ok i have a 50ml bottle of safflower oil from a company that will remain nameless. the label says 100% pure filtered safflower oil. does this mean it's sterile and can be used to cut down pain of test 400 injections? also it just has a rubber stopper not a crimp top. would it be better to transfer to sterile sealed vials. last thing if not sterile how would i go about doing that. wondering because b12 doesn't mix that well. thanx
