500mg test c first cycle

Hi, this is my first hoping on gear.
I’ve been working out around 10yrs on and off
(Completely natural)
I’m 6’2 currently weigh 195. 28yrs old.
My plan is take 500mg a week split it into 2 shots for 16weeks.
I’m not quite sure what pct would I need.
I saw a lot of ppl saying do nolvadex 2 weeks after last shot, 40 40 20 20 per day 19~22week
I also got arimidex and clomid on hand just in case.

Any suggestions for pct and what results to expect from this cycle.
