You might fail a dilution test. Different places look at failing a dilution test differently. Some will view it as a failed test and others will let you take another one later. It can be a way to buy time though.
A good way to beat it is:
Get the 500 mg instant release pills.
I've also heard mixed things about cranberry pills. It acts as a mild diuretic so it makes you piss more. Idk if it actually helps to take it leading up to the test, but it can help if you take the day of the test because you piss more.
Drink a fuckton of water and eat a low fat and low calorie diet. Work out a bunch, but stop a few days before the test. Sit in a sauna. Basically do shit to burn fat and drink a shit ton of water.
