But it is toxic!!
Oxandrolone shares the liver toxicity problems common to 17-alkylated steroids. At one time it was thought that it did not, but both clinical and practical experience with Oxandrin has shown that at doses of 40 mg/day and higher, liver toxicity is indeed an issue with prolonged use.
The above information is from oxandrolone drug profile by Bill Roberts. You would be better off taking two 8 week cycles maybe summer and winter or something like that.
