I pass monthly piss tests for my job using a cleansing product from a local smoke shop called "xpulsion by herbal essence". It's the only one ive tried, but i'm pretty sure the ones you get at CVS work as well. There wouldn't be a market there if no one was getting results.Never heard of this product you are speaking of. Only thing I know is all of the Products for beating a Urine test are basically a scam. I have never heard of anything for a blood test at all.
I used a synthetic urine called "quick fix 4.0" i've used it twice successfully, and so have a few friends, also all the reviews on the internet are mostly positive, it's 20 bucks, sold where ever pipes and bongs are sold
