Lowest said:Yes, in most cases thyroid levels rebound, just like test levels come back. The body is quite resilient in most cases. I've never seen a case where thyroid was actually shut down, but sometimes peoples thyroid levels never return to baseline. It's not a risk i'm personally worried about, but some people should be, like this guy.
Uh, what? Nobody ever said that thyroid "shuts down". That would imply that the thyroid doesn't produce any thyroid hormone at all, which never happens unless one has cancer or something. Hormone production is never "shut down" regardless of how much you abuse exogenous hormones - but normal production will so drastically lowered that it minuswell be.
But having the thyroid return to baseline occurs much more rarely like you think. Just like you find this forum littered with people that have extremely low levels of testosterone and can't recover after abusing AAS, many people will have a thyroid that won't return to baseline. Its common, so don't shrug it off.
