I would do something like 300 mg of testosterone and add in an oral. You could add in a bulking oral like Anadrol or Dbol, or you could add in more of a cutter like Anavar or T-bol.
I've tried Superdrol as high as 40 mg a day and thought I was going to die. Definitely 20 to 30 mg is the maximum dosage and don't go more than 3 or 4 weeks.
