HEY, one thing I am actually knowledgeable about, LOL!
As a general rule of thumb, all of those crazy oddball theories using specific items are hit or miss. These tests are designed and honed over the years to weed out (sorry) the balogna.
First and foremost, DO NOT USE DETOX KITS OR MASKING AGENTS! THEY ARE ALL LIES. With the exception of detox mouthwash. That stuff actually works. But that is actually the only kind. If detox kits other than the mouthwash worked for other people... they quite simply did not have as much in their system as they thought to begin with.
You basically have two options... dilution or substitution.
If you have the money to spend and don't want to sweat it, just go with substitution. With a little practice it is actually pretty easy. DO NOT USE SOMEONE ELSE'S URINE! If you leave it room temperature for a couple days, it will start to stink super bad and lose its regular color, and you will heat it up and make it smell worse, and it will be a gross, awkward way to not get the job. All you need to do is buy this product called monkey-whizz. Note: I do not work for monkey-whizz. It is just, in my and friends experiences, the most reliable and effortless way to beat the test. On the bottle that you strap to your junk, there is a temperature slip that shows you, as you urinate confidently into the cup, if your pee is the right temperature, so there is no doubt in your mind. Your pee must be within 90-100 degrees farenheit, and they test the temperature right there immediately after you give them your sample to make sure it's legit. Monkey-whizz comes with special handwarmers that get your fake piss to exactly the right temp. You might consider having a practice run at home over a toilet in preparation. You don't have to use hardly any of the fake piss and you can always order extra handwarmers from their site. If you are worried about making sketchy noises, piss into the cup like you are actually supposed to do, and as you empty the rest of your bladder into the toilet, piss directly into the water for maximum loudness and dump the urine in the cup, into the side of the toilet. Fill cup with monkey whizz. KAPOW! youre good to go.
Your other option is dilution, which is a bit riskier. It is not foolproof by any means. It has so many variables that it is hard to say what will work for whom. Things such as body weight/fat/BMI, metabolism, age, amount of excercise, amount of food intake, how much water you drink, and, of course, how much you blaze. If you plan on going the dilution route, don't even consider it unless you have been clean for 7 days (and really 10 would be better.) Any less than 7 and you are at serious risk for failure. What you want to do is eat very little sodium the first 5 days. You also need to avoid fatty, greasy foods. You also need to drink lots of diuretics (coffee and cranberry juice), LOTS of water, and get LOTS of excercise. In combination with this, take 1 or 2 niacin a day. What we are trying to do here is to basically get as much out, as fast as we can. 2 days before the test, start loading up on creatine supplements. THIS IS PERHAPS THE MOST IMPORTANT PART. They test for the specific gravity and also creatinine levels in your urine to ensure that it isn't diluted. Creatine metabolizes into creatinine in your body, but it takes a day or two. So starting 2 or 3 days before the test, every day leading up to the test, make sure you are taking a GOOD amount of creatine. You can look up specific levels online that will make more sense for your BMI. Anyays, the day before the test, return to normal fluid intake. Quit excercising. Start eating a whole bunch of fatty and salty foods. No coffee, cranberry juice, or niacin. We want to put the body back into fat storing mode and quit excreting those metabolites at such a fast rate. Now, the day of the test, wake up early and start freaking CHUGGING water. But not too much. YOU CAN DIE FROM DRINKING TOO MUCH WATER. I REPEAT, YOU CAN DIE FROM DRINKING TOO MUCH WATER. Drinking about 32 fluid ounces of water every 30-45 minutes should be sufficient. Just do what feels right. Dont drink so much water that you feel like you are damaging yourself, but remember, you are trying to DILUTE your urine enough to fool a drug test that detects extremely small levels of metabolites. Don't be too shy or it will end in failure. Make sure get about 8 voids (urinations) in before your test if its in the afternoon. If it's in the morning (which a lot are, because the first few voids of the day contain way more metabolites for you to fail from), just aim for 4. Don't want to pee much more than that, or it might read diluted, even with your altered creatinine readings. While you are chugging all this water, take a whole bunch of vitamin b-complex pills to turn your pee an acceptable color and to help very slightly with the specific gravity of the urine. When it is time to urinate, ONLY USE THE MID STREAM! It is proven that the middle of the stream (as in, not the beginning OR the end) has by a significant amount, less metabolites in it. So piss in the bowl about halfway, fill your sample, and finish it out in the bowl.
THIS IS FOR MARIJUANA ONLY.
I wish you luck, brothermane.
Once in a while, you get shown the light in the strangest of places if you look at it right.
