Of course, the key is going to be diet. I have helped guys running 200mg test prop and 50mg winstrol with some AI and they have gotten shredded.
One thing is for sure, you are going to need to pay close attention to your estrogen. Letro is good, but adex should be good too. You need to avoid letting estrogen get too high in the first place. Then you won't need to blast the letro. If you use letro remember that it is very strong and it would be easy to take estrogen too low, which also will produce unwanted effects. Test/Mast with anavar at the end would work very nicely.
Test, anywhere from 2-400mg EW
Mast, at 400mg
and var for the last 6 or so wks, at 50mg
Adding in a fat burner like clen would also help
Then be sure to use a solid PCT
