Out of all the detox products if one would work that would be my choice. They are the same people that make Quickfix synthetic urine. But its still just glorified dillution. Better off with the quickfix.
Urineluck has nothing to do with dilution.
Urineluck is an additive used to spike a urine sample. It actually comes in two vials which, according to the instructions, both must be added to the urine sample.
The downside is its use is not recommended for instant-type tests because it takes 90 min to fully destroy the drug metabolites in the sample.
Plus, additives are getting detected by the labs on a more frequent basis due to the increase use of pH, Chromate, and nitrite checks.

I do agree that subbing (synthetic or human) is a much better bet. If youre brave enough to sneak in an additive, then youre brave enough to sneak in a substituted sample.
