When searching online, I found a website that sales Validity (Adulteration)Test strips and it says this less then $2 strip can detect Pyridinium chlorochromate used in synthetic urine.

it reads... Pyridinium chlorochromate (sold under the brand name "UrineLuck") is a commonly used adulterant.
You got things all mixed up there.

UrineLuck is a brand name for a drop-in additive used to spike a urine sample. Quick Fix is the synthetic urine. Both products are made by Spectrum Labs.

Also, additives are classified as adulterants. Synthetic urines are classified as Urine substitutes.
