Penetrate is topical --- you don't eat it!
The general idea is to load a power into it. I'm about to give it a try ... there ain't instructions with it. Not sure whether to dissolve in water or alcohol then add to the TD.
Whether it works is another matter. I seem particularly sensative to TD so it makes sense.
The idea behind TD is to get about the bioavailability problem that the liver generates by smashing things to pieces. I guess my liver is overly efficient.
