It binds well to the AR so you should see some reduction in fat. Otherwise it's a pretty weak steroid and even at 600mgs per wk won't do a whole lot for you. I use mast, which is very similar but without the weighted esters. So 500mgs of mast will yield more mast than 500mgs of prob will yield prob. Just out of curiosity, why are you looking forward to this cycle? What are you expecting?
