you are taking advice from a dead guy who abused these things? think about this logically
and he is wrong. you don't use hcg during PCT under any circumstance if you want to recover. the simple reason why is it will DELAY recovery. it is a hormone after all

.. that would be like taking testosterone in pct.. yeah you feel better huh? well no shit. is that recovering you though? fuck no
now having said that lets be honest with ourselves here.
1. how was your HPTA's health BEFORE that cycle?
2. 20 weeks + esters means your pituitary glands were shut down for 26 some weeks straight.. that is 6 fucking months!!
3. in my experience (and i have a shit ton of it) any cycle exceeding 12 weeks is already tough to recover from. that is why i tell guys stick to 8-12 week cycles AT MOST. and i prefer 10 weeks for long esters. ya ya ya you are leaving gains on the table, but so what.
i would say it will take you a full 8 months to recover from that cycle, it can be done but it won't be fun. and it isn't about throwing a bunch of drugs at the problem either.. ONLY the body can recover. pct is designed to give you a soft landing
