A couple of points to consider:
1) 100mg every 2 weeks is not enough or frequent enough to do anything other than screw your hormones up further. I'd suggest no TRT rather than that protocol. You've read it before in the other threads, so I'll just reiterate it here. You should start out with a dose of around 100mg per week split into at least 2 doses (e.g. 50 mg spaced 3 and 4 days apart). I much prefer the every 3 day method (E3D) because then the intervals are even and slightly more frequent than the 3/4 day split. This also allows you to draw labs at any of the scheduled doses, whereas with the 3/4 days split you have to target a specific day of the week all the time so that the labs are comparable. A helpful hint for the E3D protocol is to program it into you computer calendar and sync it with your cell phone calendar and set them with alarms. That way you'll never miss a dose, which is actually easy to do with these more frequent protocols because you hormone levels are very constant and you have not of the up and down mood swings from the archaic weekly, or worse biweekly protocols.
2) At you level of 100 mg E2W, you have no need to worry about excess conversion to E. Quite the opposite. Your natural hormones will be suppressed, so the last week of the 2 week cycle you will be way below normal (and feel like crap). E naturally follows T, so when T is in the dumpster, so will your E. Most guys as paranoid of E, which is a carryover from what they've read in the bodybuilding forums where they use ridiculously high levels of T and/or aromatizable synthetic steroids that convert to E and/or have progestin-like activity. The two in combination (as BB often stack) is a recipe for gynecomastia. However, if you keep your T within physiological levels at all times (as will happen with a 100mg E3D protocol), E should also remain within physiological ranges. Guys need E too for normal erections and libido. It's an irony of nature, but you go limp without it. A word to the wise is NEVER mess around with an AI unless you have labs (and I mean the correct labs) that show your E is out of range. ALWAYS, ALWAYS, insist on the male "sensitive" assay. Never use the standard female lab (most docs don't know the difference). You will always test high for E with the standard female lab and end up crushing your with unnecessary AI treatments and end up with a bad case of ED. The best lab is the LabCorp LC/MS/MS method. Get it yourself if the doc won't order it:

3) I would focus on getting you T protocol dialed in and stable and then layer on HCG. Yes, you balls will shrivel up to the size of peanuts with T and you can preserve testicular size and function with HCG. I'd start out with a dose of around 500 IU per week split into 3 injections spaced roughly equally apart. I always stop HCG a week or so before my scheduled labs to get a reading on just the TRT part of the protocol and so my labs are comparable. At 500 IU per week, your T levels will be boosted about 300 ng/dL above the no HCG labs. Just keep that in mind when interpreting the results.
4) Regarding target T doses, you should focus on Free T and not Total T. SHBG levels can effect Free T and it's Free T that is biologically active. I always shoot for the upper 75th percentile of the 20 to 30 year old range, which is about 21 to 22 pg/mL Free T using LabCorp. However, ranges vary from lab to lab, so keep that in mind. If your SHBG is about mid-range, the Total T necessary to get that level of free T will be around 800 to 1000 ng/dL, but is HIGHLY dependent on the exact level of SHBG. Again, I never use Total T to interpret my labs, I ALWAYS look at Free T.
5) Finally, get a new doc. Any doc that prescribes 100mg every 2 weeks should have their license revoked.
