I have hashimotos. I had a TSH well into the 20s, if I remember right, (range was 1-4ish). I was diagnosed around 15 years old (33 now).
Doc prescribed me synthroid, but quit before my blood ever got stabilized. I was young and didn’t think I needed to take meds for the rest of my life.
I went back on it for a while several years later, but didn’t feel any different. I then went to a naturopath, and we played with levothyroxine, Armour Thyroid, synthetic T3, Cortisol, etc.
All of that made me feel way worse. For me T3 was a bad idea. The half-life is so short (1 day) it makes you swing between hypo and hyper thyroid and my bloods were never stable. I tried different dosing for a good year before going back to just T4.
I’ve been on T4 now for several years at the same dose. I can say with certainty the only symptom it actually helped me with is my hair and nails. My hair used to be brittle, curly, and thin. Now it’s stronger and thicker. My toe nails used to split in half and now they don’t. I also had an orange tint to the skin of my toes which is gone now.
Unfortunately my energy, depression, sleep, and motivation have always been pretty bad and never improved with thyroid, Which is why I started looking into TRT.
I’ve been through it all with thyroid, so I would be happy to answer questions about it.
