Oxandrolone is a potent AS, but you need male doses, that is at least 30mg ed or more. that will cost a lot more than the equivalent potent amound of test enanthate, sustanon oder dbol. There are also a lot more fakes of Anavar around. And although its said to be a "mild" steroid, its actually 17aa and equally harsh on the liver like dbol or anadrol when compared on a mg-per-mg basis. besides for females i don't see any reason to use it for mass building purposes.
