HCG inhibits LH production both directly (as an agonist of the LH receptor) and indirectly (via increasing testosterone and thusly estradiol) and so if your low T is from still-reduced LH production, HCG is the last thing that would help there.
Or more accurately, it's not in line at all so far as being something that will help LH production.
It would be better to try just the Arimidex and Nolvadex, or Arimidex alone, and getting a blood test (it's not expensive and a prescription can be obtained online) say 2 weeks into starting any program. Don't drive E2 levels below the normal range, but the bottom end of the normal range is a good place to be.
If E2 levels are taken to low normal, Nolvadex may not be necessary.
