Apart from working out and sweating you need to change your diet up and detox, no need to buy expensive shyt since you looking for a job.
Just simple shyt like green tea with honey or agave ,
And consuming tumeric, ginger, flaxseeds , cutting down on sugars, carbohydrates and processed foods will help you out a lot.
On my personal experience green tea and and flaxseeds detoxes me right out. I am a heavy smoker just bud and homemade edibles I don't fukk with extracts or hash and it takes me about 14-21 days to be fully clean. But it depends on how fat I am at the time
buy test strips and test your self every week. Again take the advice you see here and try a combination of different things everybody is different.
If its just an urine test you can beat it with Niacin or multivitamin, drinking loads of water and taking 10 grams of creatine but you have to know your body and how long it takes it to digest the pill so your piss would have color. The creatine fools the test so it doesn't know you watered down your urine and the niacin and multi vitamin will give it color
I passed a test once with 3 days notice and took too many megamen vitamin from GNC shyt had muy urine looking like anti-freeze tech looked at it like
but I passed
Also this is important cut off soft drinks them empty calories love to bind fat to your system.
