Holy crap, Sub-'s on AM?!?!? HA!! :lol:
If I were you, I would definitely stear clear of it. There are many PH's out there now that convert to something or other that could give a false positive on a 'roid test. 3-AD does convert to stanalone, which, I'm pretty sure, would trigger some negative attention.
Keep in mind that you are not taking a steroid here, and that may be something that you'd want to explain to your superiors before taking any particular substance. It isn't that you are taking anything directly; moreover, you are taking something that will convert into a "triggerable" compound.
When in doubt, check it out.
