dsade is mostly right here. having been ex military, they will not test for gear, unless they suspect you are on gear. that means if you are in the marines, don't try setting a camp record for pull ups, if you are in the army, don't try 120+ push ups in 2 minutes, etc. don't give them a reason to test for it. if you hold a TOP SECRET clearance, take no chances with PH's - if there's a chance your judgement is less than ideal, they'll yank the clearance quicker than heck. if you hold a secret clearance or no clearance, don't worry about it. so long as you can buy it legally there's no problem with what it converts into - just make sure you got the bottle handy if they do specifically test for it. I would go to your EOC representative, and tell him your concerns just to be safe - regulations always change with the times.
