Bridging Mdrol

Im looking to run a 4wk cycle of mdrol. This is the third time with mdrol. Ive also done hdrol and m lmg. I want something to help keep gains. I wanted to bridge with tren for a few weeks before since the mdrol has such a harsh shutdown at the end.

I gained 20lbs each time but only kept 10 so id like to keep a little more this time. I figured if i did a total of 7wks or so, itd be a much better cycle. 4wks of tren into 4wks of mdrol, combining them at wk 4. Any thoughts or suggestions?
