Drop-in additives like the Urineluck wont work on instant-type tests because it takes 90 min to destroy the drug metabolites in the urine sample.
Plus, labs are detecting additives more frequently than ever before. They are detected when the sample gets flagged for excessive nitrites, high chromates, and/or an abnormal pH.

Subbing with the Quick Fix synthetic urine (made by Spectrum Labs, who also makes the Urineluck additive) would be a better bet. If youre brave enough to sneak in an additive, then youre brave enough to sneak in some synthetic urine for a sub. Its actually more easier to sub than fumbling around with additive vials in the bathroom stall.
