OK so I have seen some contradicting statements made about T2 thyroid hormone, more specifically that;
Administration of T2 does not effect the hypothalamic-pituitary-thyroid axis as much as T3 administration YET I read a study that mentioned;
Yet over at T-Nation and other sites I have read that no suppression occurs... This is just one of the contradictions I have seen...Originally Posted by PMID: 9651103
When people seem to refer to T2, they refer to the readily available 3,5-Diiodothyronine and then take the positives from either 3,5-T2 or 3,3'-T2 varieties and make it a positive for 3,5-Diiodothyronine exclusively... (No TSH suppression, increases in serum GH, increases activation of G6PD, and decarboxylates oxidative phosphorylation in the mitochondria)Originally Posted by PMID: 9651103
So I guess this leads to a question... Does 3,5-Diiodothyronine suppress TSH as much as T3?
Or at the end of the day which property is REALLY attributed to which configuration of T2 (3,3'-T2 or 3,5-T2)?
Food for thought, comments, couldn't care less???
