i fought mma for aabout 4 years. in the amateur ranks(small shows) they do not test for aas. as soon as you start getting paid, turn pro, or fight for a belt, they start testing for aas. i was tested after fights, never before. they wated up till two weeks after, and as littlea as the next day. i have known alot of people to use fake bladders to beat the testing., it is a common thing in mma. hope this helps some.
