"Sterile Oil" from chem sites?

[iron irish]

Does anyone know if the oils from the chem sites are actually "sterile" already or do they need to go through a whtman filter as well.Also if the are sterile already,are they in multidose vials.Wanna use the oil to cut some very painful but potent UG gear and I was hoping to do the mixing one shot at a time in the syringe.

I have had no sterility issues. Just make sure you order from a reputable place. If you're paranoid, filter through a Whatman and bake at 200degrees F for 30 min.

Yes, it comes in a multi-use bottle, sealed with a rubber stopper.
