i don't wanna pop any bubbles but....you're not going to "fake out"ANY drug test....if you alter your body's chemistry,they will know...its called "masking".....you need an exact number of electrolytes in your body,and when you "flush"you alter this number...you say you are158lb....how tall?if you're 158 at 5 feet tall you're fat,and thats where the THC will reside most...if you're 158lb and you're 6 feet tall,you'll "clear" out faster....don't count on those market "flushes" and "tests" to be accurate....i have NEVER heard of ANYONE using these and pass anything...worst case scenario...wait a month(most employers have a "cutoff"line...say...50/ppm)...but i guarentee you will STILL test positive...unless you're an occasional smoker,but you're not,still positive after 2 months(53 days)puts you in the dinner and a bong crowd...just like me...lol
