The first place to start would be diet.
If you think you have gyno post some pictures so we can look.
If you think your prone to gyno dont mess around and run an AI on your cycle.
Since you listed the compounds you did last time but not the dose ill do something similar.
Get your diet sorted out for the weight you want to be, cut the caloric difference in half. If you have 1700 in maintainance and you need 2000 to be 200 pounds add 150 to your 1700 for a total of 1850, in 3 months or so add the other 150 in.
Get your training sorted out: 5 days a week of lifting, some type of split training, and 2-3 days of cardio (swimming, running, walking, whatever)
Get your rest sorted out: 8 hours of sleep a day every day.
Start this cycle and continue the above for the next 22+ Weeks.
