so I got my cottonseed oil today from AR to find out it isn't sterile. awesome!

My next shot is 2 hours ago. I still cannot walk from monday night's shot...literally. I have to perform tonight and tomorrow night and I need to be able to walk. I'm scared to shoot the ultra sust. Is it just the dumbest idea ever to mix it with the non-sterile oil? What can happen? what should I do?
