I may be wrong, but I think Liquidex is always taken orally bro. At least that is how I use it. I realize most of it comes in a container with a rubber stopper and is drawn out with a
syringe, but I am pretty sure its always taken orally. I haven't used every kind of liquidex on the market, but what I have used is only taken orally according to the directions. Someone else might know more about the other brands though. Later
