I wouldn't do sust. I would stick to single esters.
For a frontload I would suggest doubling your dose until you reach the half life of the compound then go to your normal dose,
If you running dbol for a kick start I would just run it and test e.
I don't know if you have ever done prop before but it can be very painfull.
I would suggest
1-15 test c or test e 500mg
1-4 dbol 25mg-50mg
If you haven't done dbol before you'll probably wanna keep it on the low end
