Has anyone on this forum tried making their own injectable methylcobalamin from pure powder? The pure powder can be ordered from China. With sterile lab technique and darkroom conditions, it seem like it would be fairly easy to make. I know that Fredd's protocol calls for the sublinguals. This is due to the inconsistent quality among the compounded MB12 injections. Still, I do best with the injections. I'd like to try making MB12 25 mg/ml solution myself and would greatly appreciate hearing from anyone with experience doing something like this.
