Hello, 30 y.o male, 5'10'' , 190lbs 15 bf %

I've gone through a couple 10ml bottles of test in the last 10 years, usually doing 200-400mg for 6-8 weeks. I wasn't dieting right, and usual didn't keep my gains/or they turned to fat. I never ran any type of PCT or AI and I'm looking to do it right this time. I've looked at other threads, and am getting mixed reviews and would appreciate advice for this particular cycle Im running. Based on previous experience, I believe this to be the correct dosage for me to make maximum gains with limited side effects.

Week 1 - 4

Testosterone prop -75mg every other day

Week 1-12

Testosterone cyp. and enth. blend (I have both types, but not enough of one alone to run my cycle)
400mg week

1.) Now my question is, when should I start and finish my AI and how much should I use...daily or weekly? Should I even use an AI?

2.) Also, Should I use Nolv. or Clomid or both? when do I start? After the prop or after the cycle? How often and how much for this cycle? daily or weekly?

Any help or suggestions would be greatly appreciated
