This brief comment in Thyroid (on a paper I can't yet find) shows T3 use is being slowly lifted out of the impossible and into the probable.

Excellent!!
Just managed to get to it - and it is Free Access! 
Thank you Diogenes. Your hard work is paying off and countless of people are hopefully are the beneficiaries. Does that mean that Medical Academia is getting trained now that T4 is not the be all for thyroid patients? And the importance of testing for FT3. And hopefully thyroid patients at last won't need to self medicate when it comes to T3 .
Thank you. Agree there's encouraging signs.
About time but it will probably take a whole generation of medical professionals to change their attitude. Thank you.
To quote Ovid...
"Dripping water hollows out stone, not through force but through persistence.”
What a coincidence! Shame we had to wait for Bianco to patent his slow release T3. Forgive my cynicism. I'm anticipating the day when I'm not allowed straight T3 because it's "physiologically inappropriate".
I'll still be dead before the stalwart UK endo position catches up.
They just don't seem to understand that dependency on T3 is/can be a life saving issue. Instead, the decision makers appear to think it's a "vanity" project that can be dismissed...and treated as only they ( think they) know how.
What would women patients know anyway!!
The endo said all I needed was ĺevo...despite that ending badly!
RTH was slowly draining away a vital hormone.
So, along with many of us, my only hope was to self medicate with self sourced T3.
Without T3-only I'd almost certainly be dying now...or dead!
The "probable" isn't good enough...
We need certainty!
Alas, one can still only dream!
I'm also cynical.
thyroid hormone resistance? not getting better on t4 alone or t4/t3 
Do some adding T3 feel worse before they get better?
Felt better with T3 now back to square one.
