Testosterone replacement isn't for size, and you don't get to pick from a list of steroids. You will probably be put on Test C or Test E. Probably somewhere between 100mg and 200mg a week. Don't double up on the dose or anything like that. Follow the doctor's instructions so you can get your levels right and stable. Maybe ask about HCG so your testicles don't shrink.
Having said that, you will probably see some gains in the beginning.
