Such a relief to see your response bud, thank you... I have read nothing but good reviews on everythingurine, but I've had a tough time getting a hold of them lately. My question to them was about the "chemical" they use to preserve the urine while being shipped, is it detectable through these test? Also, can they tell that it's been frozen before and than thawed? It was a 5 panel drug screen I took at Labcorp. Thanks again for any more input that would be useful fellas, the waiting game really sucks, I hope it doesn't take too long to find out the good news! Anyone know that too, how long until Labcorp gets results back? Thx.
