My first cycle was test and tbol and I loved it! 40mg a day is a very low dose for tbol and to be honest you wont notice much other then vascularity and mabey 1-2lbs...bump it up to 80-100mg a day and you will grow like a weed! I ran:

80mg tbol a day weeks 1-2
100mg tbol a day weeks 3-4
500mg test weeks 1-10

I put on about 20lbs lean, strength shot through the roof! all my lifts went up atleast 30-60lbs. I also ran arimidex .5mg a day to keep bloat down as well.
