I'll answer your question if you want. I just passed a pre-employment screening using an detox drink that I purchased instead of N2's recipe, even though I was well aware of the fact that I was just diluting. I did this for safety and ease of use. I've never done any diluting before, and honestly, I didn't trust myself to not fuck it up. I figured that these potions, while obviously over-priced, already include the vitamins etc. needed to hide the fact that I was diluting. So while N2's recipe is cheaper, personally, I was more comfortable with the product I purchased than some DIY home method.
