i am a big fan of formestane on cycle, but i have never used sd or it's clones. i guess if i were to do it i would pre-load cycle assist for 7-10 days, and start formestane on day 1 of cycle and use at 2 pumps 2 x a day since that is how i did my xtren cycle. there is no reason to use suppress-c on cycle as ph's suppress cortisol already, but use it 2nd week of pct. from what i hear for a first time mdrol user 10mg first week and 20 for 2nd and 3rd weeks, most guys say 3 weeks is enough for 1st cycle. be on alert for sides and have a serm on hand before starting cycle. hope that helped, good luck.
