I would run adex, unless bloodwork shows it's not needed. There are other side effects of elevated estrogen that aren't seen and people handle doses differently.
Run the hcg at 250iu 2-3x a week. Starting no later than week 3 stopping 4-5 days before pct.
Clomid and nolva are both fine together, or run one or the other. From my experience I liked using them both.
Run it like this if you choose both
I also like to taper off the serms for another two weeks dropping the dose in week 5 and 6, to help prevent any rebounds. Not needed but again that's what I preferred.
Test E 250mg 2x a week
Adex .25mg EOD, adjust need be
Hcg 250iu 2-3x a week, stopping 4-5 days before pct
Pct weeks 13-16/18
