I received some primo and I think it may be fake. It was brought to my attention that if you can scratch the letters off it is actually test. I can scratch off the green letters with my finger nail and I can't scratch the blue dot off at all. It is lote L-066--810069, cad. sep. 05, I don't have a cam so I can't show pics. Sorry. It is by Schering. Can anyone help out?
