I got a pretty decent sized white round tablet that is said to be oxycontin but I dont think it is. Oxycontins are usually smaller and say OC on one side and list the milligrams on the other side. This one says RDY 344 in a circle on one side and then has a slash/score going across it on the other side. I dont think this is oxycontin, can anybody tell me what this is?
