Like many have said; unless you've got an airtight explanation you should just plan for your post-sanction future. That and find out who had an interest in seeing you test positive, if anyone.
Rule 1:Basically don't get injected with anything unless you're getting surgically repaired. Rule 2: Don't take vitamins and reserve injesting supplements to main stream stuff everyone else uses like Gatorade. I'm also not a pro trying to train or recover from weeks of GC racing or I'd have my own folks looking out for everything that comes in contact with me while still trying to adhere to Rules 1 & 2 (presumably I'm big time enough to afford that).
If you're a low-budget pro you probably haven't attracted enough attention to get a tainted report.
