OC 10 pill fake or not

I had some OC 10 for the first time but I think they might have been fake but I'm not sure the markings are OC on one side then flip it over and it has 10 but it's sideways and when chewed one up it was hard and didn't taste like anything please let me know what you think.

The only way to know for sure if your oxy tablet is real or not is to have it lab tested. I'm closing this as we cannot give you an accurate answer.
