I purchased this little baby from a local smoke shop and followed the directions loosely (loose in that I ate whatever I felt instead of following the meal plan, otherwise I followed them to a 'T'). I came on here today and saw all these reviews saying that it didn't work so I went back down to my smoke shop and picked up an industry standard drug test. I passed.
Everyone's body is different but I'm thinking that either these other people did not follow the instructions as closely as they say they did or were, perhaps, around other smokers (something my clerk told me to avoid) and thus came into contact with the herb, but this is only speculation.
As for my record, I smoked every day for a little over a year before using this product and it worked in 7 days as advertised (which is great considering that it says NOWHERE that it cleans THC from your system).
My exercise consisted of drumming Emperor tunes, running, and biking. My diet was mainly healthy (as I've been wanting to improve on that anyways) but I also ate fast food and drank soda AFTER the daily regimen when I felt like it.
The home test I used was
Quicktest 3 Panel Urine Drug Test Kit (THC, COC, mAMP), which tests to 50ng/ml.
Also, this is the first review I've ever written because I've never cared enough about a product to spend the time to write one, but since this one allows me to make money, I think it's important people know that it's effective.
