I dont care what anyone tells you however, i will tell u my PERSONAL experien ce. I have used that spacific manuacturers products for over 8 years and they work fine. I take a fedral UA and pass every time. I follow manufaturers directions to a T every time.

I have read up that tested is spacific gravity is checked and if it is not within range your test will come back as "negative dilluted" and you will have to test again. I recomend skiping the dope for 24-48 hours prior to the test.. DONT drink a shit load of water. Just drink as u normaly do and then take the product 1-2 hours prior to the test, refil the bottle once and drink it. U will be fine. imp:
