They are banned both in and out of competition. The AAF from a tested sample will incur the normal sanction, ie a ban of two years for a first offense. However, the idiots that run the show decided that only "in competition" samples would be tested for this drug and samples taken OOC are not tested for it. Therefore, whilst a TUE should be generated for OOC use, nobody bothers because they know that an AAF will never be generated. This modification to the testing protocol was introduced about 6 years ago. So you have a nice little pact - "we wont look and don't you tell us that you are using it." Therefore, only somebody who believes in Santa would think that although the TUE was only for one injection, that was the limit of the dose applied.
