It comes down to preference I think... you can bulk or lean out with either, depending on diet... if you compare mg per mg, then one could argue that T-bol is stronger because typical "effective dosages" for T-bol are lower than dosages of Anavar that people typically run... both will suppress you, either could shut you down if you take enough... the beauty of either is that sides are typically lower than say d-bol, oral winny,
