice is whatever makes you most comfortable, whether that’s a simple flask or a hands-free belt system.

All products are safe, toxin-free, and suitable for any gender.

Best Practices for Safe and Realistic Use

• • Check temperature on the strip before use. Aim for 36–37 °C.
    
  • Avoid overheating — follow each product’s own heating instructions.
    
  • Store properly: Cool, dark place; unopened kits last up to a year.
    
  • Keep it clean: Wash refillable gear with mild soap and water.
    
  • Never ingest products. Use responsibly and follow all local laws.
