kickstarting a 10 week cycle

I’m looking to do a kickstart on my next cycle. It will be testosterone 500mgs a week. Gonna kickstart with 30mgs a day of dbol with it. My goals are bulking up.
How much of an AI would you say would be a wise choice here and do I need to start it from week 1 or should I wait to get results?
My stats are 37, 5’11’’ 183 pounds and around 17% body fat
