IM Trestolone @ 300-500mg/wk. Other than that, probably these three are on par with each other as far as "potency", results would vary though: 30mg MSTEN daily 45-60mg DMZ daily 60mg M1A daily All of these are capable of giving 10-20lb gains with the right diet, conditions and genetics. I think IronFlex has some sort of Dbol PH that just released. Might look into that as well.
