The identifiers have been worn some. It is a small white round pill. I'm in the United States. It looks as if the back side was quartered and the front side has a '10' in the middle and the wording around that '10' begins with either a 'G' or an 'O' (I believe it is the former) and the next two letters I can't make out and thing I see a "AR" the next two letters are either 2 t's or 2 i's or some combination thereof. And the last two are 'IN' -anyone know what this could be? It is about the same size pill as an oxy5.
