Doesn't matter Twitched - Anavar (like all 17AA) is not absorbed in the gut, it's processed only by the liver, so before meals or after meals is irrelevant.
Personally, I take it first thing in the morning on an empty stomach - the full days dosage in the one hit. With a half life of around 9 hours it will taper off during the evening, thus minimizing the chances of HPTA downregulation. This was the preferred method of Dan Duchaine and (for me anyway) seems to work very well.
