We don't promote the use of thyroid meds in this community. If you are concerned about the effects of HGH on T4 and Tren on T3, run bloods and look. If, in fact, you're running into issues let an endo manage it. You don't have to disclose your GH or AAS use. It's one thing to let a doc restore your levels to a normal range if you are having, for example, unbearable symptoms and quite another to get a recommended exogenous dosage from an Internet forum like this and experiment. Yes, I've taken risks and done things that are dangerous to my health. My body, my decision. Advocating that you go do it is another matter entirely. There are other effective ways to burn fat off than tampering so grossly with your metabolism by messing around with thryroid hormones as you yourself pointed out below.
