This product is legit. I had to submit a drug test for pre employment so I quit intake immediately. I had two weeks clean by the time I gave my sample, it states that you only need to eliminate toxin intake for 48 hours before using, so I certainly did not test that theory. But trust me, this must have still worked, because I needed more than two weeks even though I was very adamant about trying to flush my system by my lonesome( drinking copious amounts of water, cranberry, green tea, ect.) I followed simple directions, read a lot of these reviews and all I could about product before buying and using. But I promised to myself that if I got the job, I would write a review on how this saved my butt. And here I am, thank you green fleets. I actually ended up taking on the wrong day, when I was misinformed of when test would be, and had to buy it twice. Gotta spend money to make money. But with that being said you tell me if I think it was worth it... t was a success.
