I'd do the meo-TST in the beginning and the Dbol (or Turinabol or var, much much better as finishing compounds IMO) at the end.
Why?
Methyls jack liver enzymes real high. What they do? Break down androgens is what. So your cycle will be somewhat less effective if you start with a methyl than if you start with something gentler.
Meo-TST isn't methylated so it *PROBABLY* jacks the liver enzymes less than Dbol.
Finishing with a methyl OTOH ensures you clear everything up nice and good.
Does this make a humongous difference or not? I don't know and we probably never will, unless an actual study is done. Which it won't.
