I just started a dbol/Sustanon 250 cycle this week and I've been taking them two at a time three times a day and they seem to be working well for me. My muscles are noticably more full looking already possibly due to some water retention but none the less my biceps and pecs seam to be hard as rocks. Wicked pumps. The first two days I took 20mg's 1 every four hours and then I bumped it up to 30mg's.
