I would like to know if there are any OTR diet pills that are effective yet will not show up on a full screen urine test.

Sure. Duct tape over the oral cavity works wonders. Everything else shows up.

It does not surprise me you would say something like that although I was serious.

Yes, and I am serious as well. I did take your question seriously and yes, there are no OTC's that would not show up.

Thank you for your input but I tested one myself and it did not show up, Slimquick Extreme, although it was an OTR test also it tested for Amphetemines (sp). Also my friend tested Diet Fuel and it did not show up either. I guess it just depends on what you take. Thanks anyway!!
