I made anavar caps the other day. They came out very good. I used the the pharmaceutical method of finding the ratio of the amount of filler needed to powder. Then I used geometric dilution with a mortar and pestle. For those that don't know geometric dillution is when you start out with x amount of powder powder then add an equal amount of filler (x grams) and mix in a mortar and pestle. Then take the total amount that you've mixed and add and equal amount again to the mortar and mix. You continue this until you mixed the entire batch.
