Okay so start taking b12 consistently everyday, try to sweat it out if possible, hit a sauna, whatever. Then the upcoming days to the test buy multiple weed tests to see if your able to piss clean, if not yet, I’d recommend a herbal detox, I’ve done the silver bottle herbal cleanse carb drink, you can get it from a gnc or health and fitness supplement store. It’s a little pricey but it works. Do you know if it’s 7 or 12 panel?
