well that is on the low end for dbol for 200lb. I would start at 30mg a day myself. And you really need an AI to go with the dbol. anastrozole, exemestane, or mesterolone. This is one cycle that I would run the AI at something other then the min dose, This works the best if the dbol is kept in check. I would run something like this
30mg dbol ED for weeks 1 to 6
75mg tren a EOD for weeks 1 to 6
AI of your choice here weeks 1 to 6
Nolvadex for post cycle therapy and as need otherwise.
Test is always good with this as well.
