Why not both? there both very anabolic compounds and both easy on the liver. I have used tbol and loved it! I used it at 80mg the first two weeks and 100mg the thrid and fourth week.
Anavar is the only steroids that has actually been shown to aid in fat loss but its not a very good mass builder at all...tbol is a big better at mass building and it really makes your muscle feel full and make you extremely vascular!
you could try: 80mg tbol/40mg var a day for 6 weeks.
