i've got 7500mg of Test E on its way

super excited. I have some concerns though, and while I have done large amounts of research I figured I would run this by some actual people..
stats:
1) 24 years old
2) 6'3" 190lbs. Not sure of bf%, maybe like 10%
3) 1 year of steady, dedicated training
4) no previous cycle experience
5) train 5 days a week (off weekends) 1 muscle group per day, 1 hour to 1 hour and 30 min per workout typically. (going to be eating a 3000 calorie diet 1 week before beginning test e shots and then throughout the 12 week cycle)
6) my cycle goals are really to just gain some muscle, break through 200lbs again and to have my clothes fit better... fill them out more i guess you know
okay like i said i have 7500mg of Test E on its way. my plan thus far is to hit week 1-4 with 500mg. week 5-8 1000mg (500mg monday, 500mg thursday) week 9 and week 10 500mg, week 11 and week 12 at 250mg.
I haven't ordered anything for PCT yet, or anything to prevent GYNO which is maybe my only real concern with this new adventure... i wonder how common is developing gyno from a test cycle like i described above?
any tips/advice/feedback is greatly appreciated.
