Dbol Test Cycle

I’m 25 years old and have been lifting for 8+ years. I’m 6 feet tall and 215 with 12-15ish body fat. Looking to bulk up and keep it relatively lean. Here’s my cycle

1-4 weeks Dbol 40 mg Ed (split)

1-12 test E 500 mg

I need advice for an AI and when exactly to use it. I was thinking Aromisin or Arimidex.

PCT is going to be Nolvadex
