B12 injection or liquid drops

I've been mixing oil and water for years with no issues. Bubbling? You can inject bubbles with oil, too. No problem at all. Sterile is sterile.

A few bubbles im won't hurt you.

I believe that reference wasn't to air, but rather the way the oil and water mix. You can see visible, contained bubbles of the water-based substance inside of the oil (visually it looks like polka-dots). Again, I'm not concerned with his warning, as I inject the compounds mixed together quite regularly.
