I can't help but wonder why you are asking this. Biotest uses Anavar extensively as an example in their advertisments for Carbolin-19. They constantly point out that in lab tests it caused greater loss of fat and gains of lean muscle than anavar (they say something like 11.5%).
I don't know about it being as effective as anavar, but it actually is a good product and does what it says to an extent (but it costs a bit, like most biotest products). It is, however, nothing like anavar in terms of the way it functions, and it is basically completely safe.
This may not at all be why you were asking, but it just reminded me of it.
