I'll speak to the HCG portion; I think it should absolutely be run during your cycle. 2 injections/week, 250iu per. Personally I like too see it run from day 1 of test to the last injection, but some advise waiting a couple weeks to begin. Either way, run it during.
During post cycle I'd add DAA and Erase or Erase Pro-I feel these 2 combined is one of the best PCT (or even standalone) combos out there for natty test and killing estrogen while reducing bloat.
