yea buddy. heres why, SD is so f-ing strong that after that anything you take, after that will have to be stronger.....and good luck pulling that one off. take the bold, let it kick it, give it about a week after that to add the SD. the cycle i'm doing now is a H-drol/SD cycle. H-Drol takes a while to kick in too, so i took h-drol for 4 weeks then started SD, both at the same time, i'm just keeping the SD addition short. maybe 2 weeks or 3 at the very most..........
