There are certain legal drugs/supplements you can take that can cause a false positive on certain drug tests, depending on what they're testing for. IIRC, eating a poppy-seed muffin could give a false positive on a heroin test. Don't worry though, I've never heard anything about male-enhancement pills causing false-positives.
Sorry to hear about your small johnson, by the way.
