not worth shutting urself down for 20 weeks just so u can run a little above trt dose, and yes i understand that trt=200mg test, but also trt for a lot of people=300mg +/week.
op, its ur body dawgs, but since ur already having low test levels (not really "low") and ur will to run a 20 weeker, than u might as well jump all in. go 5-750mg a week + winstrol.
400mg test will shut u down just as bad as 750mg, but the gains from 750 will be far better than 400mg. also u think recovery is easy? longest ive been on was 15 weeks, recovery after that took bout 4months after last shot to feel really "normal". just putting that out there, i didnt have hcg, but i did a pretty hard pct. u got hcg so idk mayb itll be easier to recover.
point is, its ur body, its ur decision. i just hope u understand this....your all in if u decide to start using. there really isnt a turn back especially at ur situation with already "low" test levels.
