Did what I wanted to do. I suspected that a certain item purchased somewhere wasnt legitimate. I was correct, but the kit proved me right. The only thing I didn't get was at the end of the test there's a section with the label BUP this was shoeing up as either nearly negative or trace amounts. At first thought BUP id think bupernprphrine but why anything would be cut with that is a mystery to me. Either way test works and if your unsure about what's in the stuff that going into your body then this is for you. Considering the name of the site you all know what I mean.
