Low T and LH=5.4 suggests primary hypogonadism. FSH should have also been tested, but too late now except one time to rule out testicular cancer.
Prolactin needs to be tested a possible cause which would if high, indicate a prolactin secreting pituitary adinoma [easily managed]. There is risk of damage to optic nerves if that is allowed to advance, so this screening is prudent and necessary.
200mg T per week is stupid, but seems to be fashion lately. T–>E2 will cause a lot of problems and blood count can be messed up seriously. That is somewhat age dependent and you have kept that a secret.
hCG should be 250iu SC EOD
TSH=1.91 is seriously a problem, normal lab results are not the issue.
If you are lucky, you have not been using iodized salt and that can be easily fixed.
Please see the last paragraph in this post.
We see so many thyroid issues with low T it is tempting to reach for cause and effect.

Evaluate your overall thyroid function by checking oral body temperatures as per the thyroid basics sticky. Thyroid hormone fT3 is what gets the job done and it regulates mitochondrial activity, the source of ATP which is the universal currency of cellular energy. This is part of the body’s temperature control loop. This can get messed up if you are iodine deficient. In many countries, you need to be using iodized salt. Other countries add iodine to dairy or bread.
