E2=30.5pg/ml with midrange T suggests that you are not clearing E2 as effectively as one would hope or maybe you have higher amounts of body fat where T can aromatize to E2. You will feel better nearer to E2=22pg/ml. Your current T and E2 levels make you quite estrogen dominant.
Anastrozole is all that is needed, DIM complicates things and ties you down to a compounding pharmacy. To get near E2=22pg/ml, increase dose by a factor of 30/22. But if you switch to TRT, everything goes out the window. Your LH=8 may be pushing up testicular T-->E2 as well. If that is the case, we know that anastrozole cannot control T-->E2 inside the testes - docs do not understand the reasons why. T levels inside the testes are very high and the T competitive anastrozole simply is out gunned. In some cases, T levels inside the testes can approach 100X serum T levels.
LH=8 is very strong, pituitary is working well with clomid. Your testes are weak and after this time, the testes have fully responded to LH and it does not get any better. A restart seems unobtainable and hCG would not be an option as that is simply more LH receptor activation which is shown to be insufficient. More clomid will simply may E2 worse.
With low body temps and low thyroid function, we can expect that transdermal T delivery would fail, leaving self-injected T as your best option.
The lab ranges of thyroid hormones are overly broad and the ranges include many who are not doing well. TSH should be closer to 1.0, T3, T4, fT3, fT4 should be midrange or a bit higher. If you have adrenal fatigue from stresses, there is a whole new level of complications.
TSH range 0.5 - 5.5 typical implies that people can have an 11:1 range of this hormone and be "normal". Does not happen. And this statistical normal range is now interpreted to be a "normal" state of health which is ridiculous.
What was your source of iodine before?
Outer eyebrows sparse?
Dry skin or general hair thinning?
Feeling cold easily?
Thyroid can easily make your energy levels low, affecting every system in your body and create mood/depression issues.
The drastic change in prolactin is unexplained and a third lab would clarify. But the higher reading was not a concern and there is not evidence that prolactin affecting T levels.
