I was actually going to do this stack in Oct this year. But after thinking and reading a bit I have altered it. I too plan a lean mass bulk. I am using SD instead of megadrol though. It will consist of SD/TST/TRN.
Week 1: SD/TST
Week 2: SD/TST
Week 3: SD/TST
Week 4: TRN/TST
Week 5: TRN/TST
Week 6: TRN/TST
I was also going to run Arimidex and cycle support though the whole thing. Dosages are to your preference. This would be my 3rd oral cycle so my dosages will be a lil higher.
