Thanks, I'll start with NDT first.some say T3 can raise cortisol, some on here say its rare
Peat said taking even more than 5mcg T3 at once can raise stress in the body since its a supraphysiological/non physiological amount
high dosing the dessicated thyroids might work better
or maybe, T4 and t3 combination therapy, there were some crazy pictures posted on twitter, before/after of t4 t3 combination, the person got 10 years older but looked over 10 years younger, had a very sharp jaw and looked much better after the apparent t4 t3 combination therapy
What got me interested with Thyroid Medications like Cytomel, is that Danny Roddy uses it as a daily supplement (if I remembered it correctly).
And he seems to not age or something, so there must be something to it like you've mentioned.
