okay so i had a drug test at labcorp today for pre-employment. if i pissed i would have failed. i used my friends clean piss. i put it in an old axe lil shampoo bottle. i washed it out with hotttt water and sit it upside down to drain. i waited till it dried stuck my finger in there completely clean and dry. i put clean piss in the bottle. i kept it on my body all night to stay body temp. i checkd it this morning and it had bubbles a tthe top. that night before it didnt. i poored the bubbles out and it was good. about 4 hours later i went to poor it in the piss cup and it bubbled a little. does that mean oxygen bubbles were popping up for being in there and shakin up. or was there a little shampoo left? and im curious if it was shampoo it was very little. with that being in the piss cup. would it make me fail??? pleaseeee help!!
