I just finished my PCT after a Dimethadrol cycle (Dimethadrol = Dymethazine + Halodrol) and I had AWESOME results.
Week 1 was 25 mg Hdrol, 15 mg Dymeth.
Week 2 and 3 were 50 mg Hdrol, 30 mg Dymeth.
Week 4 was 75 mg Hdrol, 45 mg Dymeth.
Over the cycle I gained 25 lbs (went from about 150 to about 175). After PCT I am holding pretty steady at about 170. I was eating 3500-4000 cals a day though, so some of the weight gain was fat.
So, from my experience, dymethazie is pretty frickin great. Also, I don't think you should need any Superdrol (even at the low dose of 15 mg a day) since Dymethazine is very similar to SD - it seems like it would be overkill/wasteful.
