In terms of dosing, anywhere from 250 to 600 mg a week is good. You even see pros running it at 800 mg, but in your situation you will get just as good a result on half that.
Superdrol is one of those that you might run once or twice in your life and never run again. It's certainly worth experimenting with. I used to run it back in the day at 10 to 30 mg a day.
I love Anadrol and I love Dianabol, but you should pick one. Don't run both together, and if you run testosterone, you better make sure you use an AI as well.
