Your coach is an idiot and has no business coaching if he is going to recommend a reckless cycle like that
This is your first cycle and you only weigh 160, that's decent size at your height but you could absolutely still put on more size naturally
If you are hell bent on running a cycle then all I would recommend is halodrol
This is what it should look like
Cycle:
1-6 halodrol 50/50/75/75/100/100
1-6 liver support
3-6 hcgenerate
Pct:
7-10 clomid 25mg ed
7-10 formastanzol
7-10 post cycle unleashed combo
7-10 d-aspartic acid 3g ed
