To determine if a substance is a protein using the xanthoproteic test, you first need to add nitric acid to the substance. If a yellow color develops upon addition of nitric acid followed by a warming step, this indicates the presence of proteins. The yellow color is due to the formation of nitro derivatives of phenylalanine residues in proteins.
A single 2mg dose of Xanax will fully metabolize within 2 days on its own. The drug test is based on a ppm (parts per million) reading, which will be to low to be detected by standard non-spectrum testing after roughly 24 hours from ingestion. If you would like to play it extra safe the following vitamins can be purchased at your local GNC or drug store and will expedite the dilution of the benzoid. Vit C 50mg Thiamin 50mg Riboflavin 50mg Niacin 50mg Vit B-6 50mg Folic Acid 100mcg Vit B-12 50mcg Biotin 45mcg Pantothenic Acid 50mg Iodine 75mcg Magnesium 50mg Zinc 10mg Potassium 150mg Creatine Monohydrate 60mg Choline Bitartrate 25mg Inositol 25mg Para (Aminobenzoic Acid) (PABA) 25mg Mix aforementioned supplements with 1 gallon of tap water, shake and consume entire contents. Over the next 30 minutes refill the bottle and drink. Urinate frequently and avoid alcoholic beverages and unnecessary medications up to 24 hours before your test. Drink this mixture roughly 30 minutes before your test. When it comes time to fill the cup urinate into the toilet first for a moment, then fill the cup mid-stream. This is especially formulated for people with a large body mass and will eliminate the majority of substances (including THC) from your urine. (for marijuana this will work no earlier than 3 days after last exposure, for benzos and opiates it will work within 24 hours of exposure.) Hope this helps you all!
