@thomas00 The T4 I'm taking is very low dose (12.5 mcg). You think I'd be better without it?
I think if you are going to take thyroid you'd be a lot better off taking a product that has t3 combined with t4, or just t3 if that's what's suitable for you.
Ray has talked about studies of t4 only treatments shutting down cell respiration, sending people into comas in large enough doses etc for some people even 12.5mcg is enough to cause some serious problems.
