fT3=4.0 [2-4.4] is well above midrange and I can see how this would reduce TSH via negative feedback. What are your oral body temperatures? Energy levels?
Concern? yes, there may be something abnormal. One could consider that there could be an early state of hypothyroid sim with thyroid nodules, but then fT4 would be high as well BUT your fT4 is well below mid-range. The only profile that your labs easily match is someone taking T3 medication.
What really matters is oral body temperatures that are a great indicator of overall thyroid function, see last paragraph in this post.

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.
As you are injecting twice a week, and if you have not been missing any doses, it appears that you could use more T. It would be helpful to have FT or SHBG to see what that implies.
Try to get E2 tested. Are you where you can do labs on your own if needed?
Dark skiin makes you much more prone to vitamin D deficiency, depending on climate and sun exposure. You may need to be taking Vit-D3. Vit-D3 is stored as a reservoir for Vit_D3—>Vit_25 which is really a hormone that is critical for proper DNA expression and cellular function.
