Hey everyone. Tomorrow, I'm due for a pre screen unregulated drug test and I'm wondering if anyone here has used Quick Fix 6.1 Batch number ST153C46U successfully before? I haven't been able to find anything online on that specific batch number. The test is being done at Concentra in Cincinnati, OH. Anyone on here successfully pass a drug screen with QF 6.1 at Concentra in Ohio? Any help would be great, I'm nervous as hell because I have never used a synthetic sub before.
