Our Formula: Science Meets Precision

What sets our synthetic urine apart is our uncompromising focus on scientific accuracy. Designed using advanced technology and developed in collaboration with Spectrum’s patented formulation expertise, our product is engineered to closely replicate the natural characteristics of real human urine.

From pH balance and specific gravity to protein content and appearance, each batch is carefully crafted to achieve consistent laboratory-grade realism. The subtle coloration, slight haze, and natural foaming effect all reflect our meticulous attention to detail—creating a product virtually indistinguishable from the real thing.
