250mg/wk of test-e is not enough to get the results I assume you're looking for...However it is enough to shut you down, so I'd say no lower than 400mg/wk, and for most there is no need to go above 20mg/day of m-drol. This is how i'd do it:
Test-E-450mg/wk - Wks 1-10(or12) shot 2xweek
M-Drol - 10mg/wk - Wks 1-2
M-Drol - 20mg/wk - Wk 3
I have experience with both compounds and I think this should be a major improvement over your plan
If this is your first time on m-drol I'd say run it 10/10/10 straight through.
