Yes it works. You only need 1 bottle. If the lab tech says they need more than 60 cc's they are messing with you. If you came out of the bathroom with a 60 cc sample they have to accept 60 cc's. Some techs know about quick fix and will try to scare people by asking for more but they have to accept a 60 cc sample. A split sample (two vials of urine an A and B sample) only requires 30 and 15 cc. They can do two 30 cc samples if they chose to but no more. This is from a person who owns a collection site.
FakeBoobsRule Reviewed by FakeBoobsRule on . Just used QF 4.0 @ Labcorp Just came from taking my test at LabCorp, of course I was nervous as hell when I went in. I got there, they made me wait about 15 mins before I went into the lab. Once I got in the lab they made me fill out some paperwork, then the collector walked me into the bathroom;told me I had 4 minutes and then left. There was no supervision and I was able to lock the door. Once he left, I went to work like MacGyver. :) Please take TWO bottles with you when you go. YOU WILL NEED THEM BOTH. Rating: 5
