SBCing is indeed intended on using higher doses and a shorter duration so that you won't get the unwanted sides... If you time it right you won't have the nasty sides... However they can creep up on you very fast - in that case drop everything and pct!
I also believe in frontloading short esters... Also this depends on your prop dosage... If run your prop a lot higher imho! If your used to running say 500mgs of test.... I'd do at least a G(if not higher if you know how your body handles it) on a SBC... Your defeating the purpose of running a SBC if you keep dosages moderate -
I'd run your tren a at 500
Prop at 750-1.25g depends on you!
Backload your d-Bol as its too short to pulse! 50mgs Ed or combine d-Bol/& drol
