Schnick, just wanted to let you know that I just took a drug test last week through LabCorp. I was so stressed so I picked up a drink at the head shop down the street. I was all nervous because there were so many options of what brand. I asked all my friends as I have never had to take a test before and none of the brands sounded the same. I remembered my boyfriend had to take a hair follicle test last year and he used Test Pure shampoo. He came out negative for THC and had been smoking pretty frequently. I used the Test Pure Platinum and I got the call on Friday saying I passed. I took the test on Monday so I was REALLY thinking I failed b/c they told me they would call me in 24-48 hours. It worked though and I promised that if I passed I would get an account on here b/c no one had for sure answers. I had the same question too about taking a test on my period but you still have to.
