I do the drug testing for our company and called the vendor who assists us, and asked about testing for steriods. He said that there is a screening test that will tell u if someone is on AS, this screening test is quick and cheap, it WILL NOT tell u which AS just that u have taken AS....the second test is used to confirm which type of AS and the levels in the blood, this test is quite expensive. He also said it that there are not many MRO's (medical review officers) that can do positive reviews....
