Using HCG Mid-Cycle?

I am planning on running a 16 week cycle in preparation for a show. I wanted some advice on how to run some HCG mid cycle to keep the boys from atrophy. The Deca usually hits me hard that way. I also plan on using Hcg during actual PCT.

Weeks out:
16-8 Test E 400 mg/Deca 300mg/Nolva 20mg
8-1 Test P 200 mg/Mast P 400mg/Nolva 10mg

Any advice on dosage for the mid cycle and PCT is greatly appreciated. I have Clomid/Nolva/Hcg.
I’m 35, 210 on my 5th show.
