This is where I bought mine and passed My test 5 days later. The only problem is it's $27.00 + shipping. Make sure it's 4.0.

You will also see Ace-It Synthetic Urine below it for a few dollars cheaper. I bought both and I tested both with THC test strips and they both passed the test but I keep the cheaper one for emergency unannounced tests.

Good Luck....:thumbsup:
