I caled my best friend who is a lawyer and he refferd me to my boat captians friends in FL. They told me to Sub get a product called Your in Luck
"Your in Luck" (t/n UrineLuck) is not substituted urine. UrineLuck is a drop-in additive thats used to spike a urine sample. The U/L additive will not work if youre taking an instant-type test because it takes 90 minutes to destroy all of the drug metabolites in the urine sample.
In addition, additives are being detected by labs on a more frequent basis than before. The sample gets flagged as 'adulterated' when the pH, nitrite, and chromate levels are abnormal.

The Quick Fix synthetic is a better bet. It will pass all types of drug tests, including the instant tests and the top gun GC/MS. And as long as you have a current batch, the QF will pass all of the integrity checks as well.

If youre brave enough to sneak in an additive, then youre brave enough to sneak in a substituted sample. Its much easier to pour the sub sample in the collection cup instead of holding the cup in one hand and fumbling around with 2 additive vials in the other hand (The U/L additive comes in two vials which, according to the directions, both must be added to the urine sample).
