I forgot to add that along with my TRT plan mentioned above I'm also prescribed threw my doctor T3/T4 medication. So my thyroid levels are kept at optimum levels. I have hashimoto (autoimmune disease) not bad the number wasn't that high to begin with and with the T3/T4 meds and taking a selenium supplement my number has dropped to the low 100's. I also take LDN which may have helped too but definitely helped with the awesome sleep quality I get since I started taking the LDN.
