So after quite a time ie over a year of taking just T3 and increasing to about 75mcg daily and no T4 I have started to feel they are not good on their own. My blood tests came back with practically non existent T4 and top of range T3. I know the T4 can be very low on T3 only but it didn't seem right. I have felt quite depressed and achy and putting on weight. Also heavy eyes and tiredness.
I think it might be an idea to introduce some T4 ( I still have quite alot left within date from the doctor) and wonder if I might be better to have a more balanced blood test result.
I wonder whether the T3 only with non existent T4 reading is too heavy for me.
What is everyone elses experience. I came off T4 initially because it was thought I wasn't converting it and I was achy, swollen and generally feeling quite ill.
