man
I understand your concern put there is a thin line between caution and paranoia.
Thousands upon thousands have been doing more gear than you could do in 6 months in 2 weeks. From the 60's to today.
Most these people are still alive in their 40's ,50's, and 60's( According to many people the amount they used would have resulted in them needing new livers, kindneys and hearts by now. Alot of average american already might have died from heart attacks and cancer, but these abusers(the amount they use) are still up and kickin. I find that funny. And even in your local gyms you will find users in their 40's that have been on for like 15-20 years(long cycles to).
Anavar is a "safer" roid. You will be more than fine. I think the key to being safe with roids(especially long term use) is watching the other things you injest(painkillers, alcohol, rec drugs.) Thats where you see the deaths coming from(like pro wrestlers.)
Alot of people have said exercising raises liver values enough to have doctors shit. Its hard to know what to go buy. Its scary but most people hanging around these boards no more than most doctors about steriod use, so doctors only parrot media propaganda and scare the shit outta you!! Like you are going to be infertile. LOL
