DeprssiveJuice - Yes Oxandrolone is 17AA, but I think the thing is since it is highly anabolic - a relatively low MG dosage gets results (40-50 MG - Day). So in other words your liver only processes a small amount of the drug each day and is able to easily recoup.
To verify this look at results of AIDS patients given up to 40 MG ED of OX while also on AIDS Cocktails (confirmed liver toxic drugs). After 10 weeks of usage, only very few patiens drop out due to "slightly elevated liver values", and most of those are blaimed on the AIDS drugs NOT the OX.
I also read a few studies where children were given OX and after 10 weeks showed no signs of liver stress. Research for yourself.
Also on the UFC - Frank Vs. Tito was legendary. This should be a good fight, but Ken tends to gas and I think Tito will be to much for him. I have trained with Tito and he is like wrestling a boulder! Can't wait to see it anyway!
