I have not, SD scares me. But i have read a lot into it since a lot of my friends have done clones of SD (eg. Mass Tabs). When i started to research on pros as well as AAS, D-Zine seemed pretty spectacular, as well as reading a lot of D-Zine logs over at PHF. Being 2 SD joined together your bodies stomach acid separates the two molecules prior to absorption, so it becomes a single molecule just with two potential pathways. The one advantage that Dymethazine has over Superdrol, from what i read, is the less likelihood of side effects or in the event of side effects being present they’re typically more manageable with D-Zone. Don’t take this as it being side-effect free, Dymethazine is an incredibly potent compound and carries the same risks as any other powerful anabolic steroid or pro-hormone.
