I have never been tested before so I do not know if they monitor or how they go about it but I am a low risk on probo for the first time ever. I told the guy at gnc everything I have posted and he said I should b in the clear but after failing the home test last night, I'm not too confident. I am going to drink the detox tonight and take another home test afterwards and see how that goes. Any other ideas? Thanks for the help so far
