Test cyp/tbol/var cycle

Hey guys just looking for some opinions on my next cycle and some advice for pct...

26 years old (training for over 6 years)
This will be my 3rd cycle , the previous two just test and winny
6'2 , 218 lbs , 13 % BF
My goal is to put on 15-20 lbs lean muscle

Week 1-14 - Test Cyp @ 600 mg PW (300mg twice a week)
Week 1-6 - T-Bol @ 60mg ED week 1-3 , 70mg ED week 4-6
Week 9-14 - Anavar @ 70mg ED

Also : run Arimidex @ .25 EOD from start of cycle until end of PCT
I will take the 3 weeks between Tbol and Var to give my liver a little rest (I will also take milk thistle throughout cycle)

I plan on starting PCT 3 weeks after last pin , and I would like to use HCG this cycle (never have used it before)

What'd you recommend for PCT ? When to begin HCG and @ what dosage ?
I plan on running the clomid all 4 weeks of PCT what dosage do you recommend? And should I add Nolva as well?

How does this cycle look otherwise ? Please give me input on PCT because I dont want to begin cycle until I have all my PCT gear on hand.

Thanks looking forward to hearing some expertise!

Forgot to mention my testicle atrophy never fully recovered from last cycle( I ran clomid only for PCT, didn't know much about HCG at the time) so I now know HCG is what I need to get this time around but I have heard mixed responses on when to run HCG some say at the end of cycle and some say throughout. I feel like running throughout would be nest to try to prevent any further "shrinkage" , but I also heard running HCG throughout the entire cycle you risk permanently shutting down your natural testosterone production, is this true ?

And by "giving my liver a rest" between weeks 6 and 9 I just meant no orals , I will still be running Test Cyp at same dosage...

At reasonable doses, var isn't very harsh on the liver according to the literature available here on this site. Oral T-Bol is slightly higher hepatoxicity but without access to blood work figures, we are all just guessing here.
I plan on running T-Bol and Var at the same time with Test. I hope to be able to do regular blood draws to look for liver issues and to monitor my Test levels every couple of weeks. I plan on posting the results here for people to see.

What kind of pct do you plan on running ?
