You need about 3 dollars.
Goto your local store and ask a person if they can show you where SureGel is. Make sure its not fruit kind(Its a yellow box like pudding) Buy it
Then like 1hr before you take a piss test mix all the powder with a lot of water.
Put it in the mircowave for about 30 seconds.
Stir it so theres no chunks in it or you will gag.
Drink it all at once.
After you drink it you gota piss 2 times. Then the 3rd piss is the one for the piss test.
After you drink the SureGel DO NOT DRINK ANYTHING WITH SUGAR IN IT! or you will fail
Your piss will come up scott free.
(You will know if it worked when your piss is a clear whitish color)
