Dbol can be run for a longer time with less side effects. For this reason, I would suggest Dbol over Sdrol. Either of them are best used as a kick start for a longer injectable cycle. So an example of how they would be used is like this
1-12
Test E 500mg EW
adex .5mg EOD
1-6
Dbol 30mg EW
PCT starts 2 wks after last shot
OR.....
1-12
Test E 500mg EW
adex .5mg EOD
wk 1
Sdrol 10mg ED
wk 2 and 3
Sdrol 20 mg ED
PCT starts 2 wks after last shot
