I'm traveling by air (within the US) for 7 days and am on a 4 day cycle. My test and deca is by prescription (so no legal problems), but is unknown by my wife. Does the metal tops of vials and syringe (only need one) get pickup up by x-ray for carry on or should I pack it on checked luggage? I don't want some overzealous TSA finding it in my checked bag and then questioning me in front of my wife. Sugestions?
